@section intro What is Elementary?

This is a VERY SIMPLE toolkit. It is not meant for writing extensive desktop
applications (yet). Small simple ones with simple needs.

It is meant to make the programmers work almost brainless but give them lots
of flexibility.

@li @ref Start - Go here to quickly get started with writing Apps

@section organization Organization

One can divide Elemementary into three main groups:
@li @ref infralist - These are modules that deal with Elementary as a whole.
@li @ref widgetslist - These are the widgets you'll compose your UI out of.
@li @ref containerslist - These are the containers in which the widgets will be
                          layouted.

@section license License

LGPL v2 (see COPYING in the base of Elementary's source). This applies to
all files in the source tree.

@section ack Acknowledgements
There is a lot that goes into making a widget set, and they don't happen out of
nothing. It's like trying to make everyone everywhere happy, regardless of age,
gender, race or nationality - and that is really tough. So thanks to people and
organisations behind this, as listed in the @ref authors page.

/**
 * @defgroup Start Getting Started
 *
 * To write an Elementary app, you can get started with the following:
 *
@code
#include <Elementary.h>
EAPI_MAIN int
elm_main(int argc, char **argv)
{
   // create window(s) here and do any application init
   elm_run(); // run main loop
   elm_shutdown(); // after mainloop finishes running, shutdown
   return 0; // exit 0 for exit code
}
ELM_MAIN()
@endcode
 *
 * To use autotools (which helps in many ways in the long run, like being able
 * to immediately create releases of your software directly from your tree
 * and ensure everything needed to build it is there) you will need a
 * configure.ac, Makefile.am and autogen.sh file.
 *
 * configure.ac:
 *
@verbatim
AC_INIT(myapp, 0.0.0, myname@mydomain.com)
AC_PREREQ(2.52)
AC_CONFIG_SRCDIR(configure.ac)
AM_CONFIG_HEADER(config.h)
AC_PROG_CC
AM_INIT_AUTOMAKE(1.6 dist-bzip2)
PKG_CHECK_MODULES([ELEMENTARY], elementary)
AC_OUTPUT(Makefile)
@endverbatim
 *
 * Makefile.am:
 *
@verbatim
AUTOMAKE_OPTIONS = 1.4 foreign
MAINTAINERCLEANFILES = Makefile.in aclocal.m4 config.h.in configure depcomp install-sh missing

INCLUDES = -I$(top_srcdir)

bin_PROGRAMS = myapp

myapp_SOURCES = main.c
myapp_LDADD = @ELEMENTARY_LIBS@
myapp_CFLAGS = @ELEMENTARY_CFLAGS@
@endverbatim
 *
 * autogen.sh:
 *
@verbatim
#!/bin/sh
echo "Running aclocal..." ; aclocal $ACLOCAL_FLAGS || exit 1
echo "Running autoheader..." ; autoheader || exit 1
echo "Running autoconf..." ; autoconf || exit 1
echo "Running automake..." ; automake --add-missing --copy --gnu || exit 1
./configure "$@"
@endverbatim
 *
 * To generate all the things needed to bootstrap just run:
 *
@verbatim
./autogen.sh
@endverbatim
 *
 * This will generate Makefile.in's, the confgure script and everything else.
 * After this it works like all normal autotools projects:
@verbatim
./configure
make
sudo make install
@endverbatim
 *
 * Note sudo was assumed to get root permissions, as this would install in
 * /usr/local which is system-owned. Use any way you like to gain root, or
 * specify a different prefix with configure:
 *
@verbatim
./confiugre --prefix=$HOME/mysoftware
@endverbatim
 *
 * Also remember that autotools buys you some useful commands like:
@verbatim
make uninstall
@endverbatim
 *
 * This uninstalls the software after it was installed with "make install".
 * It is very useful to clear up what you built if you wish to clean the
 * system.
 *
@verbatim
make distcheck
@endverbatim
 *
 * This firstly checks if your build tree is "clean" and ready for
 * distribution. It also builds a tarball (myapp-0.0.0.tar.gz) that is
 * ready to upload and distribute to the world, that contains the generated
 * Makefile.in's and configure script. The users do not need to run
 * autogen.sh - just configure and on. They don't need autotools installed.
 * This tarball also builds cleanly, has all the sources it needs to build
 * included (that is sources for your application, not libraries it depends
 * on like Elementary). It builds cleanly in a buildroot and does not
 * contain any files that are temporarily generated like binaries and other
 * build-generated files, so the tarball is clean, and no need to worry
 * about cleaning up your tree before packaging.
 *
@verbatim
make clean
@endverbatim
 *
 * This cleans up all build files (binaries, objects etc.) from the tree.
 *
@verbatim
make distclean
@endverbatim
 *
 * This cleans out all files from the build and from configure's output too.
 *
@verbatim
make maintainer-clean
@endverbatim
 *
 * This deletes all the files autogen.sh will produce so the tree is clean
 * to be put into a revision-control system (like CVS, SVN or GIT for example).
 *
 * There is a more advanced way of making use of the quicklaunch infrastructure
 * in Elementary (which will not be covered here due to its more advanced
 * nature).
 *
 * Now let's actually create an interactive "Hello World" gui that you can
 * click the ok button to exit. It's more code because this now does something
 * much more significant, but it's still very simple:
 *
@code
#include <Elementary.h>

static void
on_done(void *data, Evas_Object *obj, void *event_info)
{
   // quit the mainloop (elm_run function will return)
   elm_exit();
}

EAPI_MAIN int
elm_main(int argc, char **argv)
{
   Evas_Object *win, *bg, *box, *lab, *btn;

   // new window - do the usual and give it a name, title and delete handler
   win = elm_win_add(NULL, "hello", ELM_WIN_BASIC);
   elm_win_title_set(win, "Hello");
   // when the user clicks "close" on a window there is a request to delete
   evas_object_smart_callback_add(win, "delete,request", on_done, NULL);

   // add a standard bg
   bg = elm_bg_add(win);
   // add object as a resize object for the window (controls window minimum
   // size as well as gets resized if window is resized)
   elm_win_resize_object_add(win, bg);
   evas_object_show(bg);

   // add a box object - default is vertical. a box holds children in a row,
   // either horizontally or vertically. nothing more.
   box = elm_box_add(win);
   // make the box hotizontal
   elm_box_horizontal_set(box, EINA_TRUE);
   // add object as a resize object for the window (controls window minimum
   // size as well as gets resized if window is resized)
   elm_win_resize_object_add(win, box);
   evas_object_show(box);

   // add a label widget, set the text and put it in the pad frame
   lab = elm_label_add(win);
   // set default text of the label
   elm_object_text_set(lab, "Hello out there world!");
   // pack the label at the end of the box
   elm_box_pack_end(box, lab);
   evas_object_show(lab);

   // add an ok button
   btn = elm_button_add(win);
   // set default text of button to "OK"
   elm_object_text_set(btn, "OK");
   // pack the button at the end of the box
   elm_box_pack_end(box, btn);
   evas_object_show(btn);
   // call on_done when button is clicked
   evas_object_smart_callback_add(btn, "clicked", on_done, NULL);

   // now we are done, show the window
   evas_object_show(win);

   // run the mainloop and process events and callbacks
   elm_run();
   return 0;
}
ELM_MAIN()
@endcode

   /**
    * Provide information in order to make Elementary determine the @b
    * run time location of the software in question, so other data files
    * such as images, sound files, executable utilities, libraries,
    * modules and locale files can be found.
    *
    * @param mainfunc This is your application's main function name,
    *        whose binary's location is to be found. Providing @c NULL
    *        will make Elementary not to use it
    * @param dom This will be used as the application's "domain", in the
    *        form of a prefix to any environment variables that may
    *        override prefix detection and the directory name, inside the
    *        standard share or data directories, where the software's
    *        data files will be looked for.
    * @param checkfile This is an (optional) magic file's path to check
    *        for existence (and it must be located in the data directory,
    *        under the share directory provided above). Its presence will
    *        help determine the prefix found was correct. Pass @c NULL if
    *        the check is not to be done.
    *
    * This function allows one to re-locate the application somewhere
    * else after compilation, if the developer wishes for easier
    * distribution of pre-compiled binaries.
    *
    * The prefix system is designed to locate where the given software is
    * installed (under a common path prefix) at run time and then report
    * specific locations of this prefix and common directories inside
    * this prefix like the binary, library, data and locale directories,
    * through the @c elm_app_*_get() family of functions.
    *
    * Call elm_app_info_set() early on before you change working
    * directory or anything about @c argv[0], so it gets accurate
    * information.
    *
    * It will then try and trace back which file @p mainfunc comes from,
    * if provided, to determine the application's prefix directory.
    *
    * The @p dom parameter provides a string prefix to prepend before
    * environment variables, allowing a fallback to @b specific
    * environment variables to locate the software. You would most
    * probably provide a lowercase string there, because it will also
    * serve as directory domain, explained next. For environment
    * variables purposes, this string is made uppercase. For example if
    * @c "myapp" is provided as the prefix, then the program would expect
    * @c "MYAPP_PREFIX" as a master environment variable to specify the
    * exact install prefix for the software, or more specific environment
    * variables like @c "MYAPP_BIN_DIR", @c "MYAPP_LIB_DIR", @c
    * "MYAPP_DATA_DIR" and @c "MYAPP_LOCALE_DIR", which could be set by
    * the user or scripts before launching. If not provided (@c NULL),
    * environment variables will not be used to override compiled-in
    * defaults or auto detections.
    *
    * The @p dom string also provides a subdirectory inside the system
    * shared data directory for data files. For example, if the system
    * directory is @c /usr/local/share, then this directory name is
    * appended, creating @c /usr/local/share/myapp, if it @p was @c
    * "myapp". It is expected the application installs data files in
    * this directory.
    *
    * The @p checkfile is a file name or path of something inside the
    * share or data directory to be used to test that the prefix
    * detection worked. For example, your app will install a wallpaper
    * image as @c /usr/local/share/myapp/images/wallpaper.jpg and so to
    * check that this worked, provide @c "images/wallpaper.jpg" as the @p
    * checkfile string.

   /**
    * @defgroup Theme Theme
    *
    * Elementary uses Edje to theme its widgets, naturally. But for the most
    * part this is hidden behind a simpler interface that lets the user set
    * extensions and choose the style of widgets in a much easier way.
    *
    * Instead of thinking in terms of paths to Edje files and their groups
    * each time you want to change the appearance of a widget, Elementary
    * works so you can add any theme file with extensions or replace the
    * main theme at one point in the application, and then just set the style
    * of widgets with elm_object_style_set() and related functions. Elementary
    * will then look in its list of themes for a matching group and apply it,
    * and when the theme changes midway through the application, all widgets
    * will be updated accordingly.
    *
    * There are three concepts you need to know to understand how Elementary
    * theming works: default theme, extensions and overlays.
    *
    * Default theme, obviously enough, is the one that provides the default
    * look of all widgets. End users can change the theme used by Elementary
    * by setting the @c ELM_THEME environment variable before running an
    * application, or globally for all programs using the @c elementary_config
    * utility. Applications can change the default theme using elm_theme_set(),
    * but this can go against the user wishes, so it's not an adviced practice.
    *
    * Ideally, applications should find everything they need in the already
    * provided theme, but there may be occasions when that's not enough and
    * custom styles are required to correctly express the idea. For this
    * cases, Elementary has extensions.
    *
    * Extensions allow the application developer to write styles of its own
    * to apply to some widgets. This requires knowledge of how each widget
    * is themed, as extensions will always replace the entire group used by
    * the widget, so important signals and parts need to be there for the
    * object to behave properly (see documentation of Edje for details).
    * Once the theme for the extension is done, the application needs to add
    * it to the list of themes Elementary will look into, using
    * elm_theme_extension_add(), and set the style of the desired widgets as
    * he would normally with elm_object_style_set().
    *
    * Overlays, on the other hand, can replace the look of all widgets by
    * overriding the default style. Like extensions, it's up to the application
    * developer to write the theme for the widgets it wants, the difference
    * being that when looking for the theme, Elementary will check first the
    * list of overlays, then the set theme and lastly the list of extensions,
    * so with overlays it's possible to replace the default view and every
    * widget will be affected. This is very much alike to setting the whole
    * theme for the application and will probably clash with the end user
    * options, not to mention the risk of ending up with not matching styles
    * across the program. Unless there's a very special reason to use them,
    * overlays should be avoided for the resons exposed before.
    *
    * All these theme lists are handled by ::Elm_Theme instances. Elementary
    * keeps one default internally and every function that receives one of
    * these can be called with NULL to refer to this default (except for
    * elm_theme_free()). It's possible to create a new instance of a
    * ::Elm_Theme to set other theme for a specific widget (and all of its
    * children), but this is as discouraged, if not even more so, than using
    * overlays. Don't use this unless you really know what you are doing.
    *
    * But to be less negative about things, you can look at the following
    * examples:
    * @li @ref theme_example_01 "Using extensions"
    * @li @ref theme_example_02 "Using overlays"

    *   "shot:[delay=XX][:][repeat=DDD][:][file=XX]"
    *
    * Where options are separated by a ":" char if more than one option is
    * given, with delay, if provided being the first option and file the last
    * (order is important). The delay specifies how long to wait after the
    * window is shown before doing the virtual "in memory" rendering and then
    * save the output to the file specified by the file option (and then exit).
    * If no delay is given, the default is 0.5 seconds. If no file is given the
    * default output file is "out.png". Repeat option is for continous
    * capturing screenshots. Repeat range is from 1 to 999 and filename is
    * fixed to "out001.png" Some examples of using the shot engine:
    *
    *   ELM_ENGINE="shot:delay=1.0:repeat=5:file=elm_test.png" elementary_test

    * An inwin is a window inside a window that is useful for a quick popup.
    * It does not hover.
    *
    * It works by creating an object that will occupy the entire window, so it
    * must be created using an @ref Win "elm_win" as parent only. The inwin
    * object can be hidden or restacked below every other object if it's
    * needed to show what's behind it without destroying it. If this is done,
    * the elm_win_inwin_activate() function can be used to bring it back to
    * full visibility again.
    *
    * There are three styles available in the default theme. These are:
    * @li default: The inwin is sized to take over most of the window it's
    * placed in.
    * @li minimal: The size of the inwin will be the minimum necessary to show
    * its contents.
    * @li minimal_vertical: Horizontally, the inwin takes as much space as
    * possible, but it's sized vertically the most it needs to fit its\
    * contents.
    *
    * Some examples of Inwin can be found in the following:
    * @li @ref inwin_example_01
    *
    * @{

    * Never call this function with anything other than the top-most window

    *
    * A box arranges objects in a linear fashion, governed by a layout function
    * that defines the details of this arrangement.
    *
    * By default, the box will use an internal function to set the layout to
    * a single row, either vertical or horizontal. This layout is affected
    * by a number of parameters, such as the homogeneous flag set by
    * elm_box_homogeneous_set(), the values given by elm_box_padding_set() and
    * elm_box_align_set() and the hints set to each object in the box.
    *
    * For this default layout, it's possible to change the orientation with
    * elm_box_horizontal_set(). The box will start in the vertical orientation,
    * placing its elements ordered from top to bottom. When horizontal is set,
    * the order will go from left to right. If the box is set to be
    * homogeneous, every object in it will be assigned the same space, that
    * of the largest object. Padding can be used to set some spacing between
    * the cell given to each object. The alignment of the box, set with
    * elm_box_align_set(), determines how the bounding box of all the elements
    * will be placed within the space given to the box widget itself.
    *
    * The size hints of each object also affect how they are placed and sized
    * within the box. evas_object_size_hint_min_set() will give the minimum
    * size the object can have, and the box will use it as the basis for all
    * latter calculations. Elementary widgets set their own minimum size as
    * needed, so there's rarely any need to use it manually.
    *
    * evas_object_size_hint_weight_set(), when not in homogeneous mode, is
    * used to tell whether the object will be allocated the minimum size it
    * needs or if the space given to it should be expanded. It's important
    * to realize that expanding the size given to the object is not the same
    * thing as resizing the object. It could very well end being a small
    * widget floating in a much larger empty space. If not set, the weight
    * for objects will normally be 0.0 for both axis, meaning the widget will
    * not be expanded. To take as much space possible, set the weight to
    * EVAS_HINT_EXPAND (defined to 1.0) for the desired axis to expand.
    *
    * Besides how much space each object is allocated, it's possible to control
    * how the widget will be placed within that space using
    * evas_object_size_hint_align_set(). By default, this value will be 0.5
    * for both axis, meaning the object will be centered, but any value from
    * 0.0 (left or top, for the @c x and @c y axis, respectively) to 1.0
    * (right or bottom) can be used. The special value EVAS_HINT_FILL, which
    * is -1.0, means the object will be resized to fill the entire space it
    * was allocated.
    *
    * In addition, customized functions to define the layout can be set, which
    * allow the application developer to organize the objects within the box
    * in any number of ways.
    *
    * The special elm_box_layout_transition() function can be used
    * to switch from one layout to another, animating the motion of the
    * children of the box.
    *
    * @note Objects should not be added to box objects using _add() calls.

    * elm_box_layout_set(box, elm_box_layout_transition, t,
    *                    elm_box_transition_free);
    * @endcode

    * This is an entry made to be filled with or display a <b>file

    * a @ref File_Selector_Button "file selector button" on its side,
    * which will raise an internal @ref Fileselector "file selector widget",
    * when clicked, for path selection aided by file system
    * navigation.
    *
    * This file selector may appear in an Elementary window or in an
    * inner window. When a file is chosen from it, the (inner) window
    * is closed and the selected file's path string is exposed both as
    * an smart event and as the new text on the entry.
    *
    * This widget encapsulates operations on its internal file
    * selector on its own API. There is less control over its file
    * selector than that one would have instatiating one directly.
    *
    * Smart callbacks one can register to:
    * - @c "changed" - The text within the entry was changed
    * - @c "activated" - The entry has had editing finished and
    *   changes are to be "committed"
    * - @c "press" - The entry has been clicked
    * - @c "longpressed" - The entry has been clicked (and held) for a
    *   couple seconds
    * - @c "clicked" - The entry has been clicked
    * - @c "clicked,double" - The entry has been double clicked
    * - @c "focused" - The entry has received focus
    * - @c "unfocused" - The entry has lost focus
    * - @c "selection,paste" - A paste action has occurred on the
    *   entry
    * - @c "selection,copy" - A copy action has occurred on the entry
    * - @c "selection,cut" - A cut action has occurred on the entry
    * - @c "unpressed" - The file selector entry's button was released
    *   after being pressed.
    * - @c "file,chosen" - The user has selected a path via the file

   /**
    * @defgroup Gengrid Gengrid (Generic grid)
    *
    * This widget aims to position objects in a grid layout while
    * actually creating and rendering only the visible ones, using the
    * same idea as the @ref Genlist "genlist": the user defines a @b
    * class for each item, specifying functions that will be called at
    * object creation, deletion, etc. When those items are selected by
    * the user, a callback function is issued. Users may interact with
    * a gengrid via the mouse (by clicking on items to select them and
    * clicking on the grid's viewport and swiping to pan the whole
    * view) or via the keyboard, navigating through item with the
    * arrow keys.
    *
    * @section Gengrid_Layouts Gengrid layouts
    *
    * Gengrids may layout its items in one of two possible layouts:
    * - horizontal or
    * - vertical.
    *
    * When in "horizontal mode", items will be placed in @b columns,
    * from top to bottom and, when the space for a column is filled,
    * another one is started on the right, thus expanding the grid
    * horizontally, making for horizontal scrolling. When in "vertical
    * mode" , though, items will be placed in @b rows, from left to
    * right and, when the space for a row is filled, another one is
    * started below, thus expanding the grid vertically (and making
    * for vertical scrolling).
    *
    * @section Gengrid_Items Gengrid items
    *
    * An item in a gengrid can have 0 or more text labels (they can be
    * regular text or textblock Evas objects - that's up to the style
    * to determine), 0 or more icons (which are simply objects
    * swallowed into the gengrid item's theming Edje object) and 0 or
    * more <b>boolean states</b>, which have the behavior left to the
    * user to define. The Edje part names for each of these properties
    * will be looked up, in the theme file for the gengrid, under the
    * Edje (string) data items named @c "labels", @c "icons" and @c
    * "states", respectively. For each of those properties, if more
    * than one part is provided, they must have names listed separated
    * by spaces in the data fields. For the default gengrid item
    * theme, we have @b one label part (@c "elm.text"), @b two icon
    * parts (@c "elm.swalllow.icon" and @c "elm.swallow.end") and @b
    * no state parts.
    *
    * A gengrid item may be at one of several styles. Elementary
    * provides one by default - "default", but this can be extended by
    * system or application custom themes/overlays/extensions (see
    * @ref Theme "themes" for more details).
    *
    * @section Gengrid_Item_Class Gengrid item classes
    *
    * In order to have the ability to add and delete items on the fly,
    * gengrid implements a class (callback) system where the
    * application provides a structure with information about that
    * type of item (gengrid may contain multiple different items with
    * different classes, states and styles). Gengrid will call the
    * functions in this struct (methods) when an item is "realized"
    * (i.e., created dynamically, while the user is scrolling the
    * grid). All objects will simply be deleted when no longer needed
    * with evas_object_del(). The #Elm_GenGrid_Item_Class structure
    * contains the following members:
    * - @c item_style - This is a constant string and simply defines
    * the name of the item style. It @b must be specified and the
    * default should be @c "default".
    * - @c func.label_get - This function is called when an item
    * object is actually created. The @c data parameter will point to
    * the same data passed to elm_gengrid_item_append() and related
    * item creation functions. The @c obj parameter is the gengrid
    * object itself, while the @c part one is the name string of one
    * of the existing text parts in the Edje group implementing the
    * item's theme. This function @b must return a strdup'()ed string,
    * as the caller will free() it when done. See
    * #Elm_Gengrid_Item_Label_Get_Cb.
    * - @c func.icon_get - This function is called when an item object
    * is actually created. The @c data parameter will point to the
    * same data passed to elm_gengrid_item_append() and related item
    * creation functions. The @c obj parameter is the gengrid object
    * itself, while the @c part one is the name string of one of the
    * existing (icon) swallow parts in the Edje group implementing the
    * item's theme. It must return @c NULL, when no icon is desired,
    * or a valid object handle, otherwise. The object will be deleted
    * by the gengrid on its deletion or when the item is "unrealized".
    * See #Elm_Gengrid_Item_Icon_Get_Cb.
    * - @c func.state_get - This function is called when an item
    * object is actually created. The @c data parameter will point to
    * the same data passed to elm_gengrid_item_append() and related
    * item creation functions. The @c obj parameter is the gengrid
    * object itself, while the @c part one is the name string of one
    * of the state parts in the Edje group implementing the item's
    * theme. Return @c EINA_FALSE for false/off or @c EINA_TRUE for
    * true/on. Gengrids will emit a signal to its theming Edje object
    * with @c "elm,state,XXX,active" and @c "elm" as "emission" and
    * "source" arguments, respectively, when the state is true (the
    * default is false), where @c XXX is the name of the (state) part.
    * See #Elm_Gengrid_Item_State_Get_Cb.
    * - @c func.del - This is called when elm_gengrid_item_del() is
    * called on an item or elm_gengrid_clear() is called on the
    * gengrid. This is intended for use when gengrid items are
    * deleted, so any data attached to the item (e.g. its data
    * parameter on creation) can be deleted. See #Elm_Gengrid_Item_Del_Cb.
    *
    * @section Gengrid_Usage_Hints Usage hints
    *
    * If the user wants to have multiple items selected at the same
    * time, elm_gengrid_multi_select_set() will permit it. If the
    * gengrid is single-selection only (the default), then
    * elm_gengrid_select_item_get() will return the selected item or
    * @c NULL, if none is selected. If the gengrid is under
    * multi-selection, then elm_gengrid_selected_items_get() will
    * return a list (that is only valid as long as no items are
    * modified (added, deleted, selected or unselected) of child items
    * on a gengrid.
    *
    * If an item changes (internal (boolean) state, label or icon
    * changes), then use elm_gengrid_item_update() to have gengrid
    * update the item with the new state. A gengrid will re-"realize"
    * the item, thus calling the functions in the
    * #Elm_Gengrid_Item_Class set for that item.
    *
    * To programmatically (un)select an item, use
    * elm_gengrid_item_selected_set(). To get its selected state use
    * elm_gengrid_item_selected_get(). To make an item disabled
    * (unable to be selected and appear differently) use
    * elm_gengrid_item_disabled_set() to set this and
    * elm_gengrid_item_disabled_get() to get the disabled state.
    *
    * Grid cells will only have their selection smart callbacks called
    * when firstly getting selected. Any further clicks will do
    * nothing, unless you enable the "always select mode", with
    * elm_gengrid_always_select_mode_set(), thus making every click to
    * issue selection callbacks. elm_gengrid_no_select_mode_set() will
    * turn off the ability to select items entirely in the widget and
    * they will neither appear selected nor call the selection smart
    * callbacks.
    *
    * Remember that you can create new styles and add your own theme
    * augmentation per application with elm_theme_extension_add(). If
    * you absolutely must have a specific style that overrides any
    * theme the user or system sets up you can use
    * elm_theme_overlay_add() to add such a file.
    *
    * @section Gengrid_Smart_Events Gengrid smart events
    *
    * Smart events that you can add callbacks for are:
    * - @c "activated" - The user has double-clicked or pressed
    *   (enter|return|spacebar) on an item. The @c event_info parameter
    *   is the gengrid item that was activated.
    * - @c "clicked,double" - The user has double-clicked an item.
    *   The @c event_info parameter is the gengrid item that was double-clicked.
    * - @c "longpressed" - This is called when the item is pressed for a certain
    *   amount of time. By default it's 1 second.
    * - @c "selected" - The user has made an item selected. The
    *   @c event_info parameter is the gengrid item that was selected.
    * - @c "unselected" - The user has made an item unselected. The
    *   @c event_info parameter is the gengrid item that was unselected.
    * - @c "realized" - This is called when the item in the gengrid
    *   has its implementing Evas object instantiated, de facto. @c
    *   event_info is the gengrid item that was created. The object
    *   may be deleted at any time, so it is highly advised to the
    *   caller @b not to use the object pointer returned from
    *   elm_gengrid_item_object_get(), because it may point to freed
    *   objects.
    * - @c "unrealized" - This is called when the implementing Evas
    *   object for this item is deleted. @c event_info is the gengrid
    *   item that was deleted.
    * - @c "changed" - Called when an item is added, removed, resized
    *   or moved and when the gengrid is resized or gets "horizontal"
    *   property changes.
    * - @c "scroll,anim,start" - This is called when scrolling animation has
    *   started.
    * - @c "scroll,anim,stop" - This is called when scrolling animation has
    *   stopped.
    * - @c "drag,start,up" - Called when the item in the gengrid has
    *   been dragged (not scrolled) up.
    * - @c "drag,start,down" - Called when the item in the gengrid has
    *   been dragged (not scrolled) down.
    * - @c "drag,start,left" - Called when the item in the gengrid has
    *   been dragged (not scrolled) left.
    * - @c "drag,start,right" - Called when the item in the gengrid has
    *   been dragged (not scrolled) right.
    * - @c "drag,stop" - Called when the item in the gengrid has
    *   stopped being dragged.
    * - @c "drag" - Called when the item in the gengrid is being
    *   dragged.
    * - @c "scroll" - called when the content has been scrolled
    *   (moved).
    * - @c "scroll,drag,start" - called when dragging the content has
    *   started.
    * - @c "scroll,drag,stop" - called when dragging the content has
    *   stopped.

    * This is a @b digital clock widget. In its default theme, it has a
    * vintage "flipping numbers clock" appearance, which will animate
    * sheets of individual algarisms individually as time goes by.
    *
    * A newly created clock will fetch system's time (already
    * considering local time adjustments) to start with, and will tick
    * accondingly. It may or may not show seconds.
    *
    * Clocks have an @b edition mode. When in it, the sheets will
    * display extra arrow indications on the top and bottom and the
    * user may click on them to raise or lower the time values. After
    * it's told to exit edition mode, it will keep ticking with that
    * new time set (it keeps the difference from local time).
    *
    * Also, when under edition mode, user clicks on the cited arrows
    * which are @b held for some time will make the clock to flip the
    * sheet, thus editing the time, continuosly and automatically for
    * the user. The interval between sheet flips will keep growing in
    * time, so that it helps the user to reach a time which is distant
    * from the one set.
    *
    * The time display is, by default, in military mode (24h), but an
    * am/pm indicator may be optionally shown, too, when it will
    * switch to 12h.
    *
    * Smart callbacks one can register to:
    * - "changed" - the clock's user changed the time
    *

    *
    * This is a container widget that takes a standard Edje design file and
    * wraps it very thinly in a widget.
    *
    * An Edje design (theme) file has a very wide range of possibilities to
    * describe the behavior of elements added to the Layout. Check out the Edje
    * documentation and the EDC reference to get more information about what can
    * be done with Edje.
    *
    * Just like @ref List, @ref Box, and other container widgets, any
    * object added to the Layout will become its child, meaning that it will be
    * deleted if the Layout is deleted, move if the Layout is moved, and so on.
    *
    * The Layout widget can contain as many Contents, Boxes or Tables as
    * described in its theme file. For instance, objects can be added to
    * different Tables by specifying the respective Table part names. The same
    * is valid for Content and Box.
    *
    * The objects added as child of the Layout will behave as described in the
    * part description where they were added. There are 3 possible types of
    * parts where a child can be added:
    *
    * @section secContent Content (SWALLOW part)
    *
    * Only one object can be added to the @c SWALLOW part (but you still can
    * have many @c SWALLOW parts and one object on each of them). Use the @c
    * elm_layout_content_* set of functions to set, retrieve and unset objects
    * as content of the @c SWALLOW. After being set to this part, the object
    * size, position, visibility, clipping and other description properties
    * will be totally controled by the description of the given part (inside
    * the Edje theme file).
    *
    * One can use @c evas_object_size_hint_* functions on the child to have some
    * kind of control over its behavior, but the resulting behavior will still
    * depend heavily on the @c SWALLOW part description.
    *
    * The Edje theme also can change the part description, based on signals or
    * scripts running inside the theme. This change can also be animated. All of
    * this will affect the child object set as content accordingly. The object
    * size will be changed if the part size is changed, it will animate move if
    * the part is moving, and so on.
    *
    * The following picture demonstrates a Layout widget with a child object
    * added to its @c SWALLOW:
    *
    * @image html layout_swallow.png
    * @image latex layout_swallow.eps width=\textwidth
    *
    * @section secBox Box (BOX part)
    *
    * An Edje @c BOX part is very similar to the Elementary @ref Box widget. It
    * allows one to add objects to the box and have them distributed along its
    * area, accordingly to the specified @a layout property (now by @a layout we
    * mean the chosen layouting design of the Box, not the Layout widget
    * itself).
    *
    * A similar effect for having a box with its position, size and other things
    * controled by the Layout theme would be to create an Elementary @ref Box
    * widget and add it as a Content in the @c SWALLOW part.
    *
    * The main difference of using the Layout Box is that its behavior, the box
    * properties like layouting format, padding, align, etc. will be all
    * controled by the theme. This means, for example, that a signal could be
    * sent to the Layout theme (with elm_object_signal_emit()) and the theme
    * handled the signal by changing the box padding, or align, or both. Using
    * the Elementary @ref Box widget is not necessarily harder or easier, it
    * just depends on the circunstances and requirements.
    *
    * The Layout Box can be used through the @c elm_layout_box_* set of
    * functions.
    *
    * The following picture demonstrates a Layout widget with many child objects
    * added to its @c BOX part:
    *
    * @image html layout_box.png
    * @image latex layout_box.eps width=\textwidth
    *
    * @section secTable Table (TABLE part)
    *
    * Just like the @ref secBox, the Layout Table is very similar to the
    * Elementary @ref Table widget. It allows one to add objects to the Table
    * specifying the row and column where the object should be added, and any
    * column or row span if necessary.
    *
    * Again, we could have this design by adding a @ref Table widget to the @c
    * SWALLOW part using elm_layout_content_set(). The same difference happens
    * here when choosing to use the Layout Table (a @c TABLE part) instead of
    * the @ref Table plus @c SWALLOW part. It's just a matter of convenience.
    *
    * The Layout Table can be used through the @c elm_layout_table_* set of
    * functions.
    *
    * The following picture demonstrates a Layout widget with many child objects
    * added to its @c TABLE part:
    *
    * @image html layout_table.png
    * @image latex layout_table.eps width=\textwidth
    *
    * @section secPredef Predefined Layouts
    *
    * Another interesting thing about the Layout widget is that it offers some
    * predefined themes that come with the default Elementary theme. These
    * themes can be set by the call elm_layout_theme_set(), and provide some
    * basic functionality depending on the theme used.
    *
    * Most of them already send some signals, some already provide a toolbar or
    * back and next buttons.
    *
    * These are available predefined theme layouts. All of them have class = @c
    * layout, group = @c application, and style = one of the following options:
    *
    * @li @c toolbar-content - application with toolbar and main content area
    * @li @c toolbar-content-back - application with toolbar and main content
    * area with a back button and title area
    * @li @c toolbar-content-back-next - application with toolbar and main
    * content area with a back and next buttons and title area
    * @li @c content-back - application with a main content area with a back

    *
    * An entry is a convenience widget which shows a box that the user can
    * enter text into. Entries by default don't scroll, so they grow to
    * accomodate the entire text, resizing the parent window as needed. This
    * can be changed with the elm_entry_scrollable_set() function.
    *
    * They can also be single line or multi line (the default) and when set
    * to multi line mode they support text wrapping in any of the modes
    * indicated by #Elm_Wrap_Type.
    *
    * Other features include password mode, filtering of inserted text with
    * elm_entry_text_filter_append() and related functions, inline "items" and
    * formatted markup text.
    *
    * @section entry-markup Formatted text
    *
    * The markup tags supported by the Entry are defined by the theme, but
    * even when writing new themes or extensions it's a good idea to stick to
    * a sane default, to maintain coherency and avoid application breakages.
    * Currently defined by the default theme are the following tags:
    * @li \<br\>: Inserts a line break.
    * @li \<ps\>: Inserts a paragraph separator. This is preferred over line
    * breaks.
    * @li \<tab\>: Inserts a tab.
    * @li \<em\>...\</em\>: Emphasis. Sets the @em oblique style for the
    * enclosed text.
    * @li \<b\>...\</b\>: Sets the @b bold style for the enclosed text.
    * @li \<link\>...\</link\>: Underlines the enclosed text.
    * @li \<hilight\>...\</hilight\>: Hilights the enclosed text.
    *
    * @section entry-special Special markups
    *
    * Besides those used to format text, entries support two special markup
    * tags used to insert clickable portions of text or items inlined within
    * the text.
    *
    * @subsection entry-anchors Anchors
    *
    * Anchors are similar to HTML anchors. Text can be surrounded by \<a\> and
    * \</a\> tags and an event will be generated when this text is clicked,
    * like this:
    *
    * @code
    * This text is outside <a href=anc-01>but this one is an anchor</a>
    * @endcode
    *
    * The @c href attribute in the opening tag gives the name that will be
    * used to identify the anchor and it can be any valid utf8 string.
    *
    * When an anchor is clicked, an @c "anchor,clicked" signal is emitted with
    * an #Elm_Entry_Anchor_Info in the @c event_info parameter for the
    * callback function. The same applies for "anchor,in" (mouse in), "anchor,out"
    * (mouse out), "anchor,down" (mouse down), and "anchor,up" (mouse up) events on
    * an anchor.
    *
    * @subsection entry-items Items
    *
    * Inlined in the text, any other @c Evas_Object can be inserted by using
    * \<item\> tags this way:
    *
    * @code
    * <item size=16x16 vsize=full href=emoticon/haha></item>
    * @endcode
    *
    * Just like with anchors, the @c href identifies each item, but these need,
    * in addition, to indicate their size, which is done using any one of
    * @c size, @c absize or @c relsize attributes. These attributes take their
    * value in the WxH format, where W is the width and H the height of the
    * item.
    *
    * @li absize: Absolute pixel size for the item. Whatever value is set will
    * be the item's size regardless of any scale value the object may have
    * been set to. The final line height will be adjusted to fit larger items.
    * @li size: Similar to @c absize, but it's adjusted to the scale value set
    * for the object.
    * @li relsize: Size is adjusted for the item to fit within the current
    * line height.
    *
    * Besides their size, items are specificed a @c vsize value that affects
    * how their final size and position are calculated. The possible values
    * are:
    * @li ascent: Item will be placed within the line's baseline and its
    * ascent. That is, the height between the line where all characters are
    * positioned and the highest point in the line. For @c size and @c absize
    * items, the descent value will be added to the total line height to make
    * them fit. @c relsize items will be adjusted to fit within this space.
    * @li full: Items will be placed between the descent and ascent, or the
    * lowest point in the line and its highest.
    *
    * The next image shows different configurations of items and how they
    * are the previously mentioned options affect their sizes. In all cases,
    * the green line indicates the ascent, blue for the baseline and red for
    * the descent.
    *
    * @image html entry_item.png
    * @image latex entry_item.eps width=\textwidth
    *
    * And another one to show how size differs from absize. In the first one,
    * the scale value is set to 1.0, while the second one is using one of 2.0.
    *
    * @image html entry_item_scale.png
    * @image latex entry_item_scale.eps width=\textwidth
    *
    * After the size for an item is calculated, the entry will request an
    * object to place in its space. For this, the functions set with
    * elm_entry_item_provider_append() and related functions will be called
    * in order until one of them returns a @c non-NULL value. If no providers
    * are available, or all of them return @c NULL, then the entry falls back
    * to one of the internal defaults, provided the name matches with one of
    * them.
    *
    * All of the following are currently supported:

    *
    * Alternatively, an item may reference an image by its path, using
    * the URI form @c file:///path/to/an/image.png and the entry will then
    * use that image for the item.
    *
    * @section entry-files Loading and saving files
    *
    * Entries have convinience functions to load text from a file and save
    * changes back to it after a short delay. The automatic saving is enabled
    * by default, but can be disabled with elm_entry_autosave_set() and files
    * can be loaded directly as plain text or have any markup in them
    * recognized. See elm_entry_file_set() for more details.
    *
    * @section entry-signals Emitted signals
    *
    * This widget emits the following signals:
    *
    * @li "changed": The text within the entry was changed.
    * @li "changed,user": The text within the entry was changed because of user interaction.
    * @li "activated": The enter key was pressed on a single line entry.

    * represented in comics.
    *
    * The bubble widget contains 5 important visual elements:
    * @li The frame is a rectangle with rounded rectangles and an "arrow".
    * @li The @p icon is an image to which the frame's arrow points to.
    * @li The @p label is a text which appears to the right of the icon if the
    * corner is "top_left" or "bottom_left" and is right aligned to the frame
    * otherwise.
    * @li The @p info is a text which appears to the right of the label. Info's
    * font is of a ligther color than label.
    * @li The @p content is an evas object that is shown inside the frame.
    *
    * The position of the arrow, icon, label and info depends on which corner is
    * selected. The four available corners are:
    * @li "top_left" - Default
    * @li "top_right"
    * @li "bottom_left"
    * @li "bottom_right"
    *
    * Signals that you can add callbacks for are:
    * @li "clicked" - This is called when a user has clicked the bubble.
    *
    * For an example of using a buble see @ref bubble_01_example_page "this".

    * Gesture Layer Usage:
    *
    * Use Gesture Layer to detect gestures.
    * The advantage is that you don't have to implement
    * gesture detection, just set callbacks of gesture state.
    * By using gesture layer we make standard interface.
    *
    * In order to use Gesture Layer you start with @ref elm_gesture_layer_add
    * with a parent object parameter.
    * Next 'activate' gesture layer with a @ref elm_gesture_layer_attach
    * call. Usually with same object as target (2nd parameter).
    *
    * Now you need to tell gesture layer what gestures you follow.
    * This is done with @ref elm_gesture_layer_cb_set call.
    * By setting the callback you actually saying to gesture layer:
    * I would like to know when the gesture @ref Elm_Gesture_Types
    * switches to state @ref Elm_Gesture_State.
    *
    * Next, you need to implement the actual action that follows the input
    * in your callback.
    *
    * Note that if you like to stop being reported about a gesture, just set
    * all callbacks referring this gesture to NULL.
    * (again with @ref elm_gesture_layer_cb_set)
    *
    * The information reported by gesture layer to your callback is depending
    * on @ref Elm_Gesture_Types:
    * @ref Elm_Gesture_Taps_Info is the info reported for tap gestures:
    * @ref ELM_GESTURE_N_TAPS, @ref ELM_GESTURE_N_LONG_TAPS,
    * @ref ELM_GESTURE_N_DOUBLE_TAPS, @ref ELM_GESTURE_N_TRIPLE_TAPS.
    *
    * @ref Elm_Gesture_Momentum_Info is info reported for momentum gestures:
    * @ref ELM_GESTURE_MOMENTUM.

    * Gesture Layer Tweaks:
    *
    * Note that line, flick, gestures can start without the need to remove fingers from surface.
    * When user fingers rests on same-spot gesture is ended and starts again when fingers moved.
    *
    * Setting glayer_continues_enable to false in @ref Config will change this behavior
    * so gesture starts when user touches (a *DOWN event) touch-surface
    * and ends when no fingers touches surface (a *UP event).

    * A list widget is a container whose children are displayed vertically or

    *
    * A list is a very simple type of list widget.  For more robust

    *
    * Smart callbacks one can listen to:
    * - @c "activated" - The user has double-clicked or pressed
    *   (enter|return|spacebar) on an item. The @c event_info parameter
    *   is the item that was activated.
    * - @c "clicked,double" - The user has double-clicked an item.
    *   The @c event_info parameter is the item that was double-clicked.
    * - "selected" - when the user selected an item
    * - "unselected" - when the user unselected an item
    * - "longpressed" - an item in the list is long-pressed
    * - "scroll,edge,top" - the list is scrolled until the top edge
    * - "scroll,edge,bottom" - the list is scrolled until the bottom edge
    * - "scroll,edge,left" - the list is scrolled until the left edge
    * - "scroll,edge,right" - the list is scrolled until the right edge

    * The slider adds a dragable “slider” widget for selecting the value of
    * something within a range.
    *
    * A slider can be horizontal or vertical. It can contain an Icon and has a
    * primary label as well as a units label (that is formatted with floating
    * point values and thus accepts a printf-style format string, like
    * “%1.2f units”. There is also an indicator string that may be somewhere
    * else (like on the slider itself) that also accepts a format string like
    * units. Label, Icon Unit and Indicator strings/objects are optional.
    *
    * A slider may be inverted which means values invert, with high vales being
    * on the left or top and low values on the right or bottom (as opposed to
    * normally being low on the left or top and high on the bottom and right).
    *
    * The slider should have its minimum and maximum values set by the
    * application with  elm_slider_min_max_set() and value should also be set by
    * the application before use with  elm_slider_value_set(). The span of the
    * slider is its length (horizontally or vertically). This will be scaled by
    * the object or applications scaling factor. At any point code can query the
    * slider for its value with elm_slider_value_get().
    *
    * Smart callbacks one can listen to:
    * - "changed" - Whenever the slider value is changed by the user.
    * - "slider,drag,start" - dragging the slider indicator around has started.
    * - "slider,drag,stop" - dragging the slider indicator around has stopped.
    * - "delay,changed" - A short time after the value is changed by the user.
    * This will be called only when the user stops dragging for
    * a very short period or when they release their
    * finger/mouse, so it avoids possibly expensive reactions to
    * the value change.
    *

    * @image latex img/widget/genlist/preview-00.eps
    * @image html img/genlist.png
    * @image latex img/genlist.eps
    *
    * This widget aims to have more expansive list than the simple list in
    * Elementary that could have more flexible items and allow many more entries
    * while still being fast and low on memory usage. At the same time it was
    * also made to be able to do tree structures. But the price to pay is more
    * complexity when it comes to usage. If all you want is a simple list with
    * icons and a single label, use the normal @ref List object.
    *
    * Genlist has a fairly large API, mostly because it's relatively complex,
    * trying to be both expansive, powerful and efficient. First we will begin
    * an overview on the theory behind genlist.
    *
    * @section Genlist_Item_Class Genlist item classes - creating items
    *
    * In order to have the ability to add and delete items on the fly, genlist
    * implements a class (callback) system where the application provides a
    * structure with information about that type of item (genlist may contain
    * multiple different items with different classes, states and styles).
    * Genlist will call the functions in this struct (methods) when an item is
    * "realized" (i.e., created dynamically, while the user is scrolling the
    * grid). All objects will simply be deleted when no longer needed with
    * evas_object_del(). The #Elm_Genlist_Item_Class structure contains the
    * following members:
    * - @c item_style - This is a constant string and simply defines the name
    *   of the item style. It @b must be specified and the default should be @c
    *   "default".
    * - @c mode_item_style - This is a constant string and simply defines the
    *   name of the style that will be used for mode animations. It can be left
    *   as @c NULL if you don't plan to use Genlist mode. See
    *   elm_genlist_item_mode_set() for more info.
    *
    * - @c func - A struct with pointers to functions that will be called when
    *   an item is going to be actually created. All of them receive a @c data
    *   parameter that will point to the same data passed to
    *   elm_genlist_item_append() and related item creation functions, and a @c
    *   obj parameter that points to the genlist object itself.
    *
    * The function pointers inside @c func are @c label_get, @c icon_get, @c
    * state_get and @c del. The 3 first functions also receive a @c part
    * parameter described below. A brief description of these functions follows:
    *
    * - @c label_get - The @c part parameter is the name string of one of the
    *   existing text parts in the Edje group implementing the item's theme.
    *   This function @b must return a strdup'()ed string, as the caller will
    *   free() it when done. See #Elm_Genlist_Item_Label_Get_Cb.
    * - @c icon_get - The @c part parameter is the name string of one of the
    *   existing (icon) swallow parts in the Edje group implementing the item's
    *   theme. It must return @c NULL, when no icon is desired, or a valid
    *   object handle, otherwise.  The object will be deleted by the genlist on
    *   its deletion or when the item is "unrealized".  See
    *   #Elm_Genlist_Item_Icon_Get_Cb.
    * - @c func.state_get - The @c part parameter is the name string of one of
    *   the state parts in the Edje group implementing the item's theme. Return
    *   @c EINA_FALSE for false/off or @c EINA_TRUE for true/on. Genlists will
    *   emit a signal to its theming Edje object with @c "elm,state,XXX,active"
    *   and @c "elm" as "emission" and "source" arguments, respectively, when
    *   the state is true (the default is false), where @c XXX is the name of
    *   the (state) part.  See #Elm_Genlist_Item_State_Get_Cb.
    * - @c func.del - This is intended for use when genlist items are deleted,
    *   so any data attached to the item (e.g. its data parameter on creation)
    *   can be deleted. See #Elm_Genlist_Item_Del_Cb.
    *
    * available item styles:
    * - default
    * - default_style - The text part is a textblock

    *
    * @section Genlist_Items Structure of items
    *
    * An item in a genlist can have 0 or more text labels (they can be regular
    * text or textblock Evas objects - that's up to the style to determine), 0
    * or more icons (which are simply objects swallowed into the genlist item's
    * theming Edje object) and 0 or more <b>boolean states</b>, which have the
    * behavior left to the user to define. The Edje part names for each of
    * these properties will be looked up, in the theme file for the genlist,
    * under the Edje (string) data items named @c "labels", @c "icons" and @c
    * "states", respectively. For each of those properties, if more than one
    * part is provided, they must have names listed separated by spaces in the
    * data fields. For the default genlist item theme, we have @b one label
    * part (@c "elm.text"), @b two icon parts (@c "elm.swalllow.icon" and @c
    * "elm.swallow.end") and @b no state parts.
    *
    * A genlist item may be at one of several styles. Elementary provides one
    * by default - "default", but this can be extended by system or application
    * custom themes/overlays/extensions (see @ref Theme "themes" for more
    * details).
    *
    * @section Genlist_Manipulation Editing and Navigating
    *
    * Items can be added by several calls. All of them return a @ref
    * Elm_Genlist_Item handle that is an internal member inside the genlist.
    * They all take a data parameter that is meant to be used for a handle to
    * the applications internal data (eg the struct with the original item
    * data). The parent parameter is the parent genlist item this belongs to if
    * it is a tree or an indexed group, and NULL if there is no parent. The
    * flags can be a bitmask of #ELM_GENLIST_ITEM_NONE,
    * #ELM_GENLIST_ITEM_SUBITEMS and #ELM_GENLIST_ITEM_GROUP. If
    * #ELM_GENLIST_ITEM_SUBITEMS is set then this item is displayed as an item
    * that is able to expand and have child items.  If ELM_GENLIST_ITEM_GROUP
    * is set then this item is group index item that is displayed at the top
    * until the next group comes. The func parameter is a convenience callback
    * that is called when the item is selected and the data parameter will be
    * the func_data parameter, obj be the genlist object and event_info will be
    * the genlist item.
    *
    * elm_genlist_item_append() adds an item to the end of the list, or if
    * there is a parent, to the end of all the child items of the parent.
    * elm_genlist_item_prepend() is the same but adds to the beginning of
    * the list or children list. elm_genlist_item_insert_before() inserts at
    * item before another item and elm_genlist_item_insert_after() inserts after
    * the indicated item.
    *
    * The application can clear the list with elm_genlist_clear() which deletes
    * all the items in the list and elm_genlist_item_del() will delete a specific
    * item. elm_genlist_item_subitems_clear() will clear all items that are
    * children of the indicated parent item.
    *
    * To help inspect list items you can jump to the item at the top of the list
    * with elm_genlist_first_item_get() which will return the item pointer, and
    * similarly elm_genlist_last_item_get() gets the item at the end of the list.
    * elm_genlist_item_next_get() and elm_genlist_item_prev_get() get the next
    * and previous items respectively relative to the indicated item. Using
    * these calls you can walk the entire item list/tree. Note that as a tree
    * the items are flattened in the list, so elm_genlist_item_parent_get() will
    * let you know which item is the parent (and thus know how to skip them if
    * wanted).
    *
    * @section Genlist_Muti_Selection Multi-selection
    *
    * If the application wants multiple items to be able to be selected,
    * elm_genlist_multi_select_set() can enable this. If the list is
    * single-selection only (the default), then elm_genlist_selected_item_get()
    * will return the selected item, if any, or NULL I none is selected. If the
    * list is multi-select then elm_genlist_selected_items_get() will return a
    * list (that is only valid as long as no items are modified (added, deleted,
    * selected or unselected)).
    *
    * @section Genlist_Usage_Hints Usage hints
    *
    * There are also convenience functions. elm_genlist_item_genlist_get() will
    * return the genlist object the item belongs to. elm_genlist_item_show()
    * will make the scroller scroll to show that specific item so its visible.
    * elm_genlist_item_data_get() returns the data pointer set by the item
    * creation functions.
    *
    * If an item changes (state of boolean changes, label or icons change),
    * then use elm_genlist_item_update() to have genlist update the item with
    * the new state. Genlist will re-realize the item thus call the functions
    * in the _Elm_Genlist_Item_Class for that item.
    *
    * To programmatically (un)select an item use elm_genlist_item_selected_set().
    * To get its selected state use elm_genlist_item_selected_get(). Similarly
    * to expand/contract an item and get its expanded state, use
    * elm_genlist_item_expanded_set() and elm_genlist_item_expanded_get(). And
    * again to make an item disabled (unable to be selected and appear
    * differently) use elm_genlist_item_disabled_set() to set this and
    * elm_genlist_item_disabled_get() to get the disabled state.
    *
    * In general to indicate how the genlist should expand items horizontally to
    * fill the list area, use elm_genlist_horizontal_set(). Valid modes are
    * ELM_LIST_LIMIT and ELM_LIST_SCROLL. The default is ELM_LIST_SCROLL. This
    * mode means that if items are too wide to fit, the scroller will scroll
    * horizontally. Otherwise items are expanded to fill the width of the
    * viewport of the scroller. If it is ELM_LIST_LIMIT, items will be expanded
    * to the viewport width and limited to that size. This can be combined with
    * a different style that uses edjes' ellipsis feature (cutting text off like
    * this: "tex...").
    *
    * Items will only call their selection func and callback when first becoming
    * selected. Any further clicks will do nothing, unless you enable always
    * select with elm_genlist_always_select_mode_set(). This means even if
    * selected, every click will make the selected callbacks be called.
    * elm_genlist_no_select_mode_set() will turn off the ability to select
    * items entirely and they will neither appear selected nor call selected
    * callback functions.
    *
    * Remember that you can create new styles and add your own theme augmentation
    * per application with elm_theme_extension_add(). If you absolutely must
    * have a specific style that overrides any theme the user or system sets up
    * you can use elm_theme_overlay_add() to add such a file.
    *
    * @section Genlist_Implementation Implementation
    *
    * Evas tracks every object you create. Every time it processes an event
    * (mouse move, down, up etc.) it needs to walk through objects and find out
    * what event that affects. Even worse every time it renders display updates,
    * in order to just calculate what to re-draw, it needs to walk through many
    * many many objects. Thus, the more objects you keep active, the more
    * overhead Evas has in just doing its work. It is advisable to keep your
    * active objects to the minimum working set you need. Also remember that
    * object creation and deletion carries an overhead, so there is a
    * middle-ground, which is not easily determined. But don't keep massive lists
    * of objects you can't see or use. Genlist does this with list objects. It
    * creates and destroys them dynamically as you scroll around. It groups them
    * into blocks so it can determine the visibility etc. of a whole block at
    * once as opposed to having to walk the whole list. This 2-level list allows
    * for very large numbers of items to be in the list (tests have used up to
    * 2,000,000 items). Also genlist employs a queue for adding items. As items
    * may be different sizes, every item added needs to be calculated as to its
    * size and thus this presents a lot of overhead on populating the list, this
    * genlist employs a queue. Any item added is queued and spooled off over
    * time, actually appearing some time later, so if your list has many members
    * you may find it takes a while for them to all appear, with your process
    * consuming a lot of CPU while it is busy spooling.
    *
    * Genlist also implements a tree structure, but it does so with callbacks to
    * the application, with the application filling in tree structures when
    * requested (allowing for efficient building of a very deep tree that could
    * even be used for file-management). See the above smart signal callbacks for
    * details.
    *
    * @section Genlist_Smart_Events Genlist smart events
    *
    * Signals that you can add callbacks for are:
    * - @c "activated" - The user has double-clicked or pressed
    *   (enter|return|spacebar) on an item. The @c event_info parameter is the
    *   item that was activated.
    * - @c "clicked,double" - The user has double-clicked an item.  The @c
    *   event_info parameter is the item that was double-clicked.
    * - @c "selected" - This is called when a user has made an item selected.
    *   The event_info parameter is the genlist item that was selected.
    * - @c "unselected" - This is called when a user has made an item
    *   unselected. The event_info parameter is the genlist item that was
    *   unselected.
    * - @c "expanded" - This is called when elm_genlist_item_expanded_set() is
    *   called and the item is now meant to be expanded. The event_info
    *   parameter is the genlist item that was indicated to expand.  It is the
    *   job of this callback to then fill in the child items.
    * - @c "contracted" - This is called when elm_genlist_item_expanded_set() is
    *   called and the item is now meant to be contracted. The event_info
    *   parameter is the genlist item that was indicated to contract. It is the
    *   job of this callback to then delete the child items.
    * - @c "expand,request" - This is called when a user has indicated they want
    *   to expand a tree branch item. The callback should decide if the item can
    *   expand (has any children) and then call elm_genlist_item_expanded_set()
    *   appropriately to set the state. The event_info parameter is the genlist
    *   item that was indicated to expand.
    * - @c "contract,request" - This is called when a user has indicated they
    *   want to contract a tree branch item. The callback should decide if the
    *   item can contract (has any children) and then call
    *   elm_genlist_item_expanded_set() appropriately to set the state. The
    *   event_info parameter is the genlist item that was indicated to contract.
    * - @c "realized" - This is called when the item in the list is created as a
    *   real evas object. event_info parameter is the genlist item that was
    *   created. The object may be deleted at any time, so it is up to the
    *   caller to not use the object pointer from elm_genlist_item_object_get()
    *   in a way where it may point to freed objects.
    * - @c "unrealized" - This is called just before an item is unrealized.
    *   After this call icon objects provided will be deleted and the item
    *   object itself delete or be put into a floating cache.
    * - @c "drag,start,up" - This is called when the item in the list has been
    *   dragged (not scrolled) up.
    * - @c "drag,start,down" - This is called when the item in the list has been
    *   dragged (not scrolled) down.
    * - @c "drag,start,left" - This is called when the item in the list has been
    *   dragged (not scrolled) left.
    * - @c "drag,start,right" - This is called when the item in the list has
    *   been dragged (not scrolled) right.
    * - @c "drag,stop" - This is called when the item in the list has stopped
    *   being dragged.
    * - @c "drag" - This is called when the item in the list is being dragged.
    * - @c "longpressed" - This is called when the item is pressed for a certain
    *   amount of time. By default it's 1 second.
    * - @c "scroll,anim,start" - This is called when scrolling animation has
    *   started.
    * - @c "scroll,anim,stop" - This is called when scrolling animation has
    *   stopped.
    * - @c "scroll,drag,start" - This is called when dragging the content has
    *   started.
    * - @c "scroll,drag,stop" - This is called when dragging the content has
    *   stopped.
    * - @c "scroll,edge,top" - This is called when the genlist is scrolled until
    *   the top edge.
    * - @c "scroll,edge,bottom" - This is called when the genlist is scrolled
    *   until the bottom edge.
    * - @c "scroll,edge,left" - This is called when the genlist is scrolled
    *   until the left edge.
    * - @c "scroll,edge,right" - This is called when the genlist is scrolled
    *   until the right edge.
    * - @c "multi,swipe,left" - This is called when the genlist is multi-touch
    *   swiped left.
    * - @c "multi,swipe,right" - This is called when the genlist is multi-touch
    *   swiped right.
    * - @c "multi,swipe,up" - This is called when the genlist is multi-touch
    *   swiped up.
    * - @c "multi,swipe,down" - This is called when the genlist is multi-touch
    *   swiped down.
    * - @c "multi,pinch,out" - This is called when the genlist is multi-touch
    *   pinched out.  "- @c multi,pinch,in" - This is called when the genlist is
    *   multi-touch pinched in.
    * - @c "swipe" - This is called when the genlist is swiped.

    * A genlist mode is a different way of selecting an item. Once a mode is
    * activated on an item, any other selected item is immediately unselected.
    * This feature provides an easy way of implementing a new kind of animation
    * for selecting an item, without having to entirely rewrite the item style
    * theme. However, the elm_genlist_selected_* API can't be used to get what
    * item is activate for a mode.
    *
    * The current item style will still be used, but applying a genlist mode to
    * an item will select it using a different kind of animation.
    *
    * The current active item for a mode can be found by
    * elm_genlist_mode_item_get().
    *
    * The characteristics of genlist mode are:
    * - Only one mode can be active at any time, and for only one item.
    * - Genlist handles deactivating other items when one item is activated.
    * - A mode is defined in the genlist theme (edc), and more modes can easily
    *   be added.
    * - A mode style and the genlist item style are different things. They
    *   can be combined to provide a default style to the item, with some kind
    *   of animation for that item when the mode is activated.
    *
    * When a mode is activated on an item, a new view for that item is created.
    * The theme of this mode defines the animation that will be used to transit
    * the item from the old view to the new view. This second (new) view will be
    * active for that item while the mode is active on the item, and will be

    * @brief Radio is a widget that allows for 1 or more options to be displayed
    * and have the user choose only 1 of them.
    *
    * A radio object contains an indicator, an optional Label and an optional
    * icon object. While it's possible to have a group of only one radio they,
    * are normally used in groups of 2 or more. To add a radio to a group use
    * elm_radio_group_add(). The radio object(s) will select from one of a set
    * of integer values, so any value they are configuring needs to be mapped to
    * a set of integers. To configure what value that radio object represents,
    * use  elm_radio_state_value_set() to set the integer it represents. To set
    * the value the whole group(which one is currently selected) is to indicate
    * use elm_radio_value_set() on any group member, and to get the groups value
    * use elm_radio_value_get(). For convenience the radio objects are also able
    * to directly set an integer(int) to the value that is selected. To specify
    * the pointer to this integer to modify, use elm_radio_value_pointer_set().
    * The radio objects will modify this directly. That implies the pointer must
    * point to valid memory for as long as the radio objects exist.

    *
    * A file selector is a widget that allows a user to navigate
    * through a file system, reporting file selections back via its
    * API.
    *
    * It contains shortcut buttons for home directory (@c ~) and to
    * jump one directory upwards (..), as well as cancel/ok buttons to
    * confirm/cancel a given selection. After either one of those two
    * former actions, the file selector will issue its @c "done" smart
    * callback.
    *
    * There's a text entry on it, too, showing the name of the current
    * selection. There's the possibility of making it editable, so it
    * is useful on file saving dialogs on applications, where one
    * gives a file name to save contents to, in a given directory in
    * the system. This custom file name will be reported on the @c
    * "done" smart callback (explained in sequence).
    *
    * Finally, it has a view to display file system items into in two
    * possible forms:
    * - list
    * - grid
    *
    * If Elementary is built with support of the Ethumb thumbnailing
    * library, the second form of view will display preview thumbnails
    * of files which it supports.
    *
    * Smart callbacks one can register to:
    *
    * - @c "selected" - the user has clicked on a file (when not in
    *      folders-only mode) or directory (when in folders-only mode)
    * - @c "directory,open" - the list has been populated with new
    *      content (@c event_info is a pointer to the directory's
    *      path, a @b stringshared string)
    * - @c "done" - the user has clicked on the "ok" or "cancel"
    *      buttons (@c event_info is a pointer to the selection's

    * A spinner is a widget which allows the user to increase or decrease
    * numeric values using arrow buttons, or edit values directly, clicking
    * over it and typing the new value.
    *
    * By default the spinner will not wrap and has a label
    * of "%.0f" (just showing the integer value of the double).
    *
    * A spinner has a label that is formatted with floating
    * point values and thus accepts a printf-style format string, like
    * “%1.2f units”.
    *
    * It also allows specific values to be replaced by pre-defined labels.
    *
    * Smart callbacks one can register to:
    *
    * - "changed" - Whenever the spinner value is changed.
    * - "delay,changed" - A short time after the value is changed by the user.
    *    This will be called only when the user stops dragging for a very short
    *    period or when they release their finger/mouse, so it avoids possibly
    *    expensive reactions to the value change.
    *
    * Available styles for it:
    * - @c "default";
    * - @c "vertical": up/down buttons at the right side and text left aligned.
    *

    * An index widget gives you an index for fast access to whichever
    * group of other UI items one might have. It's a list of text
    * items (usually letters, for alphabetically ordered access).
    *
    * Index widgets are by default hidden and just appear when the
    * user clicks over it's reserved area in the canvas. In its
    * default theme, it's an area one @ref Fingers "finger" wide on
    * the right side of the index widget's container.
    *
    * When items on the index are selected, smart callbacks get
    * called, so that its user can make other container objects to
    * show a given area or child object depending on the index item
    * selected. You'd probably be using an index together with @ref
    * List "lists", @ref Genlist "generic lists" or @ref Gengrid
    * "general grids".
    *
    * Smart events one  can add callbacks for are:
    * - @c "changed" - When the selected index item changes. @c
    *      event_info is the selected item's data pointer.
    * - @c "delay,changed" - When the selected index item changes, but
    *      after a small idling period. @c event_info is the selected
    *      item's data pointer.
    * - @c "selected" - When the user releases a mouse button and
    *      selects an item. @c event_info is the selected item's data
    *      pointer.
    * - @c "level,up" - when the user moves a finger from the first
    *      level to the second level
    * - @c "level,down" - when the user moves a finger from the second
    *      level to the first level
    *
    * The @c "delay,changed" event is so that it'll wait a small time

    *
    * Transit is designed to apply various animated transition effects to @c
    * Evas_Object, such like translation, rotation, etc. For using these
    * effects, create an @ref Elm_Transit and add the desired transition effects.
    *
    * Once the effects are added into transit, they will be automatically
    * managed (their callback will be called until the duration is ended, and
    * they will be deleted on completion).
    *
    * Example:
    * @code
    * Elm_Transit *trans = elm_transit_add();
    * elm_transit_object_add(trans, obj);
    * elm_transit_effect_translation_add(trans, 0, 0, 280, 280
    * elm_transit_duration_set(transit, 1);
    * elm_transit_auto_reverse_set(transit, EINA_TRUE);
    * elm_transit_tween_mode_set(transit, ELM_TRANSIT_TWEEN_MODE_DECELERATE);
    * elm_transit_repeat_times_set(transit, 3);
    * @endcode
    *
    * Some transition effects are used to change the properties of objects. They
    * are:
    * @li @ref elm_transit_effect_translation_add
    * @li @ref elm_transit_effect_color_add
    * @li @ref elm_transit_effect_rotation_add
    * @li @ref elm_transit_effect_wipe_add
    * @li @ref elm_transit_effect_zoom_add
    * @li @ref elm_transit_effect_resizing_add
    *
    * Other transition effects are used to make one object disappear and another
    * object appear on its old place. These effects are:
    *
    * @li @ref elm_transit_effect_flip_add
    * @li @ref elm_transit_effect_resizable_flip_add
    * @li @ref elm_transit_effect_fade_add
    * @li @ref elm_transit_effect_blend_add
    *
    * It's also possible to make a transition chain with @ref
    * elm_transit_chain_transit_add.
    *
    * @warning We strongly recommend to use elm_transit just when edje can not do
    * the trick. Edje has more advantage than Elm_Transit, it has more flexibility and
    * animations can be manipulated inside the theme.
    *
