@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 which hold the widgets.

@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 (hello) and title (Hello)
   win = elm_win_util_standard_add("hello", "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 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

    * @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 that 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"

    * 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:

    * 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:

   /* box */
   /**
    * @defgroup Box Box
    *
    * 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.
    *

    * 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

    * @li slide_bounce - The text appears in the left of the label and slides to

    * In this example we are going to create 4 Frames with different styles and

    *
    * We start we the usual setup code:
    * @until show(bg)
    *
    * And then create one rectangle:
    * @until show
    *
    * To add it in our first frame, which since it doesn't have it's style
    * specifically set uses the default style:
    * @until show
    *
    * And then create another rectangle:
    * @until show
    *
    * To add it in our second frame, which uses the "pad_small" style, note that
    * even tough we are setting a text for this frame it won't be show, only the
    * default style shows the Frame's title:
    * @until show
    * @note The "pad_small", "pad_medium", "pad_large" and "pad_huge" styles are
    * very similar, their only difference is the size of the empty area around
    * the content of the frame.
    *
    * And then create yet another rectangle:
    * @until show
    *
    * To add it in our third frame, which uses the "outdent_top" style, note
    * that even tough we are setting a text for this frame it won't be show,
    * only the default style shows the Frame's title:
    * @until show
    *
    * And then create one last rectangle:
    * @until show
    *
    * To add it in our fourth and final frame, which uses the "outdent_bottom"
    * style, note that even tough we are setting a text for this frame it won't
    * be show, only the default style shows the Frame's title:

   /**
    * @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
    *
    * Gengrid 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
    * #GridItemLabelGetFunc.
    * - @c func.content_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 (content) swallow parts in the Edje group implementing the
    * item's theme. It must return @c NULL, when no content 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 #GridItemIconGetFunc.
    * - @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 #GridItemStateGetFunc.
    * - @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 #GridItemDelFunc.
    *
    * @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 content 
    * 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.
    * - @c "edge,top" - This is called when the gengrid is scrolled until
    *   the top edge.
    * - @c "edge,bottom" - This is called when the gengrid is scrolled
    *   until the bottom edge.
    * - @c "edge,left" - This is called when the gengrid is scrolled
    *   until the left edge.
    * - @c "edge,right" - This is called when the gengrid is scrolled

    * 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_object_content_set/get/unset 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_object_content_part_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

    *
    * 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.

    * Anchorview is for displaying text that contains markup with anchors
    * like <c>\<a href=1234\>something\</\></c> in it.
    *
    * Besides being styled differently, the anchorview widget provides the
    * necessary functionality so that clicking on these anchors brings up a
    * popup with user defined content such as "call", "add to contacts" or
    * "open web page". This popup is provided using the @ref Hover widget.
    *
    * This widget is very similar to @ref Anchorblock, so refer to that
    * widget for an example. The only difference Anchorview has is that the
    * widget is already provided with scrolling functionality, so if the
    * text set to it is too large to fit in the given space, it will scroll,
    * whereas the @ref Anchorblock widget will keep growing to ensure all the
    * text can be displayed.
    *
    * This widget emits the following signals:
    * @li "anchor,clicked": will be called when an anchor is clicked. The
    * @p event_info parameter on the callback will be a pointer of type
    * ::Elm_Entry_Anchorview_Info.
    *
    * See @ref Anchorblock for an example on how to use both of them.

    * Anchorblock is for displaying text that contains markup with anchors
    * like <c>\<a href=1234\>something\</\></c> in it.
    *
    * Besides being styled differently, the anchorblock widget provides the
    * necessary functionality so that clicking on these anchors brings up a
    * popup with user defined content such as "call", "add to contacts" or
    * "open web page". This popup is provided using the @ref Hover widget.
    *
    * This widget emits the following signals:
    * @li "anchor,clicked": will be called when an anchor is clicked. The
    * @p event_info parameter on the callback will be a pointer of type
    * ::Elm_Entry_Anchorblock_Info.
    *
    * @see Anchorview
    * @see Entry
    * @see Hover

   /**
    * @page tutorial_anchorblock_example Anchorblock/Anchorview example
    * This exampel will show both Anchorblock and @ref Anchorview,
    * since both are very similar and it's easier to show them once and side
    * by side, so the difference is more clear.
    *
    * We'll show the relevant snippets of the code here, but the full example
    * can be found here... sorry, @ref anchorblock_example_01.c "here".
    *
    * As for the actual example, it's just a simple window with an anchorblock
    * and an anchorview, both containing the same text. After including
    * Elementary.h and declaring some functions we'll need, we jump to our
    * elm_main (see ELM_MAIN) and create our window.
    * @dontinclude anchorblock_example_01.c
    * @skip int
    * @until const char
    * @until ;
    *
    * With the needed variables declared, we'll create the window and a box to
    * hold our widgets, but we don't need to go through that here.
    *
    * In order to make clear where the anchorblock ends and the anchorview
    * begins, they'll be each inside a @ref Frame. After creating the frame,
    * the anchorblock follows.
    * @skip elm_frame_add
    * @until elm_frame_content_set
    *
    * Nothing out of the ordinary there. What's worth mentioning is the call
    * to elm_anchorblock_hover_parent_set(). We are telling our widget that
    * when an anchor is clicked, the hover for the popup will cover the entire
    * window. This affects the area that will be obscured by the hover and
    * where clicking will dismiss it, as well as the calculations it does to
    * inform the best locations where to insert the popups content.
    * Other than that, the code is pretty standard. We also need to set our
    * callback for when an anchor is clicked, since it's our task to populate
    * the popup. There's no default for it.
    *
    * The anchorview is no different, we only change a few things so it looks
    * different.
    * @until elm_frame_content_set
    *
    * Then we run, so stuff works and close our main function in the usual way.
    * @until ELM_MAIN
    *
    * Now, a little note. Normally you would use either one of anchorblock or
    * anchorview, set your one callback to clicks and do your stuff in there.
    * In this example, however, there are a few tricks to make it easier to
    * show both widgets in one go (and to save me some typing). So we have
    * two callbacks, one per widget, that will call a common function to do
    * the rest. The trick is using ::Elm_Entry_Anchorblock_Info for the
    * anchorview too, since both are equal, and passing a callback to use
    * for our buttons to end the hover, because each widget has a different
    * function for it.
    * @until _anchorview_clicked_cb
    * @until }
    *
    * The meat of our popup is in the following function. We check what kind
    * of menu we need to show, based on the name set to the anchor in the
    * markup text. If there's no type (something went wrong, no valid contact
    * in the address list) we are just putting a button that does nothing, but
    * it's perfectly reasonable to just end the hover and call it quits.
    *
    * Our popup will consist of one main button in the middle of our hover,
    * and possibly a secondary button and a list of other options. We'll create
    * first our main button and check what kind of popup we need afterwards.
    * @skip static void
    * @skip static void
    * @until eina_stringshare_add
    * @until }
    *
    * Each button has two callbacks, one is our hack to close the hover
    * properly based on which widget it belongs to, the other a simple
    * printf that will show the action with the anchors own data. This is
    * not how you would usually do it. Instead, the common case is to have
    * one callback for the button that will know which function to call to end
    * things, but since we are doing it this way it's worth noting that
    * smart callbacks will be called in reverse in respect to the order they
    * were added, and since our @c btn_end_cb will close the hover, and thus
    * delete our buttons, the other callback wouldn't be called if we had
    * added it before.
    *
    * After our telephone popup, there are a few others that are practically
    * the same, so they won't be shown here.
    *
    * Once we are done with that, it's time to place our actions into our
    * hover. Main button goes in the middle without much questioning, and then
    * we see if we have a secondary button and a box of extra options.
    * Because I said so, secondary button goes on either side and box of
    * options either on top or below the main one, but to choose which
    * exactly, we use the hints our callback info has, which saves us from
    * having to do the math and see which side has more space available, with
    * a little special case where we delete our extra stuff if there's nowhere
    * to place it.
    * @skip url:
    * @skip }
    * @skip evas_object_smart
    * @until evas_object_del(box)
    * @until }
    * @until }

    * represented in comics.
    *
    * The bubble widget contains 5 important visual elements:
    * @li The frame is a rectangle with rounded edjes 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".

    * A actionslider is a switcher for 2 or 3 labels with customizable magnet
    * properties. The indicator is the element the user drags to choose a label.
    * When the position is set with magnet, when released the indicator will be
    * moved to it if it's nearest the magnetized position.
    *
    * @note By default all positions are set as enabled.
    *
    * Signals that you can add callbacks for are:
    *
    * "selected" - when user selects an enabled position (the label is passed
    *              as event info)".
    * @n
    * "pos_changed" - when the indicator reaches any of the positions("left",
    *                 "right" or "center").

    * This example will show 2 checkboxes, one with just a label and the second
    * one with both a label and an icon. This example also ilustrates how to
    * have the checkbox change the value of a variable and how to react to those
    * changes.
    *
    * We will start with the usual setup code:
    * @until show(bg)
    *
    * And now we create our first checkbox, set its label, tell it to change
    * the value of @p value when the checkbox stats is changed and ask to be
    * notified of state changes:
    * @until show
    *
    * For our second checkbox we are going to set an icon so we need to create
    * and icon:
    * @until show
    * @note For simplicity we are using a rectangle as icon, but any evas object
    * can be used.
    *
    * And for our second checkbox we set the label, icon and state to true:
    * @until show
    *
    * We now do some more setup:
    * @until ELM_MAIN
    *
    * And finally implement the callback that will be called when the first
    * checkbox's state changes. This callback will use @p data to print a
    * message:
    * @until }
    * @note This work because @p data is @p value(from the main function) and @p
    * value is changed when the checkbox is changed.
    *
    * Our example will look like this:
    * @image html screenshots/check_example_01.png
    * @image latex screenshots/check_example_01.eps
    *
    * @example check_example_01.c

    * can set a pointer to a boolean directly with elm_check_state_pointer_set()
    * for it to modify.

    *             the check object(event_info is NULL).

    * Smart callbacks one can register to:
    * - @c "selected" - when the widget's selected text item is changed
    * - @c "overflowed" - when the widget's current selection is changed
    *   from the first item in its list to the last
    * - @c "underflowed" - when the widget's current selection is changed
    *   from the last item in its list to the first

    * @defgroup Transit Transit
    * @ingroup Elementary
    *
    * 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.
    *
    * List of examples:
    * @li @ref transit_example_01_explained
    * @li @ref transit_example_02_explained
    * @li @ref transit_example_03_c
    * @li @ref transit_example_04_c

    * @defgroup Naviframe Naviframe
    *
    * @brief Naviframe is a kind of view manager for the applications.
    *
    * Naviframe provides functions to switch different pages with stack
    * mechanism. It means if one page(item) needs to be changed to the new one,
    * then naviframe would push the new page to it's internal stack. Of course,
    * it can be back to the previous page by popping the top page. Naviframe
    * provides some transition effect while the pages are switching (same as
    * pager).
    *
    * Since each item could keep the different styles, users could keep the
    * same look & feel for the pages or different styles for the items in it's
    * application.
    *
    * Signals that you can add callback for are:
    *
    * @li "transition,finished" - When the transition is finished in changing
    *     the item
    * @li "title,clicked" - User clicked title area
    *
    * Default contents parts for the naviframe items that you can use for are:
    *
    * @li "elm.swallow.content" - The main content of the page
    * @li "elm.swallow.prev_btn" - The button to go to the previous page
    * @li "elm.swallow.next_btn" - The button to go to the next page
    *
