@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.

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

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,
aslisted in the Authors section above.

    *
    * @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

    *        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"
    *
    * @{

   /**
    * @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.
    *

   /**
    * @defgroup Anchorview Anchorview
    *
    * 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

   /**
    * @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 }

   /** Signals that you can add callbacks for are:
    * "clicked,double" - This is called when a user has double-clicked an item.
    *                    The event_info parameter is the genlist item that was
    *                    double-clicked.
    * "selected" - This is called when a user has made an item selected. The
    *              event_info parameter is the genlist item that was selected.
    * "unselected" - This is called when a user has made an item unselected. The
    *                 event_info parameter is the genlist item that was
    *                 unselected.
    * "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.
    * "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.
    * "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.
    * "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.
    * "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.
    * "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.
    * "drag,start,up" - This is called when the item in the list has been
    *                   dragged (not scrolled) up.
    * "drag,start,down" - This is called when the item in the list has been
    *                     dragged (not scrolled) down.
    * "drag,start,left" - This is called when the item in the list has been
    *                     dragged (not scrolled) left.
    * "drag,start,right" - This is called when the item in the list has been
    *                      dragged (not scrolled) right.
    * "drag,stop" - This is called when the item in the list has stopped being
    *               dragged.
    * "drag" - This is called when the item in the list is being dragged.
    * "longpressed" - This is called when the item is pressed for a certain
    *                 amount of time. By default it's 1 second.
    * "scroll,edge,top" - This is called when the genlist is scrolled until the
    *                     top edge.
    * "scroll,edge,bottom" - This is called when the genlist is scrolled until
    *                        the bottom edge.
    * "scroll,edge,left" - This is called when the genlist is scrolled until the
    *                      left edge.
    * "scroll,edge,right" - This is called when the genlist is scrolled until
    *                       the right edge.
    * "multi,swipe,left" - This is called when the genlist is multi-touch swiped
    *                       left.
    * "multi,swipe,right" - This is called when the genlist is multi-touch
    *                       swiped right.

    * @brief Functions to ease creation of animations.
    *
    * elm_animator is designed to provide an easy way to create animations.
    * Creating an animation with elm_animator is as simple as setting a
    * duration, an operating callback and telling it to run the animation.
    * However that is not the full extent of elm_animator's ability, animations
    * can be paused and resumed, reversed and the animation need not be linear.
    *
    * To run an animation you must specify at least a duration and operation
    * callback, not setting any other properties will create a linear animation
    * that runs once and is not reversed.
    *
    * @ref elm_animator_example_page_01 "This" example should make all of that
    * very clear.
    *
    * @warning elm_animator is @b not a widget.

    * @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
