+ /**
+ * @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
+ * until the right edge.
