+/**
+ * @defgroup Grid Scrolled Grid
+ *
+ * This widget aims to position objects in a grid layout while actually
+ * building only the visible ones, using the same idea as genlist: the user
+ * define a class for each cell, specifying functions that will be called at
+ * object creation and deletion.
+ *
+ * Signals that you can add callbacks for are:
+ *
+ * clicked - The user has double-clicked a cell. The event_info parameter is
+ * the grid cell that was double-clicked.
+ *
+ * selected - The user has made an item selected. The event_info parameter is
+ * the grid cell that was selected.
+ *
+ * unselected - The user has made an item unselected. The event_info parameter
+ * is the grid cell that was unselected.
+ *
+ * realized - This is called when the cell in the grid is created as a real
+ * evas object. event_info is the grid cell 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_scrolled_grid_cell_object_get() in a way where it may point to
+ * freed objects.
+ *
+ * drag,start,up - Called when the cell in the grid has been dragged (not
+ * scrolled) up.
+ *
+ * drag,start,down - Called when the cell in the grid has been dragged (not
+ * scrolled) down.
+ *
+ * drag,start,left - Called when the cell in the grid has been dragged (not
+ * scrolled) left.
+ *
+ * drag,start,right - Called when the cell in the grid has been dragged (not
+ * scrolled) right.
+ *
+ * drag,stop - Called when the cell in the grid has stopped being dragged.
+ *
+ * drag - Called when the cell in the grid is being dragged.
+ *
+ * scroll - called when the content has been scrolled (moved).
+ *
+ * scroll,drag,start - called when dragging the content has started.
+ *
+ * scroll,drag,stop - called when dragging the content has stopped.
+ *
+ *
+ * A cell in the grid can have 0 or more text labels (they can be regular text
+ * or textblock - that's up to the style to determine), 0 or more icons (which
+ * are simply objects swallowed into the grid cell) and 0 or more boolean states
+ * that can be used for check, radio or other indicators by the edje theme style.
+ * A cell may be one of several styles (Elementary provides 1 by default -
+ * "default", but this can be extended by system or application custom
+ * themes/overlays/extensions).
+ *
+ * In order to implement the ability to add and delete cells on the fly, Grid
+ * implements a class/callback system where the application provides a structure
+ * with information about that type of cell (grid may contain multiple different
+ * cells with different classes, states and styles). Grid will call the functions
+ * in this struct (methods) when a cell is "realized" (that is created
+ * dynamically while scrolling). All objects will simply be deleted when no
+ * longer needed with evas_object_del(). The Elm_Genlist_Item_Class structure
+ * contains the following members:
+ *
+ * cell_style - This is a constant string and simply defines the name of the
+ * cell style. It must be specified and the default should be "default".
+ *
+ * func.label_get - This function is called when an actual cell object is
+ * created. The data parameter is the one passed to elm_scrolled_grid_cell_add()
+ * and related cell creation functions. The obj parameter is the grid object and
+ * the part parameter is the string name of the text part in the edje design that
+ * is listed as one of the possible labels that can be set. This function must
+ * return a strdup'()ed string as the caller will free() it when done.
+ *
+ * func.icon_get - This function is called when an actual item object is
+ * created. The data parameter is the one passed to elm_scrolled_grid_cell_add()
+ * and related cell creation functions. The obj parameter is the grid object and
+ * the part parameter is the string name of the icon part in the edje design that
+ * is listed as one of the possible icons that can be set. This must return NULL
+ * for no object or a valid object. The object will be deleted by grid on
+ * shutdown or when the cell is unrealized.
+ *
+ * func.state_get - This function is called when an actual cell object is
+ * created. The data parameter is the one passed to elm_scrolled_grid_cell_add()
+ * and related cell creation functions. The obj parameter is the grid object and
+ * the part parameter is the string name of th state part in the edje design that
+ * is listed as one of the possible states that can be set. Return 0 for false
+ * and 1 for true. Grid will emit a signal to the edje object with
+ * "elm,state,XXX,active" "elm" when true (the default is false), where XXX is
+ * the name of the part.
+ *
+ * func.del - This is called when elm_scrolled_grid_cell_del() is called on a
+ * cell or elm_scrolled_grid_clear() is called on the grid. This is intended for
+ * use when actual grid cells are deleted, so any backing data attached to the
+ * cell (e.g. its data parameter on creation) can be deleted.
+ *
+ * If the application wants multiple cells to be able to be selected,
+ * elm_scrolled_grid_multi_select_set() can enable this. If the grid is
+ * single-selection only (the default), then elm_scrolled_grid_select_cell_get()
+ * will return the selected cell, if any, or NULL if none is selected. If the
+ * grid is multi-select then elm_scrolled_grid_selected_cells_get() will return a
+ * list (that is only valid as long as no cells are modified (added, deleted,
+ * selected or unselected).
+ *
+ * If a cell changes (state of boolean changes, label or icons change), then use
+ * elm_scrolled_grid_cell_update() to have grid update the cell with the new
+ * state. Grid will re-realize the cell thus call the functions in the
+ * _Elm_Grid_Cell_Class for that cell.
+ *
+ * To programmatically (un)select a cell use elm_scrolled_grid_cell_selected_set().
+ * To get its selected state use elm_scrolled_grid_cell_selected_get(). To make a
+ * cell disabled (unable to be selected and appear differently) use
+ * elm_scrolled_grid_cell_disable_set() to set this and
+ * elm_scrolled_grid_cell_disable_get() to get the disabled state.
+ *
+ * Cells will only call their selection func and callback when first becoming
+ * selected. Any further clicks will do nothing, unless you enable always
+ * select with elm_scrolled_grid_always_select_mode_set(). This means event if
+ * selected, every click will make the selected callbacks be called.
+ * elm_scrolled_grid_no_select_mode_set() will turn off the ability to select
+ * items entirely and they will neither appear selected nor call selected
+ * callback function.
+ *
+ * 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.
+ *
+ * --
+ * TODO:
+ * * Handle non-homogeneous objects too.
