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 genlist: the user defines a 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.

This widget inherits from the Layout one, so that all the functions acting on it also work for gengrid objects.

This widget implements the elm-scrollable-interface interface, so that all (non-deprecated) functions for the base Scroller widget also work for gengrids.

Some calls on the gengrid's API are marked as deprecated, as they just wrap the scrollable widgets counterpart functions. Use the ones we point you to, for each case of deprecation here, instead -- eventually the deprecated ones will be discarded (next major release).

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 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 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).

Gengrid items

An item in a gengrid can have 0 or more texts (they can be regular text or textblock Evas objects - that's up to the style to determine), 0 or more contents (which are simply objects swallowed into the gengrid item's theming Edje object) and 0 or more boolean states, 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 "texts", "contents" and "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 one text part ("elm.text"), two content parts ("elm.swalllow.icon" and "elm.swallow.end") and 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 themes for more details).

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:

item_style - This is a constant string and simply defines the name of the item style. It must be specified and the default should be "default".
func.text_get - This function is called when an item object is actually created. The data parameter will point to the same data passed to elm_gengrid_item_append() and related item creation functions. The obj parameter is the gengrid object itself, while the part one is the name string of one of the existing text parts in the Edje group implementing the item's theme. This function must return a strdup'()ed string, as the caller will free() it when done. See #Elm_Gengrid_Item_Text_Get_Cb.
func.content_get - This function is called when an item object is actually created. The data parameter will point to the same data passed to elm_gengrid_item_append() and related item creation functions. The obj parameter is the gengrid object itself, while the 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 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 #Elm_Gengrid_Item_Content_Get_Cb.
func.state_get - This function is called when an item object is actually created. The data parameter will point to the same data passed to elm_gengrid_item_append() and related item creation functions. The obj parameter is the gengrid object itself, while the part one is the name string of one of the state parts in the Edje group implementing the item's theme. Return EINA_FALSE for false/off or EINA_TRUE for true/on. Gengrids will emit a signal to its theming Edje object with "elm,state,xxx,active" and "elm" as "emission" and "source" arguments, respectively, when the state is true (the default is false), where xxx is the name of the (state) part. See #Elm_Gengrid_Item_State_Get_Cb.
func.del - This is called when elm_object_item_del() is called on an item or elm_gengrid_clear() is called on the gengrid. This is intended for use when gengrid items are deleted, so any data attached to the item (e.g. its data parameter on creation) can be deleted. See #Elm_Gengrid_Item_Del_Cb.

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 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, text 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_object_item_disabled_set() to set this and elm_object_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_select_mode_set() as ELM_OBJECT_SELECT_MODE_ALWAYS, thus making every click to issue selection callbacks. elm_gengrid_select_mode_set() as ELM_OBJECT_SELECT_MODE_NONE 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.

Gengrid smart events

This widget emits the following signals, besides the ones sent from Layout:

"activated" - The user has double-clicked or pressed (enter|return|spacebar) on an item. The event_info parameter is the gengrid item that was activated.
"pressed" - The user pressed the an item. The event_info parameter is the item that was pressed.

"index,update" - This is called when a gengrid item index is changed. Note that this callback is called while each item is being realized.
"highlighted" - an item in the list is highlighted. This is called when the user presses an item or keyboard selection is done so the item is physically highlighted. The event_info parameter is the item that was highlighted.
"unhighlighted" - an item in the list is unhighlighted. This is called when the user releases an item or keyboard selection is moved so the item is physically unhighlighted. The event_info parameter is the item that was unhighlighted.

Since :: 2.3

Parameters:

[in] it a gengrid item

Returns:: EINA_TRUE, if cursors are being looked for only on those provided by the rendering engine, EINA_FALSE if they are being searched on the widget's theme, as well.

Since :: 2.3

Parameters:

[in]	it	gengrid item to customize cursor on
[in]	cursor	the cursor type's name

Remarks:: This function works analogously as elm_object_cursor_set(), but here the cursor's changing area is restricted to the item's area, and not the whole widget's. Note that that item cursors have precedence over widget cursors, so that a mouse over item will always show cursor type.; If this function is called twice for an object, a previously set cursor will be unset on the second call.

See also:: elm_object_cursor_set(); elm_gengrid_item_cursor_get(); elm_gengrid_item_cursor_unset()

Warning:: Before you set a cursor style you should have defined a custom cursor previously on the item, with elm_gengrid_item_cursor_set()

See also:: elm_gengrid_item_cursor_engine_only_set(); elm_gengrid_item_cursor_style_get()

void elm_gengrid_item_cursor_unset ( Elm_Object_Item * it )

This function works analogously as elm_object_tooltip_style_set(), but here applied only to gengrid item objects. The default style for tooltips is "default".; before you set a style you should define a tooltip with elm_gengrid_item_tooltip_content_cb_set() or elm_gengrid_item_tooltip_text_set()

See also:: elm_gengrid_item_tooltip_style_get()

void elm_gengrid_item_tooltip_text_set	(	Elm_Object_Item *	it,

It can have only one tooltip at a time, so any previous tooltip data will get removed.; In order to set a content or something else as a tooltip, look at elm_gengrid_item_tooltip_content_cb_set().

void elm_gengrid_item_tooltip_unset ( Elm_Object_Item * it )

Unset a tooltip from a given gengrid item.

Since :: 2.3

Parameters:

[in] it gengrid item to remove a previously set tooltip from.

Remarks:: This call removes any tooltip set on item. The callback provided as del_cb to elm_gengrid_item_tooltip_content_cb_set() will be called to notify it is not used anymore (and have resources cleaned, if need be).

See also:: elm_gengrid_item_tooltip_content_cb_set()

Eina_Bool elm_gengrid_item_tooltip_window_mode_get ( const Elm_Object_Item * it )

Get size restriction state of an object's tooltip.

Since :: 2.3

Parameters:

[in] it The tooltip's anchor object

Returns:: If EINA_TRUE, size restrictions are disabled

Remarks:: This function returns whether a tooltip is allowed to expand beyond its parent window's canvas. It will instead be limited only by the size of the display.

Eina_Bool elm_gengrid_item_tooltip_window_mode_set	(	Elm_Object_Item *	it,
		Eina_Bool	disable
	)

Disable size restrictions on an object's tooltip.

Since :: 2.3

Parameters:

[in]	it	The tooltip's anchor object
[in]	disable	If `EINA_TRUE`, size restrictions are disabled

Returns:: EINA_FALSE on failure, EINA_TRUE on success

Remarks:: This function allows a tooltip to expand beyond its parent window's canvas. It will instead be limited only by the size of the display.

void elm_gengrid_item_update ( Elm_Gengrid_Item * obj )

Update the contents of a given gengrid item.

Since :: 2.3

Remarks:: This updates an item by calling all the item class functions again to get the contents, texts and states. Use this when the original item data has changed and you want the changes to be reflected.

Parameters:

[in] obj The elm gengrid item object

unsigned int elm_gengrid_items_count ( const Elm_Gengrid * obj )

Return how many items are currently in a list.

Since :: 2.3

Returns:: The total number of list items in the list

Remarks:: This behavior is O(1) and includes items which may or may not be realized.

Parameters:

[in] obj The elm gengrid object

Elm_Object_Item* elm_gengrid_last_item_get ( const Elm_Gengrid * obj )

Get the last item in a given gengrid widget.

Since :: 2.3

Returns:: The last item's handle or NULL, if there are no items in obj (and on errors)

Remarks:: This returns the last item in the obj's internal list of items.

See also:: elm_gengrid_first_item_get()

Parameters:

[in] obj The elm gengrid object

Eina_Bool elm_gengrid_multi_select_get ( const Elm_Gengrid * obj )

Get whether multi-selection is enabled or disabled for a given gengrid widget.

Since :: 2.3

Returns:: EINA_TRUE, if multi-selection is enabled, EINA_FALSE otherwise

See also:: elm_gengrid_multi_select_set() for more details

[in] obj The elm gengrid object

void elm_gengrid_multi_select_set	(	Elm_Gengrid *	obj,
		Eina_Bool	multi
	)

Enable or disable multi-selection in a given gengrid widget.

Since :: 2.3

Remarks:: Multi-selection is the ability to have more than one item selected, on a given gengrid, simultaneously. When it is enabled, a sequence of clicks on different items will make them all selected, progressively. A click on an already selected item will unselect it. If interacting via the keyboard, multi-selection is enabled while holding the "Shift" key.; By default, multi-selection is disabled on gengrids

See also:: elm_gengrid_multi_select_get()

Parameters:

[in]	obj	The elm gengrid object
[in]	multi	`EINA_TRUE`, to enable multi-selection, `EINA_FALSE` to disable it.

		unsigned int	nth
	)

Get the nth item, in a given gengrid widget, placed at position nth, in its internal items list

Parameters:

obj	The gengrid object
nth	The number of the item to grab (0 being the first)

Returns:: The item stored in obj at position nth or NULL, if there's no item with that index (and on errors)

Since (EFL) :: 1.8

EINA_DEPRECATED void elm_gengrid_page_show	(	const Evas_Object *	obj,
		int	h_pagenumber,
		int	v_pagenumber

Since :: 2.3

Parameters:

[in]	obj	The gengrid object
[in]	h_pagenumber	The horizontal page number
[in]	v_pagenumber	The vertical page number

Remarks:: 0, 0 of the indicated page is located at the top-left of the viewport. This will jump to the page directly without animation.; Example of usage:

 sc = elm_gengrid_add(win);
 elm_gengrid_content_set(sc, content);
 elm_gengrid_page_relative_set(sc, 1, 0);
 elm_gengrid_current_page_get(sc, &h_page, &v_page);
 elm_gengrid_page_show(sc, h_page + 1, v_page);

Deprecated:: Use elm_scroller_page_show() instead. Deprecated since Tizen 2.4

See also:: elm_scroller_page_bring_in()

Eina_List* elm_gengrid_realized_items_get ( const Elm_Gengrid * obj )

Get a list of realized items in gengrid.

Since :: 2.3

Returns:: The list of realized items, nor NULL if none are realized.

Remarks:: This returns a list of the realized items in the gengrid. The list contains gengrid item pointers. The list must be freed by the caller when done with eina_list_free(). The item pointers in the list are only valid so long as those items are not deleted or the gengrid is not deleted.

See also:: elm_gengrid_realized_items_update()

Parameters:

[in] obj The elm gengrid object

void elm_gengrid_realized_items_update ( Elm_Gengrid * obj )

Update the contents of all realized items.

Since :: 2.3

Remarks:: This updates all realized items by calling all the item class functions again to get the contents, texts and states. Use this when the original item data has changed and the changes are desired to be reflected.; To update just one item, use elm_gengrid_item_update().

See also:: elm_gengrid_realized_items_get(); elm_gengrid_item_update()

Parameters:

[in] obj The elm gengrid object

Eina_Bool elm_gengrid_reorder_mode_get ( const Elm_Gengrid * obj )

Get whether a given gengrid widget is or not able have items.

Since :: 2.3

reordered

Returns:: EINA_TRUE, if reordering is on, EINA_FALSE if it's off

See also:: elm_gengrid_reorder_mode_set() for more details

Parameters:

[in] obj The elm gengrid object

void elm_gengrid_reorder_mode_set	(	Elm_Gengrid *	obj,
		Eina_Bool	reorder_mode
	)

Set whether a given gengrid widget is or not able have items.

Since :: 2.3

reordered

Remarks:: If a gengrid is set to allow reordering, a click held for more than 0.5 over a given item will highlight it specially, signaling the gengrid has entered the reordering state. From that time on, the user will be able to, while still holding the mouse button down, move the item freely in the gengrid's viewport, replacing to said item to the locations it goes to. The replacements will be animated and, whenever the user releases the mouse button, the item being replaced gets a new definitive place in the grid.

See also:: elm_gengrid_reorder_mode_get()

Parameters:

[in]	obj	The elm gengrid object
[in]	reorder_mode	Use `EINA_TRUE` to turn reordering on, `EINA_FALSE` to turn it off

Elm_Object_Select_Mode elm_gengrid_select_mode_get ( const Elm_Gengrid * obj )

Get the gengrid select mode.

Since :: 2.3

Returns:: The select mode (If getting mode fails, it returns ELM_OBJECT_SELECT_MODE_MAX)

See also:: elm_gengrid_select_mode_set()

Parameters:

[in] obj The elm gengrid object

void elm_gengrid_select_mode_set	(	Elm_Gengrid *	obj,
		Elm_Object_Select_Mode	mode
	)

Set the gengrid select mode.

Since :: 2.3

Remarks:

elm_gengrid_select_mode_set() changes item select mode in the gengrid widget.

ELM_OBJECT_SELECT_MODE_DEFAULT : Items will only call their selection func and callback when first becoming selected. Any further clicks will do nothing, unless you set always select mode.
ELM_OBJECT_SELECT_MODE_ALWAYS : This means that, even if selected, every click will make the selected callbacks be called.
ELM_OBJECT_SELECT_MODE_NONE : This will turn off the ability to select items entirely and they will neither appear selected nor call selected callback functions.

See also:: elm_gengrid_select_mode_get()

Parameters:

[in]	obj	The elm gengrid object
[in]	mode	The select mode

Elm_Object_Item* elm_gengrid_selected_item_get ( const Elm_Gengrid * obj )

Get the selected item in a given gengrid widget.

Since :: 2.3

Returns:: The selected item's handle or NULL, if none is selected at the moment (and on errors)

Remarks:: This returns the selected item in obj. If multi selection is enabled on obj (

See also:: elm_gengrid_multi_select_set()), only the first item in the list is selected, which might not be very useful. For that case, see elm_gengrid_selected_items_get().

Parameters:

[in] obj The elm gengrid object

const Eina_List* elm_gengrid_selected_items_get ( const Elm_Gengrid * obj )

Get a list of selected items in a given gengrid.

Since :: 2.3

Returns:: The list of selected items or NULL, if none is selected at the moment (and on errors)

Remarks:: This returns a list of the selected items, in the order that they appear in the grid. This list is only valid as long as no more items are selected or unselected (or unselected implicitly by deletion). The list contains Gengrid item pointers as data, naturally.
