Detailed Description

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 The Elementary 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.swallow.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.
• "released" - The user released the an item. The event_info parameter is the item that was released.
• "clicked,double" - The user has double-clicked an item. The event_info parameter is the gengrid item that was double-clicked.

void

)

Add a new gengrid item class in a given gengrid widget.

Returns

New allocated a gengrid item class.

This adds gengrid item class for the gengrid widget. When adding an item, gengrid_item_{append, prepend, insert} function needs item class of the item. Given callback parameters are used at retrieving {text, content} of added item. Set as NULL if it's not used. If there's no available memory, return can be NULL.

elm_gengrid_item_tooltip_text_set()

void elm_gengrid_item_tooltip_text_set	(	Elm_Object_Item *	it,
		const char *	text
	)

Set the text to be shown in a given gengrid item's tooltips.

Parameters

it	The gengrid item
text	The text to set in the content

This call will setup the text to be used as tooltip to that item (analogous to elm_object_tooltip_text_set(), but being item tooltips with higher precedence than object tooltips). 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().

elm_gengrid_item_tooltip_style_set()

void elm_gengrid_item_tooltip_style_set	(	Elm_Object_Item *	it,
		const char *	style
	)

Set a different style for a given gengrid item's tooltip.

Parameters

it	gengrid item with tooltip set
style	the theme style to use on tooltips (e.g. "default", "transparent", etc)

Tooltips can have alternate styles to be displayed on, which are defined by the theme set on Elementary. 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".

Note

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()

elm_gengrid_item_tooltip_style_get()

elm_gengrid_item_tooltip_style_get()

const char * elm_gengrid_item_tooltip_style_get

(

const Elm_Object_Item *

it

)

Get the style set a given gengrid item's tooltip.

Parameters

it	gengrid item with tooltip already set on.

Returns

style the theme style in use, which defaults to "default". If the object does not have a tooltip set, then NULL is returned.

	)

Set a different style for a given custom cursor set for a gengrid item.

Parameters

it	gengrid item with custom cursor set
style	the theme style to use (e.g. "default", "transparent", etc)

This function only makes sense when one is using custom mouse cursor decorations defined in a theme file , which can have, given a cursor name/type, alternate styles on it. It works analogously as elm_object_cursor_style_set(), but here applied only to gengrid item objects.

Warning

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

Parameters

it	item with custom (custom) cursor already set on
engine_only	Use EINA_TRUE to have cursors looked for only on those provided by the rendering engine, EINA_FALSE to have them searched on the widget's theme, as well.

Note

This call is of use only if you've set a custom cursor for gengrid items, with elm_gengrid_item_cursor_set().

By default, cursors will only be looked for between those provided by the rendering engine.

elm_gengrid_item_cursor_engine_only_get()

Eina_Bool elm_gengrid_item_cursor_engine_only_get

(

const Elm_Object_Item *

	)

Set the gengrid item's select mode.

Parameters

it	The gengrid item object
mode	The select mode

elm_gengrid_select_mode_set() changes item's select mode.

• ELM_OBJECT_SELECT_MODE_DEFAULT : The item 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 the item entirely and they will neither appear selected nor call selected callback functions.
• ELM_OBJECT_SELECT_MODE_DISPLAY_ONLY : This will apply no-finger-size rule with ELM_OBJECT_SELECT_MODE_NONE. No-finger-size rule makes an item can be smaller than lower limit. Clickable objects should be bigger than human touch point device (your finger) for some touch or small screen devices. So it is enabled, the item can be shrink than predefined finger-size value. And the item will be updated.

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

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.
