A Layout is a direct realization of elm-layout-class.

This is a container widget that takes a standard Edje design file and wraps it very thinly in a widget.

An Edje design (theme) file has a very wide range of possibilities to describe the behavior of elements forming a layout. Check out the Edje documentation and the EDC reference to get more information about what can be done with Edje.

Just like List, Box, and other container widgets, any object added to the Layout will become its child, meaning that it will be deleted if the Layout is deleted, moved if the Layout is moved, and so on.

The layout widget may contain as many parts/children as described in its theme file. Some of these children can have special types, such as content holder ones (swallow spots), boxes or tables. These are parts meant to contain others. For instance, objects can be added to different table parts by specifying the respective table part names. The same is valid for swallows and boxes.

The objects added as children of a layout will behave as described in the part description where they were added. There are 3 possible types of parts where a child can be added:

Content (@c SWALLOW part)

Only one object can be added to the SWALLOW part at a time (but you still can have many SWALLOW parts and one object on each of them). Use the elm_layout_content_set()/get/unset functions to set, retrieve and unset objects as content of the SWALLOW. After being set to this part, the object's size, position, visibility, clipping and other description properties will be totally controlled by the description of the given part (inside the Edje theme file).

One can use evas_object_size_hint_* functions on the child to have some kind of control over its behavior, but the resulting behavior will still depend heavily on the SWALLOW part's description.

The Edje theme also can change the part description, based on signals or scripts running inside the theme. This change can also be animated. All of this will affect the child object set as content accordingly. The object's size will be changed if the part size is changed, it will animate moving accordingly if the part is moving, and so on.

The following picture demonstrates a layout widget with a child object added to its SWALLOW:

Box (@c BOX part)

An Edje BOX part is very similar to the Elementary Box widget. It allows one to add objects to the box and have them distributed along its area, accordingly to the specified layout property (now by layout we mean the chosen layouting design of the Box, not the layout widget itself).

A similar effect for having a box with its position, size and other things controlled by the layout theme would be to create an Elementary Box widget and add it as content in a SWALLOW part.

The main difference to that, by using the layout box instead, is that its behavior, like layouting format, padding, align, etc., will all be controlled by the theme. This means, for example, that a signal could be sent to the layout's theme (with elm_layout_signal_emit()) and the signal be handled by changing the box's padding, or alignment, or both. Using the Elementary Box widget is not necessarily harder or easier, it just depends on the circumstances and requirements.

The layout box can be used through the elm_layout_box_* set of functions.

The following picture demonstrates a Layout widget with many child objects added to its BOX part:

Table (@c TABLE part)

Just like the Box (BOX part), the layout table is very similar to the Elementary Table widget. It allows one to add objects to the table by specifying the row and column where the object should be added, and any column or row span, if necessary.

Again, we could have this design by adding a table widget to a SWALLOW part, using elm_layout_content_set(). The same difference happens here when choosing to use the layout table (a TABLE part) instead of the table in a SWALLOW part. It's just a matter of convenience.

The layout table can be used through the elm_layout_table_* set of functions.

The following picture demonstrates a layout widget with many child objects added to its TABLE part:

Predefined Layouts

Another interesting thing about the layout widget is that it offers some predefined themes that come with the default Elementary theme. These themes can be set by the call elm_layout_theme_set(), and provide some basic functionality depending on the theme used.

Most of them already send some signals, some already provide a toolbar or back and next buttons.

These are the available predefined theme layouts. All of them have class = layout, group = application, and style = one of the following options:

toolbar-content - for applications with a toolbar and main content area
toolbar-content-back - for applications with a toolbar and main content (with a back button) and title areas
toolbar-content-back-next - for applications with a toolbar and main content (with back and next buttons) and title areas
content-back - for application with main content (with a back button) and title areas
content-back-next - for applications with main content (with back and next buttons) and title areas
toolbar-vbox - for applications with a toolbar and main content area as a vertical box
toolbar-table - for applications with a toolbar and main content area as a table

Emitted signals

This widget emits the following signals:

"theme,changed" - The theme was changed.
"language,changed" - the program's language changed

Since :: 2.3

Parameters:

[in]	obj	The object.
[in]	part	The box part to which the object will be prepended.
[in]	child	The child object to prepend to box.

Evas_Object* elm_layout_box_remove	(	Elm_Layout *	obj,
		const char *	part,
		Evas_Object *	child
	)

Remove a child of the given part box.

The object will be removed from the box part and its lifetime will not be handled by the layout anymore. This is equivalent to elm_layout_content_unset for box.

Since :: 2.3

Parameters:

[in]	obj	The object.
[in]	part	The box part name to remove child.
[in]	child	The object to remove from box.

Returns:: The object that was being used, or null if not found.

Eina_Bool elm_layout_box_remove_all	(	Elm_Layout *	obj,
		const char *	part,
		Eina_Bool	clear
	)

Remove all children of the given part box.

The objects will be removed from the box part and their lifetime will not be handled by the layout anymore. This is equivalent to elm_layout_box_remove for all box children.

Since :: 2.3

Parameters:

[in]	obj	The object.
[in]	part	The box part name to remove child.
[in]	clear	If true, then all objects will be deleted as well, otherwise they will just be removed and will be dangling on the canvas.

Evas_Object* elm_layout_content_get	(	const Evas_Object *	obj,

	)

Set the layout content.

Parameters:

obj	The layout object
swallow	The swallow part name in the edje file
content	The child that will be added in this layout object

Returns:: EINA_TRUE on success, EINA_FALSE otherwise

Once the content object is set, a previously set one will be deleted. If you want to keep that old content object, use the elm_layout_content_unset() function.

Note:: In an Edje theme, the part used as a content container is called SWALLOW. This is why the parameter name is called swallow, but it is expected to be a part name just like the second parameter of elm_layout_box_append().

See also:: elm_layout_box_append(); elm_layout_content_get(); elm_layout_content_unset(); Box (BOX part)

Since :: 2.3

Eina_List* elm_layout_content_swallow_list_get ( const Evas_Object * obj )

void elm_layout_signal_emit	(	Elm_Layout *	obj,
		const char *	emission,
		const char *	source
	)

Send a (Edje) signal to a given layout widget's underlying Edje object.

This function sends a signal to the underlying Edje object of obj. An Edje program on that Edje object's definition can respond to a signal by specifying matching 'signal' and 'source' fields.

Since :: 2.3

Parameters:

[in]	obj	The object.
[in]	emission	The signal's name string.
[in]	source	The signal's source string.

void elm_layout_sizing_eval ( Elm_Layout * obj )

Eval sizing.

Manually forces a sizing re-evaluation. This is useful when the minimum size required by the edje theme of this layout has changed. The change on the minimum size required by the edje theme is not immediately reported to the elementary layout, so one needs to call this function in order to tell the widget (layout) that it needs to reevaluate its own size.

The minimum size of the theme is calculated based on minimum size of parts, the size of elements inside containers like box and table, etc. All of this can change due to state changes, and that's when this function should be called.

Also note that a standard signal of "size,eval" "elm" emitted from the edje object will cause this to happen too.

Since :: 2.3

Parameters:

[in] obj The object.

void elm_layout_sizing_restricted_eval	(	Elm_Layout *	obj,
		Eina_Bool	width,
		Eina_Bool	height
	)

Request sizing reevaluation, restricted to current width and/or height.

Useful mostly when there are TEXTBLOCK parts defining the height of the object and nothing else restricting it to a minimum width. Calling this function will restrict the minimum size in the Edje calculation to whatever size it the layout has at the moment.

Since :: 3.0

Parameters:

[in]	obj	The object.
[in]	width	Restrict minimum size to the current width.
[in]	height	Restrict minimum size ot the current height.

Since (EFL) :: 1.8

Eina_Bool elm_layout_table_clear	(	Elm_Layout *	obj,
		const char *	part,
		Eina_Bool	clear
	)

Remove all the child objects of the given part table.

The objects will be removed from the table part and their lifetime will not be handled by the layout anymore. This is equivalent to elm_layout_table_unpack for all table children.

Since :: 2.3

Parameters:

[in]	obj	The object.
[in]	part	The table part name to remove child.
[in]	clear	If true, then all objects will be deleted as well, otherwise they will just be removed and will be dangling on the canvas.

Eina_Bool elm_layout_table_pack	(	Elm_Layout *	obj,
		const char *	part,
		Evas_Object *	child,
		unsigned short	col,
		unsigned short	row,
		unsigned short	colspan,
		unsigned short	rowspan
	)

Insert child to layout table part.

Once the object is inserted, it will become child of the table. Its lifetime will be bound to the layout, and whenever the layout dies the child will be deleted automatically. One should use elm_layout_table_unpack to make this layout forget about the object.

If colspan or rowspan are bigger than 1, that object will occupy more space than a single cell.

Since :: 2.3

Parameters:

[in]	obj	The object.
[in]	part	The box part to pack child.
[in]	child	The child object to pack into table.
[in]	col	The column to which the child should be added. (>= 0)
[in]	row	The row to which the child should be added. (>= 0)
[in]	colspan	How many columns should be used to store this object. (>= 1)
[in]	rowspan	How many rows should be used to store this object. (>= 1)

Evas_Object* elm_layout_table_unpack	(	Elm_Layout *	obj,
		const char *	part,
		Evas_Object *	child
	)

Unpack (remove) a child of the given part table.

The object will be unpacked from the table part and its lifetime will not be handled by the layout anymore. This is equivalent to elm_layout_content_unset for table.

Since :: 2.3

Parameters:

[in]	obj	The object.
[in]	part	The table part name to remove child.
[in]	child	The object to remove from table.

Returns:: The object that was being used, or null if not found.

const char* elm_layout_text_get	(	const Elm_Layout *	obj,
		const char *	part
	)

Get the text set in the given part.

Since :: 2.3

Parameters:

[in]	obj	The object.
[in]	part	The TEXT part to retrieve the text off.

Eina_Bool elm_layout_text_set	(	Elm_Layout *	obj,
		const char *	part,
		const char *	text
	)

Set the text of the given part.

Since :: 2.3

Parameters:

[in]	obj	The object.
[in]	part	The TEXT part where to set the text.
[in]	text	The text to set.

int elm_layout_thaw ( Elm_Layout * obj )

Thaws the Elementary object.

This function thaws the given Edje object and the Elementary sizing calc.

Note:: If sucessives freezes were done, an equal number of thaws will be required.

Eina_Bool elm_layout_theme_set	(	Elm_Layout *	obj,
		const char *	klass,
		const char *	group,
		const char *	style
	)
