Detailed Description

This holds one content object and uses an Evas Map of transformation points to be later used with this content. So the content will be moved as a single image. So it will improve performance when you have a complex interface, with a lot of elements, and will need to move it frequently (the content object and its children).

This widget inherits from The Elementary Container Class, so that the functions meant to act on it will work for mapbuf objects:

Default content parts of the mapbuf widget that you can use are:

"default" - The main content of the mapbuf

To enable map, elm_mapbuf_enabled_set() should be used.

See how to use this widget in this example: Mapbuf Widget Example

Function Documentation

Evas_Object* elm_mapbuf_add ( Evas_Object * parent )

Add a new mapbuf widget to the given parent Elementary (container) object.

Parameters

parent The parent object.

Returns: A new mapbuf widget handle or NULL, on errors.

This function inserts a new mapbuf widget on the canvas.

Eina_Bool elm_mapbuf_alpha_get ( const Elm_Mapbuf * obj )

Get a value whether alpha blending is enabled or not.

Returns: The alpha state.

References elm_obj_mapbuf_alpha_get().

void elm_mapbuf_alpha_set	(	Elm_Mapbuf *	obj,
		Eina_Bool	alpha
	)

Set or unset alpha flag for map rendering.

This sets alpha flag for map rendering. If the object is a type that has its own alpha settings, then this will take precedence. Only image objects have this currently. It stops alpha blending of the map area, and is useful if you know the object and/or all sub-objects is 100% solid.

Alpha is enabled by default.

Parameters

[in] alpha The alpha state.

References elm_obj_mapbuf_alpha_set().

Eina_Bool elm_mapbuf_auto_get ( const Elm_Mapbuf * obj )

Get a value whether auto mode is enabled or not.

Returns: The auto mode state.

References elm_obj_mapbuf_auto_get().

void elm_mapbuf_auto_set	(	Elm_Mapbuf *	obj,
		Eina_Bool	on
	)

Set or unset auto flag for map rendering.

When a ampbuf object has "auto mode" enabled, then it will enable and disable map mode based on current visibility. Mapbuf will track if you show or hide it AND if the object is inside the canvas viewport or not when it is moved or resized. Note that if you turn automode off, then map mode will be in a disabled state at this point. When you turn it on for the first time, the current state will be evaluated base on current properties of the mapbuf object.

Auto mode is disabled by default.

Parameters

[in] on The auto mode state.

References elm_obj_mapbuf_auto_set().

Eina_Bool elm_mapbuf_enabled_get ( const Elm_Mapbuf * obj )

Get a value whether map is enabled or not.

Returns: The enabled state.

References elm_obj_mapbuf_enabled_get().

void elm_mapbuf_enabled_set	(	Elm_Mapbuf *	obj,
		Eina_Bool	enabled
	)

Enable or disable the map.

This enables the map that is set or disables it. On enable, the object geometry will be saved, and the new geometry will change (position and size) to reflect the map geometry set.

Also, when enabled, alpha and smooth states will be used, so if the content isn't solid, alpha should be enabled, for example, otherwise a black rectangle will fill the content.

When disabled, the stored map will be freed and geometry prior to enabling the map will be restored.

It's disabled by default.

Parameters

[in] enabled The enabled state.

References elm_obj_mapbuf_enabled_set().

void elm_mapbuf_point_color_get	(	Elm_Mapbuf *	obj,
		int	idx,
		int *	r,
		int *	g,
		int *	b,
		int *	a
	)

Get the color set on a vertex in the mapbuf.

This gets the color set by elm_mapbuf_point_color_set on the given vertex of the mapbuf.

Parameters

[out]	r	Pointer to red return.
[out]	g	Pointer to green return.
[out]	b	Pointer to blue return.
[out]	a	Pointer to alpha return.

void elm_mapbuf_point_color_set	(	Elm_Mapbuf *	obj,
		int	idx,
		int	r,
		int	g,
		int	b,
		int	a
	)

Set the color of a vertex in the mapbuf.

This sets the color of the vertex in the mapbuf. Colors will be linearly interpolated between vertex points through the mapbuf. Color will multiply the "texture" pixels (like GL_MODULATE in OpenGL). The default color of a vertex in a mapbuf is white solid (255, 255, 255, 255) which means it will have no affect on modifying the texture pixels.

Parameters

[in]	r	Red (0 - 255)
[in]	g	Green (0 - 255)
[in]	b	Blue (0 - 255)
[in]	a	Alpha (0 - 255)

Eina_Bool elm_mapbuf_smooth_get ( const Elm_Mapbuf * obj )

Get a value whether smooth map rendering is enabled or not.

Returns: The smooth mode state.

References elm_obj_mapbuf_smooth_get().

void elm_mapbuf_smooth_set	(	Elm_Mapbuf *	obj,
		Eina_Bool	smooth
	)

Enable or disable smooth map rendering.

This sets smoothing for map rendering. If the object is a type that has its own smoothing settings, then both the smooth settings for this object and the map must be turned off.

By default smooth maps are enabled.

Parameters

[in] smooth The smooth mode state.
