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 elm-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.

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.
- Since :
- 2.3
Eina_Bool elm_mapbuf_alpha_get | ( | const Elm_Mapbuf * | obj | ) |
Get a value whether alpha blending is enabled or not.
- Since :
- 2.3
- Parameters:
-
[in] obj The object.
- Returns:
- The alpha state.
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.
- Since :
- 2.3
- Parameters:
-
[in] obj The object. [in] alpha The alpha state.
Eina_Bool elm_mapbuf_auto_get | ( | const Elm_Mapbuf * | obj | ) |
Get a value whether auto mode is enabled or not.
- Since :
- 3.0
- Parameters:
-
[in] obj The object.
- Returns:
- The auto mode state.
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.
- Since :
- 3.0
- Parameters:
-
[in] obj The object. [in] on The auto mode state.
Eina_Bool elm_mapbuf_enabled_get | ( | const Elm_Mapbuf * | obj | ) |
Get a value whether map is enabled or not.
- Since :
- 2.3
- Parameters:
-
[in] obj The object.
- Returns:
- The enabled state.
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.
- Since :
- 2.3
- Parameters:
-
[in] obj The object. [in] enabled The enabled state.
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.
- Since :
- 2.3
- Parameters:
-
[in] obj The object. [in] idx Index of point get. Must be smaller than map size. [out] r Pointer to red return. [out] g Pointer to green return. [out] b Pointer to blue return. [out] a Pointer to alpha return.
- Since (EFL) :
- 1.9
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.
- Since :
- 2.3
- Parameters:
-
[in] obj The object. [in] idx Index of point to change. Must be smaller than mapbuf size. [in] r Red (0 - 255) [in] g Green (0 - 255) [in] b Blue (0 - 255) [in] a Alpha (0 - 255)
- Since (EFL) :
- 1.9
Eina_Bool elm_mapbuf_smooth_get | ( | const Elm_Mapbuf * | obj | ) |
Get a value whether smooth map rendering is enabled or not.
- Since :
- 2.3
- Parameters:
-
[in] obj The object.
- Returns:
- The smooth mode state.
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.
- Since :
- 2.3
- Parameters:
-
[in] obj The object. [in] smooth The smooth mode state.
