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, resized, etc as a single image. So it will improve performance when you have a complex interface, with a lot of elements, and will need to resize or 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 Evas_Object * | obj | ) |
Get a value whether alpha blending is enabled or not.
- Parameters:
-
obj The mapbuf object.
- Returns:
EINA_TRUE
means alpha blending is enabled.EINA_FALSE
indicates it's disabled. Ifobj
isNULL
,EINA_FALSE
is returned.
- See also:
- elm_mapbuf_alpha_set() for details.
void elm_mapbuf_alpha_set | ( | Evas_Object * | obj, |
Eina_Bool | alpha | ||
) |
Set or unset alpha flag for map rendering.
- Parameters:
-
obj The mapbuf object. alpha EINA_TRUE
to enable alpha blending orEINA_FALSE
to disable it.
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.
Eina_Bool elm_mapbuf_enabled_get | ( | const Evas_Object * | obj | ) |
Get a value whether map is enabled or not.
- Parameters:
-
obj The mapbuf object.
- Returns:
EINA_TRUE
means map is enabled.EINA_FALSE
indicates it's disabled. Ifobj
isNULL
,EINA_FALSE
is returned.
- See also:
- elm_mapbuf_enabled_set() for details.
void elm_mapbuf_enabled_set | ( | Evas_Object * | obj, |
Eina_Bool | enabled | ||
) |
Enable or disable the map.
- Parameters:
-
obj The mapbuf object. enabled EINA_TRUE
to enable map orEINA_FALSE
to disable it.
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.
Eina_Bool elm_mapbuf_smooth_get | ( | const Evas_Object * | obj | ) |
Get a value whether smooth map rendering is enabled or not.
- Parameters:
-
obj The mapbuf object.
- Returns:
EINA_TRUE
means smooth map rendering is enabled.EINA_FALSE
indicates it's disabled. Ifobj
isNULL
,EINA_FALSE
is returned.
- See also:
- elm_mapbuf_smooth_set() for details.
void elm_mapbuf_smooth_set | ( | Evas_Object * | obj, |
Eina_Bool | smooth | ||
) |
Enable or disable smooth map rendering.
- Parameters:
-
obj The mapbuf object. smooth EINA_TRUE
to enable smooth map rendering orEINA_FALSE
to disable it.
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.
