A group object is a container for other canvas objects. Its children move along their parent and are often clipped with a common clipper. This is part of the legacy smart object concept.
A group is not necessarily a container (see Efl.Container) in the sense that a standard widget may not have any empty slots for content. However it's still a group of low-level canvas objects (clipper, raw objects, etc.).
Clip one object to another.
Efl_Canvas_Object *efl_canvas_object_clipper_get(const Eo *obj); void efl_canvas_object_clipper_set(Eo *obj, Efl_Canvas_Object *clipper);
The general/main color of the given Evas object.
void efl_gfx_color_get(const Eo *obj, int *r, int *g, int *b, int *a); void efl_gfx_color_set(Eo *obj, int r, int g, int b, int a);
Implement this method to provide optional initialization code for your object.
Efl_Object *efl_constructor(Eo *obj);
Build a read-only name for this object used for debugging.
void efl_debug_name_override(Eo *obj, Eina_Strbuf *sb);
Implement this method to provide deinitialization code for your object if you need it.
void efl_destructor(Eo *obj);
Triggers an immediate recalculation of this object's geometry.
void efl_canvas_group_calculate(Eo *obj);
Marks the object as dirty.
void efl_canvas_group_change(Eo *obj);
Set a canvas object as a member of a given group (or smart object).
void efl_canvas_group_member_add(Eo *obj, Efl_Canvas_Object *sub_obj);
Finds out if a given object is a member of this group.
Eina_Bool efl_canvas_group_member_is(const Eo *obj, const Efl_Canvas_Object *sub_obj);
Removes a member object from a given smart object.
void efl_canvas_group_member_remove(Eo *obj, Efl_Canvas_Object *sub_obj);
Returns an iterator over the children of this object, which are canvas objects.
Eina_Iterator *efl_canvas_group_members_iterate(const Eo *obj);
group_need_recalculate (get, set)
Indicates that the group's layout needs to be recalculated.
Eina_Bool efl_canvas_group_need_recalculate_get(const Eo *obj); void efl_canvas_group_need_recalculate_set(Eo *obj, Eina_Bool value);
Disables all rendering on the canvas.
Eina_Bool efl_canvas_object_no_render_get(const Eo *obj); void efl_canvas_object_no_render_set(Eo *obj, Eina_Bool enable);
This handles text paragraph direction of the given object. Even if the given object is not textblock or text, its smart child objects can inherit the paragraph direction from the given object. The default paragraph direction is
Efl_Text_Bidirectional_Type efl_canvas_object_paragraph_direction_get(const Eo *obj); void efl_canvas_object_paragraph_direction_set(Eo *obj, Efl_Text_Bidirectional_Type dir);
The 2D position of a canvas object.
Eina_Position2D efl_gfx_entity_position_get(const Eo *obj); void efl_gfx_entity_position_set(Eo *obj, Eina_Position2D pos);
The visibility of a canvas object.
Eina_Bool efl_gfx_entity_visible_get(const Eo *obj); void efl_gfx_entity_visible_set(Eo *obj, Eina_Bool v);
const Efl_Canvas_Object *efl_canvas_group_clipper_get(const Eo *obj);
