Clipped smart object is a base to construct other smart objects based on the concept of having an internal clipper that is applied to all children objects.
This clipper will control the visibility, clipping and color of sibling objects (remember that the clipping is recursive, and clipper color modulates the color of its clippees). By default, this base will also move children relative to the parent, and delete them when parent is deleted. In other words, it is the base for simple object grouping.
See some examples of this group of functions.
|void evas_object_smart_clipped_smart_set||(||Evas_Smart_Class *||sc||)|
Set a given smart class' callbacks so it implements the clipped smart object"'s interface.
|sc||The smart class handle to operate on|
This call will assign all the required methods of the
sc Evas_Smart_Class instance to the implementations set for clipped smart objects. If one wants to "subclass" it, call this function and then override desired values. If one wants to call any original method, save it somewhere. Example:
Default behavior for each of Evas_Smart_Class functions on a clipped smart object are:
add:creates a hidden clipper with "infinite" size, to clip any incoming members;
del:delete all children objects;
move:move all objects relative relatively;
show:if there are children objects, show clipper;
color_set:set the color of clipper;
clip_set:set clipper of clipper;
clip_unset:unset the clipper of clipper;
