has_overlaps

Asks the actor's implementation whether it may contain overlapping primitives.

For example; Clutter may use this to determine whether the painting should be redirected to an offscreen buffer to correctly implement the opacity property.

Custom actors can override the default response by implementing the has_overlaps virtual function. See set_offscreen_redirect for more information.

Parameters:

this

A Actor

Returns:

true if the actor may have overlapping primitives, and false otherwise
