protected void OnCanvasHierarchyChanged();

Description

Called when the state of the parent Canvas is changed.

When a parent canvas is either enabled, disabled or a nested canvas's OverrideSorting is changed this function is called. You can for example use this to modify objects below a canvas that may depend on a parent canvas - for example, if a canvas is disabled you may want to halt some processing of a UI element.
