Return the nearest disjoint parent widget
PtWidget_t *PtFindDisjoint( PtWidget_t *widget );
ph
This function returns the nearest disjoint parent widget (which could be
widget itself). A disjoint widget owns regions that aren't
children of its parent's regions. Any clipping set by the parent of a disjoint
widget isn't applied to the disjoint widget. The regions of disjoint
widgets are sensitive and opaque to expose events.
A disjoint widget's class_rec has the Pt_DISJOINT
flag set.
Examples of widgets that are disjoint include:
Examples of widgets that aren't disjoint include:
A widget pointer to the nearest disjoint parent of widget,
or NULL if no disjoint container parent was found.
