PtFindDisjoint()
Return the nearest disjoint parent widget
Synopsis:
PtWidget_t *PtFindDisjoint( PtWidget_t *widget );
Library:
ph
Description:
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:
- PtWindow
- PtMenu
- PtRegion
Examples of widgets that aren't disjoint include:
- PtButton
- PtBkgd
- PtRect
Returns:
A widget pointer to the nearest disjoint parent of widget, or NULL if no disjoint container parent was found.
