Superclass for all compound widgets
For more information, see the diagram of the widget hierarchy.
None - not normally instantiated.
The PtCompound superclass provides the ability to combine widgets into a compound. A compound widget can export its subordinate children to let you get and set their resources, or it can block access to them to provide a "canned" appearance.
If the widget modifies an inherited resource, the "Default override" column indicates the new value. This modification affects any subclasses of the widget.
