AbstractHandler¶Base class for persistent windows, uses the window name as persistent name by default and automatically reacts to the window destruction.
Note
This is an abstract class. If you wish to add another (custom) handler for your widgets, you should derive from AbstractHandler and override the Save, Restore and GetKind methods.
Known Subclasses¶
