/**
 | 
						|
    Base class for persistent windows.
 | 
						|
 | 
						|
    Compared to wxPersistentObject this class does three things:
 | 
						|
        - Most importantly, wxPersistentWindow catches wxWindowDestroyEvent
 | 
						|
        generated when the window is destroyed and saves its properties
 | 
						|
        automatically when it happens.
 | 
						|
        - It implements GetName() using wxWindow::GetName() so that the derived
 | 
						|
        classes don't need to do it.
 | 
						|
        - It adds a convenient wxPersistentWindow::Get() accessor returning the
 | 
						|
        window object of the correct type.
 | 
						|

        The constructor uses wxEvtHandler::Connect() to catch
 | 
						|
        wxWindowDestroyEvent generated when the window is destroyed and call
 | 
						|
        wxPersistenceManager::SaveAndUnregister() when this happens. This
 | 
						|
        ensures that the window properties are saved and that this object

        itself is deleted when the window is.

        before saving or restoring persistent properties.
