/**
    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.

        Constructor for a persistent window object.

        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.

        Notice that window names are usually not unique while this function
        must return a unique (at least among the objects of this type) string.
        Because of this you need to specify a non-default window name in its
        constructor when creating it or explicitly call wxWindow::SetName()
        before saving or restoring persistent properties.
