ModalWindow is used to present a window that grabs input focus when activated. Its "end" method is used to terminate the grab and remove the window from view. Code shamelessly stolen from SimpleDialog.

__init__ (
        self,
        master=None,
        resizable=Tkinter.FALSE,
        *args,
        *kw,
        )

end ( self,  value=None )

run ( self,  master=None )
