        Close(self, bool force=False) -> bool



        This function simply generates a EVT_CLOSE event whose handler usually

        tries to close the window. It doesn't close the window itself,

        however.  If force is False (the default) then the window's close

        handler will be allowed to veto the destruction of the window.

    　　self.Destroy()

    　　"""

        Destroy(self) -> bool



        Destroys the window safely.  Frames and dialogs are not destroyed

        immediately when this function is called -- they are added to a list

        of windows to be deleted on idle time, when all the window's events

        have been processed. This prevents problems with events being sent to

        non-existent windows.



        Returns True if the window has either been successfully deleted, or it

        has been added to the list of windows pending real deletion.
