The function simple-pane-handle
returns the handle of pane in the system that displays it, if there is an underlying window.
On Microsoft Windows handle is the hwnd of pane.
On X11/Motif, handle is the windowid of the main part of pane (type Window in the X library).
If pane is not displayed, or if pane does not have an underlying window, then handle is nil
. Note that layouts do not always have an underlying window.
Use this function with caution: in general, drawing and moving of CAPI windows should be done through the CAPI.
