Sorry I forgot to specify - I want the routine to work for
a WIDGET_DRAW, i.e. the BOX_CURSOR routine does not apply here!

You can get box_cursor to work in a draw widget by having a menu
entry or button labeled 'box' that executes something like this:
wset, window_number
box_cursor, x0, y0, nx, ny
wset, original_window
You get the window number using widget_control:
widget_control, id_of_draw_widget, get_value=window_number
I'd like to hear about other methods too. - Roger
