Jean,
If you know in advance (i.e. before you draw it) you're not going to use
the widget can you just set map=0 to the base of the widget when you
create it?
This should (untested!) still allow your timer events and various
widget_controls to work without having to re-factor any code but will
stop it appearing on the screen.
Thanks,
Allan
