Humm. I think that should work. Try setting SCR_XSIZE
and SCR_YSIZE to a single pixel. Maybe no one will
notice it. :-)

Just be sure you run this program on Windows. Otherwise,
all hell breaks loose. :-)

No, probably not in the way you are thinking about it.
Why don't you just disable it if you don't want the user
to use it:
Widget_Control, slider, SENSTIVE=0
