why don't you use an own widget_base for the widget_button and then
hide/unhide this base?

No. I would hide the button completely but I think is not possible.
The SENSITIVE option is not bad...
Thanks for your suggestion..

Is this what you mean?
WIDGET_CONTROL, ButtonID, SENSITIVE = 0

If you want it *completely* hidden while insensitive, create an 8-bit
bitmap image as your button icon (this may only work on Windows).

I don't know. I doubt it is possible in a platform-independent
way. I think the best you can reasonably hope for is to make
your button insensitive (SENSITIVE=0).

Great idea, Justus, works a treat!

From the helpfiles:
While it is possible to call WIDGET_CONTROL, MAP=0 with the widget ID
of any widget, only base widgets can actually be unmapped. If you
specify a widget ID that is not from a base widget, IDL searches
upward in the widget hierarchy until it finds the closest base widget.
The map operation is applied to that base.

So you can actually hide the button itself, and so long as it has its
own associated child base that it doesn't share with anything else, by
using
WIDGET_CONTROL, Button_ID, MAP = 0

Works for me. Thanks for this great tip!
Chris
