Use the "Widget_Control" command to do this. Assume you have a button
called data_button somewhere in your widget hierarchy declared like
this:
data_button = Widget_Button(base, Value='Data', UValue='data_button')
Just prior to realizing the widget hierarchy you can call the following
command to gray it out:
Widget_Control, data_button, Sensitive=0
During event processing you can call Widget_Control again and set the
"Sensitive" value to 1 to make the button available.
Widget_Control, data_button, Sensitive=1

Michael,
You seem to be referring to the sensitivity of a widget.
Use:
WIDGET_CONTROL, widget_id, SENSITIVE=0
This makes the widget insensitive to the user and under MOTIF
or WINDOWS and changes the appearance of the widget.
The widget can be resensitized by:
WIDGET_CONTROL, widget_id, /SENSITIVE
Yours truly,
Ken Knighton

In PV-Wave you get the widget ID of the menu item and use it in a WwSet
to gray it out.
Example:
menuid = WwMenuBar(parent,items,Menus=menus)
itemids = WtGet(menus(i),/Child) ; i=menu from menubar
status = WtSet(itemids(j),/Nonsensitive) ; j=the index of item from
menu i
Hope this helps,
