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
