Usually you have turn your thinking around when you design widget
programs. In this case, you will probably have to create a button
widget before you begin your processing, and then periodically poll
that widget for any activity. If you retrieve your own events
directly (instead of using XMANAGER) you can do this.
As David points out, it is currently impossible to directly control an
IDL computing process with just a widget. After all, how can an IDL
program control itself?

It's not going to happen. At least not the way
you were hoping it would. Tell us more about
what you are trying to do.
Cheers,
