161) How do I simulate a button press/release event for a widget?


You can do this using XSendEvent(); it's likely that you're not setting the
window field in the event, which Xt needs in order to match to the widget
which should receive the event.

If you're sending events to your own application, then you can use
XtDispatchEvent() instead. This is more efficient than XSendEvent() in that
you avoid a round-trip to the server.

Depending on how well the widget was written, you may be able to call its
action procedures in order to get the effects you want.
