Is there some way to use XtAddEventHandler() or XtAddRawEventHandler() with gadgets? I tried installing a ButtonPressMask event handler in a XmCreatePushButtonGadget, and was surprised at the results. It wouldn't even handle exposure events after that! Does someone know a trick I can use to emulate event handling (or translations) for a gadget? Or am I asking too much? I know that the behavior is being managed somewhere; is there some way to modify this behavior? Any tips will be appreciated. -- Roger Meunier @ Zuken, Inc. Yokohama, Japan (roger@zuken.co.jp)

So, for example, if you wanted to do something when the pointer entered the gadget, you'd do event handling in the parent and check for the pointer being in the gadgets extent.

That's basically the lead that I need. Thanx! Now, one more quick question: is there some way to alter the behavior of the XmManager widget which has the Gadget as a child, e.g., through resources? -- Roger Meunier @ Zuken, Inc.
