Could someone explain why/how UIL allows you to put a create callback on any widget (ala Decburger), even if the callback isn't defined for it?? Alternatively, does anyone know how to get a create callback on an stext widget from from low level calls?

Create callbacks are a UIL/DRM concept. The widgets are not doing
the callback, DRM is. The basic idea is that DRM creates the
widget and then calls the callback. To the application, it pretty
much looks like any other callback, but the widget is not involved.

In addition to what Leo said, create callbacks aren't necessary if you are using the create routines. The main purpose of the create callbacks is to let the application know that a widget has been createed and what its id was. If you are using create routines, the application already knows that.

OK I got off on the create tangent trying to get a map callback in order to set focus to a widget on the first realization of it. I know the style guide doesn't like it, but customers ask to do it a lot and I'm trying to make a clean example using XtCallAcceptFocus instead of the current XSetFocus and a dummy simple window to get an expose callback to do the set focus. Any suggestions on a clean way to get focus set on initial invocation? Bruce | |||||
