Also use the xmanager to dispatch the events of these child-widgets to a specific procedure. More or less, it worked. Absolutely, i well change all parts of my system into oo-based step by step.

Well, I would advise you to do it sooner rather than later. The problem
you are going to have very, very soon now is that information you need
to do something useful in your event handler procedure is going to be
stored in the program object and will be unavailable to you in your
event handler procedure. Then you are going to wish (desperately, I
should think!) that you had assigned your widget object an event handler
method, where information from the ENTIRE program is available to it.
:-)

Cheers,
