It is quite apparent that the label is holding a local copy. In theory you should be able to cast a button widget as a gtklabel and then use gtk_label_set to change the caption of a button for instance. But I have tried just about every thing and cannot get it to work.

As long as PChar keeps the same address, you will see the change in the variable. Shane >>> Cliff Baeseman 04/21 3:54 PM >>> I was thinking about this the other night a little. GTK uses pchar or pointer to characters. If I change the PChar does the label change dynamically if the pchar changes? I have not tried it so I do not really know if it will or not. This would really clean things up a bit. Else I believe I would just create the group on the lower end much like I do with the menu system.

However, the "group" property doesn't exist in TControl or TWinControl so either I have to create one (which is kind of a waste because nothing else uses it) or I have to actually create the component in the TRadioButton class. If I create the component in the TRadioGroup class, then how do I know when to destroy it and re-construct it when , for example, the caption changes? See if the caption changes, the radiobutton has to be recreated because gtk doesn't give you the ability to simply change the label for a radiobutton. You have to set the label when you create it. So, should I move "group" all the way down, or is there a way (?virtual function?) to notify a child class of a change caused by the parent .............Can TControl call something in TRadioButton....
