I know about the Bin, but I guess I didn't made myself clear. I'm Sorry, I'll try to explain: I would like to have a way to create composite widgets without exposing the base Container methods (Let's say I used a box... it would have the box's methods and all the GtkContainer methods... and I wouldn't like client code to call gtk_container_add on a widget that is not supposed to "mean" a container) So, I would like to create an as-simple-as-it-gets container that descended only from GtkWidget so that it wouldn't really have methods to act like a container (Its only child widget would be set as a constructor parameter and overrided by its descendants). That way I could compose a widget using a table, a box or whatever layout containers and pack it inside a class, derived from that one I described above, that would only export the methods needed to the users (the GtkWidget methods and the specific Widget methods). Is there a better way to achieve this ? The only thing I could thought of was this "Basic Dumb Container" but I know it looks really bad. Is there a way to make a composite widget without exporting all those nasty GtkContainer and other containers methods ?
