That is very likely ;)  I now also understand that all these objects would be allowed to do drawing for the widget they are connected to, etc.

Still it is a very good idea to get some prototyping going to get a feel for this and to see how much code it would save in the end.  I like the examples put forward by Federico: GtkButton/GtkScrollbar and text selection.

If one would do *real* MVC, then something like a GtkButtonView does make sense and is definitely not useless.  The point is then that you have different implementations of GtkButtonView for e.g. normal displays, small displays, touch screen/tablet.  You would also have different implementations of a GtkButtonController according to the input method used (mouse vs. touchscreen is a good example).
