I don't remember saying anything about member variables but that's only minor. I'll give you the gist of what I'm thinking of for a revision of the hierarchy. Nearly every one of the tiny little classes that implements some tiny *orthogonal* aspect of GUII is however dependent for whatever strange reason upon other classes. This has lead to the great big long vine we have. As I said, most of those classes are orthogonal and should instead be mixed-in as late as possible. Preferably directly into the final instance of either the controller or the view. What I dreamed up ages ago now (while I was scratching out a design for the StateMachineEngine) was a template-based final instanciation of most dialogs -- which turned out to be similar to the structures in use now except the equivalent of the ControlDialog class would have several more template parameters: one for each orthogonal aspect of connections, button-controller (StateMachineEngine) and anything else that should be mixed-in. I don't have the sketch with me now but I will endeavor to transfer the design to computer (probably a Dia file and some text) sometime soon. It may have to wait until after the Linux conference though (Feb. 6-9) as I have been neglecting my paid job and they want to see some action for their money. Allan. (ARRae) P.S. Oh dear, I've just peaked at some of my work and discovered all the Win2k images which get downloaded and installed on student machines here were wiped out on Friday evening... Lucky we backup.
