This is how I also envision that this works! As stated before I use this strategy in UFaceKit for QT and it works fantastic! The thing that still bothers me a bit for embedded devices is the huge amount of libraries we need at the level above SWT to parse CSS and interpret it appropriately and as outlined by Angelo Zerr the problem of notification about widget changes in SWT is a real problem! Some ideas to solve the problem with this programmatic notifications: a) Implement a marker interface listeners are notified in any case b) Add method addListener(int,Listener,boolean) where the boolean flag controls if the listener is called every time no matter if the change occurred because of a user interaction of programmatically by calling a method? c) Annotate the Listener with @listener(invoke="always"), @listener(invoke="user"), @listener(invoke="programmatic") I guess c) is not possible because it's Java5-Syntax and so I'd prefer b). Steve any idea from you how we could provide reaction to programmatic widget changes?
