The trick is to retain references to every entry within the widget, but only embed it in the viewable area if it happens to be a valid entry at that point. Then all that's left is to hook events up to the proper callbacks that implement various actions of your custom widgets using what Tkinter is capable of doing. Personally I prefer to subclass Frame since it allows me the maximum flexibility (I think 90+% of the widgets I've written for my own Tkinter-based programs do this). All the best, Jason
