Hi all. I'm creating a new widget class using Tkinter (class inherited form Tkinter.Frame). This class creates a bunch of other widgets inside it that can be "gridded" either horizontally or vertically. I would like to provide the user of the class an option to change this layout on the fly, using something like "widget[ 'layout' ] = 'vertical'". Does anyone have experience with that? I'm afraid i just down know how to proceed or where to look for an example. thx for any help. alex.
