It's a while since I used tkinter, but if I recall correctly, the grid manager does allow proportional resizing. And you really don't need pack, you can use grid to do anything that pack can do. Having said that, experience has made me very skeptical about the usefulness of proportional resizing. Most often, there is one "main" content area in a window that I want to give the user control over the size of, and the other stuff around it can just as well be fixed size. When that's not true, proportional sizing doesn't really cut it -- you really need some kind of splitter control to let the user adjust the allocation of space according to the needs of the moment. -- Greg
