Actually for what I did, I wanted the absolute pixel placement. That worked out fine for me in that instance. However that's not to say I'd use that every time. I'd have to look at the app I was building.

I used that technique with the first Tk app I ever did, and the ability to place things at x-y coordinates was easier for me to deal with for what I did as I had some graphics in my main window. I used Photoshop since I was more comfortable with it than Paint Shop Pro.

It worked for me, it might not for others. I only offered it as a suggestion as the o.p. seemed to be looking for an easy solution for laying out widgets in Tk.
