Re: Ugh! I am having trouble visualizing sizers.

Ugh! I thought I had mastered sizers and off to my next challenge, FONTs.

But not quite, I am hung up on making horizontal unstretchable.
Why would we want the Buttons to be unstretchable?
I would want the Buttons to stretch Horizontaly, if I dragged the Frame Horizontally.
Can someone explain this? Thanks! ...V

Please, see: Figure 7-8 A simple dialog using sizers
