how to set size of buttons

843805Feb 15 2006 — edited Mar 6 2006
hi,
I am working on the GUI. There are four buttons. I wanted the button's width to be just enough to show the text inside the button and not "...." or bigger than required. How should I edit my code, which is shown below?

Thanks in advance

regards
