[Boa Constr] Newbie question: How do you get a button to size itself according the its text?

[Don T. <nos...@gm...>]

I have set wx.BU_EXACTFIT, but that is clearly not enough.

I guess that some combination of Size, BestFittingSize, ClientSize, 
MaxSize, MinSize and SizeHints drives this but I don't understand what 
these things do.

When I do try to change some of these settings to (-1, -1) then the 
change does stick, or else requires two or three tries at the same 
settings before it sticks.

Thanks in advance for your help.

Don.
