Below is a sample program that uses the old SunView API for creating a button
along with the XView API to create the same thing. Now, since the old mannar
provides a means of passing a font as an argument to the create call I can
set any font & size I like and everything works fine. My question is...Will
the next version of XView provide the same capability or has this function
just been left in for compatability reasons? Also using the old SunView renders
a rectangle type of button and the default XView renders the oval type of
button. Is there a way other than what I have here to render the same type of
rectangle button using XView? The rectangle button looks nicer.
