[Newbies] Button Wow Factor

[joe biggins]

Hi,

Ive been writing a program using simpleButtonMorphs, now everything is
working I am trying to tweek the look and feel.  How do I get the same
buttons as appear in the squeak dialogue boxes (the ones with the two
shades of gray that change colour when you roll over them, instread of
the plain old boring simpleButtomMorph?  Can these other buttons be
subtyped? (I have been subtyping the simpleButton to give me an extra
finctionality)

Many thanks
