Apart from the fact that you can't expect a 64x64 icon to display properly on 
a 64x64 button when the style is taken into account...

...te fun thing about QIcon is that it ships the icons in the size and state 
the receiver wants it.
You want to look at 
http://doc.trolltech.com/4.5/qabstractbutton.html#iconSize-prop and then set 
the icon-size property on your pushbutton. This should a) make the icon in the 
size you want and b) adopt the size of the pushbutton to have the full icon, 
(optionally) the text and the full border and decoration from the style...

Have fun,

Arnold
