[Qt-interest] Qusetion about setIconSize() ?

[Jens Bache-Wiig]

Hi Kermit

QIcon normally only scales icons down and not up. Most likely to avoid 
the blurriness associated with upscaling images. If you need bigger 
icons than 48x48, you should add extra sizes to QIcon. Another 
alternative is to use an SVG-icon instead.
