Functionality in QIcon as well (iconWidget might get it from there). Since I 
am using KIcon, well, very easy!

Both myself and the original correspondent might have been best off starting 
with the iconWidget and that has a bona-fide clicked() signal! Without better 
docs, we start out with the sample code which is a bare applet subclass and no 
hints of other or added possibilities.
