[KDE/Mac] Fixing graphics problems in KDE/Qt on Apple OS X

[Ian Wadham]

Hi Marko,

This is a new problem, but hopefully not one we will see in a lot
of KDE apps. Please stick it in the wiki.

The progress thingy in the center of the diagram gets its background color from
http://api.kde.org/4.12-api/kdelibs-apidocs/kdeui/html/classKColorScheme.html
It is choosing colors for Active status in a Tooltip (usually yellow?). Visibility was
much improved when I inserted a line in the paintEvent() method of
kdeutils/filelight/src/part/progressBox.cpp, which said:

    paint.setPen(view.foreground().color());

The text then came out in white. The default pen is black. See bug report and patch at:

Cheers, Ian W.

P.S. Nice little utility that one!
