I stand corrected.  I had missed the cast.

The code snippet you posted invokes a well-known bug in the g++
parser, that, in this case, leads to the overload resolution error.

The well-known bugs page recommends replacing:

  QColorGroup q(QColor(QRgb(0))); // doesn't work

with

  QColorGroup q(QColor((0,QRgb(0)))); // doesn't work
                       ^^^       ^

This will help gcc parse it as an expression, as it should, not as a
declaration, as it does.
