Hi Colin,

thanks for the hints.

After writing the initial mail it took me another 5 minutes to finally find 
QFontMetrics::elidedText() which does exactly what I want ^^

For my case:

  QGroupBox *group;
  QString filename;
  // ...
  QFontMetrics metrics(QFontMetrics(group->font());
  group->setTitle(metrics.elidedText(filename, Qt::ElideMiddle,
                                     group->width() * 0.75));

This gives a nice label 75% of the size of the widgets within the group box 
with the "middle part" of the filename omitted.

Cheers
