I've seen in CVS head of some games of kdegames things like: #if QT_VERSION < 300 bottomGroup->setFontPropagation( QWidget::NoChildren ); bottomGroup->setPalettePropagation( QWidget::NoChildren ); #endif Can they be removed since KDE head should compile at least with QT 3.1 (i think it changed to 3.2 days ago) ?
