Is there a platform independent way to specify a fixed width font for a Qt widget ?
If I set the font to \"Monospace\" in Designer on Linux, it is not found on Windo
You can use the style hint property of QFont:
QFont font("Monospace"); font.setStyleHint(QFont::TypeWriter);
If the font cannot be found (which happens with Monospace on Windows), Qt's font matching algorithm tries to find a font that matches the given style hint.
