Set QApplication icon without using the rc/qrc file ?

[wysota]

If you set an icon, you have to load it into memory anyway and I'm sure you can spare few hundred bytes for a small png image. But if you don't want it that way, them simply create a QPixmap from file:

QApplication app(...);
app.setIcon(QPixmap("my_icon.xpm"));

QApplication app(...);
app.setIcon(QPixmap("my_icon.xpm"));
