I set the window title by
QWidget::setWindowTitle("test");
so the title of the window is "test". But in the taskbar it's displayed as "unknown". What's the correct way to set the taskbar name?
Edit:
I use Gnome3.4.2 and just found https://bugreports.qt-project.org/browse/QTBUG-22274. But for me there also the binary name isn't displayed; only "unknown".
EDIT2:
I tried it under Xfce and it worked.
