QSplitter becoming undistinguishable between QWidget and QTabWidget

Question

I am puting a QWidget and a QTabWidget next to each other in one horisontal splitter. And the splitter loses it\'s shape, you can know that there is a splitter only by hovering

Answer 1

This is true for every splitter at least with WinXP and the default Luna thema (changing to classic solves the problem). If you want to stay with Luna you may change the way the splitters are rendered, e.g. by changing the background color of the handle.

int main(int argc, char *argv[])    {

    QApplication a(argc, argv);
    a.setStyleSheet("QSplitter::handle { background-color: gray }");
    MainWindow w;
    w.show();
    return a.exec();
}
