Detailed Description

The QXcbWindowFunctions class is an inline class containing miscellaneous functionality for xcb window specific functionality.

A common usage pattern is as follows:

int main(int argc, char **argv)
{
    QApplication app(argc, argv);

    QPushButton topLevelWidget("Hello World!");
    topLevelWidget.winId(); //have to create the QWindow

    QWindow *tlwWindow = topLevelWidget.windowHandle();

    QXcbWindowFunctions::setWmWindowType(tlwWindow, QXcbWindowFunctions::Dock);

    topLevelWidget.show();

    return app.exec();
}

Note: There is no binary compatibility guarantee for this class, meaning that an application using it is only guaranteed to work with the Qt version it was developed against.
