Detailed Description

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

A commen 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.

Member Function Documentation

[static] void QXcbWindowFunctions::​setWmWindowType(QWindow * window, WmWindowType type)

This is a convenience function that can be used directly instead of resolving the function pointer. window and type will be relayed to the function retrieved by QGuiApplication

[static] const QByteArray QXcbWindowFunctions::​setWmWindowTypeIdentifier()

This function returnes the bytearray that can be used to query QGuiApplication::platformFunction to retrieve the SetWmWindowType function.
