[static] void QXcbWindowFunctions::setWmWindowIconText(QWindow *window, const QString &text)

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

[static] const QByteArray QXcbWindowFunctions::setWmWindowIconTextIdentifier()

This function returns the byte array that can be used to query QGuiApplication::platformFunction to retrieve the SetWmWindowIconText function.

[static] void QXcbWindowFunctions::setWmWindowRole(QWindow *window, const QByteArray &role)

Sets the WM_WINDOW_ROLE property from role on the corresponding X11 window.

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