PooyaSis

hi.
I have frameless QML application, when im resizing it, it flickers.
find this link in google
https://blog.rburchell.com/2011/11/avoiding-graphics-flicker-in-qt-qml.html

the problem is thas in my code i have

QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;

but in example there is

QApplication application(argc, argv);
QDeclarativeView view;

how Can i use
view.setAttribute(Qt::WA_OpaquePaintEvent);
view.setAttribute(Qt::WA_NoSystemBackground);
view.viewport()->setAttribute(Qt::WA_OpaquePaintEvent);
view.viewport()->setAttribute(Qt::WA_NoSystemBackground);

these with QQmlApplicationEngine???
is ther any equivalent for setAttribute in QQmlApplicationEngine?

I code in python, but I'm very sure you don't need to set any of those attributes. Completely do away with them and have something like:

QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
engine.load(QUrl("qrc:/qml/main.qml"));

I expect it to work, ok.

He needs it, read docs about these two attributes
