I am using Qt 5.6 & above. I have a QQuickItem sub-class which is placed in my main.qml

class MyQQuickItem : public QQuickItem {

}

In my main.cpp I register MyQQuickItem using qmlRegisterUncreatableType. It displays fine on the app main UI screen.

Now, I have a valid texture which is QOpenGLFramebufferObject. I just want to display this QOpenGLFramebufferObject on the UI of MyQQuickItem.

Probably I should call update on MyQQuickItem somehow providing this texture to it ? How can do this?

By implementing `updatePaintNode` and returning some scenegraph nodes that draw your texture. In case, did you consider to use QQuickFramebufferObject directly instead? – peppe Feb 22 '17 at 17:55
@peppe How can I use `QOpenGLFramebufferObject` directly ? any examples you can point me to ? – TheWaterProgrammer Feb 22 '17 at 18:07
is there a way to trigger `updatePaintNode` manually ? – TheWaterProgrammer Feb 23 '17 at 08:23
