How can I force a repaint of the screen ?

There is a update() method, maybe this is what you are searching for?

@import QtQuick 2.2

Rectangle {
width: 200
height: 200
Component.onCompleted: update()
}@

Otherwise you could connect a qml-signal to a cpp-slot which updates your qml.

Unfortunately not.
The update() only schdule for paint but not force it.

Hmm okay, in that case i would go for the signal-slot connection.
