Receiving touch-events anywhere on the screen and then passing them on

[thealse]

I have a qt 5.8 / qml QtQuick 2.4 application for single touchscreen devices.

I would like to implement a function so that when the user has not touched anywhere on the screen for a certain time, the screen should dim down.

I don't know how to implement a handler that receives all touches anywhere on the screen and then passes them on, not even sure if it is possible!

I was thinking of putting a MouseArea covering the whole screen and then using the onPressed but I don't know to pass the touch-event on to the children underneath it.

For your screen mouse area, have you tried this?

    MouseArea {
        anchors.fill: parent
        onPressed:
        {
            // your stuff here, e.g. global timeout reset
            mouse.accepted = false;
        }
    }
