Create dummy MouseEvent in QML

[vikramg]

I have in my application a MouseArea for screensaver functionality:

    MouseArea {
        id: screenSaverTouchArea
        anchors.fill: parent
        onPressed: {
            var consumeEvent = false // Set to true to prevent propagation of touch
            . . . screen saver functionality . . .
            if (condition) {
                . . . 
                // Don't propagate touch here
                consumeEvent = true
            }
            . . .
            mouse.accepted = consumeEvent  // Set to false to propagate this event down
        }
    }

mouse.accepted is set based on whether I want the event to propagate down or not. Now I would also like the screen to be awakened from a different non-touch event in my app. The easiest way would be to call screenSaverTouchArea.onPressed() when that event happens:

function ssOnEvent() {
    screenSaverTouchArea.onPressed()
}

But that results in Error: Insufficient arguments. Is there a way to create a dummy MouseEvent in QML with some off-screen x/y touch coordinates and call the onPressed handler with that as the argument?
