MouseArea with different behaviour if Control-Key is pressed

maxwell31

Hi,

I have a Mouse area, and depending on whether modifier keys like alt or control are pressed, the behaviour should change. What is the best way to do this?

Have on mouse area and have clauses like

    if(Qt.ControlModifier)

Although my naive if clause does not even work in my example:

        MouseArea {
            anchors.fill: parent
            acceptedButtons: Qt.LeftButton
            onPressed: {
                    if(Qt.ControlModifier) {
                        recZoom.x = mouseX;
                        recZoom.y = mouseY;
                        recZoom.visible = true;
                    }
                }

Here the rectangle does not become visible if I press the Control key and the left button. How can I make this work? Also, if I have an item which comes with its own mouse area and is on top of this mouse area, how would this be handled?

Ok, the solution is probably here: http://doc.qt.io/qt-5/qml-qtquick-mouseevent.html

I tried

        mouse.modifiers & Qt.NoModifier

to test for no modifier keys but this does not work.

You need something like this

        onPressed: {
            if (mouse.modifiers & Qt.ControlModifier) {
                console.log("Mouse area pressed with control")
            }

missed it by that much :)
