How to pass `QQuickWheelEvent` to C++?

[kaixoo]

I've setup a QQuickFramebufferObject and now I'm trying to receive input from it. How do you pass events (like QML WheelEvent) to C++ code?

MouseArea {
    anchors.fill: parent
    z: 999

    onClicked: (event) => appCanvas.onClicked(event)

and then, in C++..

        Q_INVOKABLE void onClicked(QMouseEvent* event);

Which doesn't seem to work:

"Could not convert argument 0 from QQuickMouseEvent(0x57f228370c48) to QMouseEvent*"

TypeError: Passing incompatible arguments to C++ functions from JavaScript is not allowed.

@kaixoo
I am not a QMLer, but Can qml signal parameter MouseEvent be mapped to C++ class? suggests you should just explicitly pass those members you are interested in.

Oh, I need all of them :(

Hi,
One thing you could do is create a small wrapper class so you don't have a big function signature.
