QML PathView: change current index of pathview via mouse wheel
-
I have created a path view with a delegate and model. Is it possible to change current index of the PathView via mouse wheel instead of mouse click drag?
Following is my PathView code:
@PathView {
id: pathView;
anchors.fill: parent;
model: sampleModel;
delegate: delegate;
path: Path {
startX: 45; startY: 100
PathAttribute { name: "iconScale"; value: 0.3 }
PathAttribute { name: "iconOpacity"; value: 0.1 }
PathQuad { x: 45; y: 300; controlX: 45; controlY: 200 }
PathAttribute { name: "iconScale"; value: 1 }
PathAttribute { name: "iconOpacity"; value: 1 }
PathQuad { x: 45; y: 500; controlX: 45; controlY: 400 }
}

Hey,
i would go ahead and create a MouseArea where ever you need to catch the Mousewheel event. As you can see in the documentation, there is a onWheel(WheelEvent wheel) event.
bq. This handler is called in response to both mouse wheel and trackpad scroll gestures.
The wheel parameter provides information about the event, including the x and y position, any buttons currently pressed, and information about the wheel movement, including angleDelta and pixelDelta.Just create the notification in your MouseArea using onWheel: and handle it on your purpuses, that means increase or decreate the currentIndex of your PathView.
