SwipeView swipes when it shouldn't

[VStevenP]

1. I have a SwipeView with 3 pages.
2. One page has a CustomKnob, which is simply an Image with a MouseArea filling it
3. You click and drag on the Image in the y direction to edit the knob. It works great, I change the knob image as I drag in Y and it looks good
4. Now, I'd like to have any click and drag in x on the Knob not pass to the SwipeView, because it should not pass through. I tried adding this to the MouseArea:

onMouseXChanged: {
mouse.accepted = true
}

This does not cause the SwipeView to ignore minor movement in X when swiping on the Knob in y

What can I do to get SwipeView to ignore X dragging on a child control? Normally these types of events do not propagate through a MouseArea. A parent widget will not act on it and treat it as a swipe gesture.

Qt 5.15.2

QML SwipeView

Here's some example code. How can it be changed so that clicking and dragging in the x direction on the orange square is ignored by the SwipeView?

import QtQuick 2.12
import QtQuick.Controls 2.5

ApplicationWindow {
id: appWindow
width: 640; height: 480
visible: true

SwipeView {
    id: swipeView
    anchors.fill: parent
    currentIndex: 1

    Rectangle {
        width: appWindow.width; height: appWindow.height
        color: "red"
    }

    Rectangle {
        width: appWindow.width; height: appWindow.height
        color: "green"

        Rectangle {
            width: 100; height: 100
            anchors.centerIn: parent
            color: "orange"

            MouseArea {
                anchors.fill: parent

                onMouseXChanged: {
                    mouse.accepted = true
                }
            }
        }
    }

    Rectangle {
        width: appWindow.width; height: appWindow.height
        color: "blue"
    }

} // end SwipeView

}

Setting MouseArea.preventStealing to true might work.

Hi jeremy_k,

Thanks for the idea.

I tried adding preventStealing: true to the MouseArea, but it didn't help.

I'm beginning to think there is no way to tell a SwipeView to not swipe when children controls are being clicked and dragged. That's a serious flaw that no one would want. I wonder if it ever worked properly.

Thanks again for your thoughts.
