Cannot clear selection in GridView/ListView

[Tobias Fensch]

Hello,

I want to clear the selection by clicking in the empty space of a GridView or ListView. I am using a a MouseArea that fills the GridView but is underneath the delegate items.

    GridView {
        id: gridViewNodes
        anchors.fill: parent
        cellWidth: root.isSmallLayout ? 108 : 140
        cellHeight: root.isSmallLayout ? 85 : 120
        clip: true
        highlightMoveDuration: 100
        reuseItems: true

        // unselect
        Item {
            anchors.fill: parent
            z: -1

            TapHandler {
                 // this is never been called
                onTapped: gridViewNodes.currentIndex = -1
            }
        }

This worked until I port my application to Qt 6.8.1. But now, the event handler is never reached.

Any suggestions?

cheers
Tobias

Qt 6 changed some input event handling, so you might need to adjust the event capturing logic.

So the solution is:

    GridView {
        id: gridViewNodes
        anchors.fill: parent
        cellWidth: 140
        cellHeight: 120
        clip: true
        highlightMoveDuration: 100
        reuseItems: true

        // unselect
        MouseArea {
            anchors.fill: parent
            propagateComposedEvents: true

            onClicked: (mouse) => {
                gridViewNodes.currentIndex = -1
                nodeListMultiSelectionHandler.resetSelection()

                mouse.accepted = false  // allow selection
            }
        }
