QML: Avoid empty space when drag/drop between two views

[Diracsbracket]

Hi
I am using the QtQuick's Drag and Drop example (the Tiles part) to drag and drop tiles (representing buttons) from the list onto the grid as a way to dynamically lay out these buttons.

When "removing" (i.e. reparenting) the tile from the list, an empty space is left. I would like the list to automatically reorganize to close this gap. Is that possible using the approach in the example where the drag/drop is simply done by reparenting the tile?

Thanks for your help!

do you mean the red/blue source lists (on the left and right side)? If so these are Column types and you can call forceLayout() on them.

Yes, I mean those red tiles. I tried using your suggestion (the Column item's id is redSource) as in the snippet below, but this does not do anything? I put the call to forceLayout() in a StateChangeScript inside the drag.active state, but to no effect.

State {
    when: mouseArea.drag.active
    ParentChange { target: tile; parent: window.contentItem}

    StateChangeScript {
         name: "testScript"
          script: {console.debug("test"); redSource.forceLayout()}
   }

   AnchorChanges { target: tile; anchors.verticalCenter: undefined; anchors.horizontalCenter: undefined }
}
