Hi.
I have 2 windows in my app.
When I use drag and drop in one window - all work fine.
But I can't get drop signal in second windows. And mouse icon showing drap only in one window.

        Tree {
        
                    id: tree
        
                    filterClassType: [ EnumsLibrary.objectTypes.TDevice, EnumsLibrary.objectTypes.TModule, EnumsLibrary.objectTypes.TSensor ]
        
                    headerVisible: false
        
                    autoExpand: false
        
        
        
                    itemDelegate: Item {
        
                        id: objectTree
        
        
        
                        Text {
        
                            id: objectTreeName
        
                            property var params: styleData.value
        
                            property string type: "tree"
        
                            anchors.verticalCenter: parent.verticalCenter
        
                            anchors.left: parent.left
        
                            color: "black"
        
                            elide: styleData.elideMode
        
                            text: styleData.value['Name'] !== undefined ? styleData.value['Name'] : "ИМЯ НЕ УСТАНОВЛЕНО"

@Mihaill need using

                    Item {
                                    id: draggable
                                    anchors.fill: parent
                    Drag.dragType: Drag.Automatic
//                    Drag.keys: [ "any" ]
                    Drag.active: mouseAreaTree.drag.active
                    Drag.hotSpot.x: 1
                    Drag.hotSpot.y: 10
                    Drag.mimeData: params
//                    Drag.mimeData: {"text/plain": "Copied text"}
                    Drag.onActiveChanged: {
                        console.log("444444444444444444444444444444444444", Drag.active)
                        if (Drag.active) {
//                            Drag.imageSource = "qrc:/assets/add_window.svg"
                        } else {
                            Drag.drop()
                        }
                    }
                    }
