[讨论]Drag & Drop 过程中，源Item被释放（析构）程序出错 [复制链接]

如题。 现在拖动的Item 在放到Drop区前，动态地被析构了，必然会引起程序崩溃。

是我用法不对还是有什么方案可以解决的？

import QtQuick 2.0
import QtQuick.Controls 1.3

Rectangle {
    id: container
    property int counter: 1
    width: 600; height: 600

    Timer{
        interval: 10000
        repeat: true
        running: true
        onTriggered: container.counter++;
    }

    Repeater{
        model: container.counter
        Rectangle {
            id: iddragblock
            width: 50; height: 50
            y: 54 * index
            x: 54 * index
            color: "red"
            Drag.active: idmousearea.drag.active
            Drag.dragType: Drag.Automatic
            MouseArea {
                id:idmousearea
                anchors.fill: parent
                drag.target: iddragblock
            }
        }
    }
}

试验代码如上。只要使用了Automatic， 触发Drag后保持按着不动，等源Item被释放后，松开鼠标就会出错。

When using Drag.Automatic you should also define mimeData and bind the active property to the active property of MouseArea : MouseArea::drag.active
