我有一个树视图,通过动态创建可拖动项目,我可以将项目拖动到拖放区域。除了我无法通过mimedata外,一切正常
function createItem(parentItem)
{
if (itemComponent.status === Component.Ready && draggedItem == null)
{
draggedItem = itemComponent.createObject(
parentItem,
{
"x": positionInParent.x,
"y": positionInParent.y,
"baseColor":Qt.lighter("red", 1.5),
"copyable":false,
visible: true
}
);
draggedItem.Drag.mimeData = { "text/plain": "Hello!" };
draggedItem.Drag.supportedActions = Qt.CopyAction;
draggedItem.Drag.dragType = Drag.Automatic;
draggedItem.Drag.start();
}
else if (itemComponent.status === Component.Error) {
draggedItem = null;
console.log("error creating component");
console.log(itemComponent.errorString());
}
}
当我尝试从drop事件(drop.text字段)获取mime数据时,它是空的。
DropArea
{
height:parent.height
width:parent.width
onDropped: {
drop.acceptProposedAction()
var txt = drop.text; // Empty!!!
console.log("dropped into dest")
}
onEntered: {
console.log("entered dest")
}
}
答案 0 :(得分:0)
我自己解决了!只是添加
draggedItem.Drag.active = true;
