zhengtianzuo系列-Qml上拉下拉刷新
当ListView拉动到一定位置的时候 就需要出现Loading 然后加载数据进行刷新
所以我们通过states来进行拉动位置的判断
``` ListView { id: listView width: parent.width height: parent.height model: listModel delegate: Rectangle{ height: 24 width: parent.width border.color: "#AAAAAA" border.width: 1 Text { font.family: "microsoft yahei" font.pixelSize: 15 anchors.centerIn: parent text: name + ": " + number } } states: [ State { id: downRefresh name: "downRefresh"; when: (listView.contentHeight > 0) && (listView.contentY > (listView.contentHeight - root.height + nPullHeight)) StateChangeScript { name: "funDownRefresh" script: funDownRefresh() } }, State { id: upRefresh name: "upRefresh"; when: (listView.contentY < -nPullHeight) StateChangeScript { name: "funUpRefresh" script: funUpRefresh() } } ] } ```
