各位高人：
我在listView里定义了model和delgate，把delegate的一个checkbox和mode的programEnabled绑定了，但是当checkbox发生变化时，model的值一直保持不变，请问这个是什么原因啊？
这个是读取model的函数
Button { id: buttonProgram text: qsTr("编程") function buttonProgramClicked() { var addrList = []; var itemCnt = listControlerModel.count; for (var i = 0; i < itemCnt; i++) { var tempModelItem = listControlerModel.get(i);
// programEnabled 不会根据视图上的值变化？？？？？ if(tempModelItem.programEnabled) { addrList.push(tempModelItem.ID); } } }
onClicked:buttonProgramClicked() }
这里是定义view，model，delgate的地方，其他的值都是对的，就是programEnabled不对
ListView { id: listControler width: 110 height: 160 anchors.top: parent.top// 这句话会让元素向上对齐，否则是居中对齐 anchors.topMargin: 0 Layout.fillWidth: true Layout.fillHeight: true clip:true // 设置为false会导致数据滑出窗外
model: ListModel { id: listControlerModel ListElement { ID: "1" type:"EVC41" SN: "12345" programEnabled:true colorCode: "black" // grey(off line) black(Not Check),pink(busy) red(Program Failed) green(Program OK) currentProgress:0 } ListElement { ID: "2" type:"EVC61" SN: "12346" programEnabled:true colorCode: "green" // grey(off line) black(Not Check) pink( busy )red(Program Failed) green(Program OK) currentProgress:100 } ListElement { ID: "3" type:"Unknow" SN: "Unknow" programEnabled:false colorCode: "pink" // grey(off line) black(Not Check) red(Program Failed) green(Program OK) currentProgress:50 } } Component { id: listControlerHead
