Qml里如何弹出警告消息

1、右侧信息弹窗使用PropertyAnimation来控制窗体的opacity透明度和Y坐标 就可以实现弹窗效果了

2、PropertyAnimation{ id: hideAnimation target: subWindow properties:"opacity" from: 1.0

3、 to: 0.0 duration: 300 onStopped: { subWindow.visible = false; } }

4、 PropertyAnimation{ id: downAnimation target: subWindow properties:"y" from: root.y to: root.y + 24 duration: 300 }

6、把loader的asynchronous属性设置为true的时候，会报错”Object destroyed during incubation”
