实现 QMl MouseArea鼠标悬浮效果

    Rectangle

    {

        width: 100

        height: 200

        color: "grey"

        MouseArea

        {

           hoverEnabled: true

            anchors.fill: parent

            onEntered: {console.log("111111111111")}

            onExited: {console.log("22222222222222")}

        }

    }

 hoverEnabled: 默认设置是false,必须设置为true.  onEntered   onExited信号才起作用。否则效果不会出现
