QML：如何在MouseArea上处理鼠标悬停事件？我可以提供一个简单的例子或说出我的错误吗？

Image {
    source: "quit.png"
    scale:  mouseArea.containsMouse ? 0.8 : 1.0
    smooth: quitMouse.containsMouse
    MouseArea {
        id: quitMouse
        anchors.fill: parent
        anchors.margins: -10
        onClicked: Qt.quit()
    }
}

   smooth: mouseArea.containsMouse
   MouseArea {
       id: mouseArea
       anchors.fill: parent
       anchors.margins: -10
