本文详细解析了Flipable组件的工作原理，包括其内部结构、关键属性及其如何通过交互实现组件翻转效果，并介绍了状态转换过程，以及如何在不同状态下调整组件的视觉效果。

Flipable {

    id: container

    property alias image: frontImage.source

    property bool flipped: true

    property int xAxis: 0

    property int yAxis: 0

    property int angle: 0

    width: front.width; height: front.height

    front: Image { id: frontImage; smooth: true }

    back: Image { source: "back.png"; smooth: true }

    state: "back"

    MouseArea { anchors.fill: parent; onClicked: container.flipped = !container.flipped }

    transform: Rotation {

        id: rotation; origin.x: container.width / 2; origin.y: container.height / 2

        axis.x: container.xAxis; axis.y: container.yAxis; axis.z: 0

    states: State {

        name: "back"; when: container.flipped

        PropertyChanges { target: rotation; angle: container.angle }

    transitions: Transition {

        ParallelAnimation {

            NumberAnimation { target: rotation; properties: "angle"; duration: 600 }

            SequentialAnimation {

                NumberAnimation { target: container; property: "scale"; to: 0.75; duration: 300 }

                NumberAnimation { target: container; property: "scale"; to: 1.0; duration: 280 }

}

在states中想直接对container的transform进行改变,这是办不到的,需要给相应的transform一个id,
然后在states中某一个State进行target定位属性变化,在transitions中使用target定位状态过渡.
