❝示例演示翻转动画(沿着x轴或y轴翻转动画)。❞
主要代码:
import QtQuick 2.0
Flipable {
id: container
property alias source: 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 }
back: Image { source: "back.png" }
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: 300 }
}
}
}
}
