我想模拟一本书的一页封闭。 有关如何在qml中执行此操作的任何建议吗?

或许Flipable
,结合Image
的{{3}}属性:
import QtQuick 2.0
import QtQuick.Window 2.0
Window {
id: window
width: 640
height: 480
visible: true
Image {
id: backgroundImage
source: "http://www.thebookdesigner.com/wp-content/uploads/2013/04/pages-vs-spreads.png"
anchors.centerIn: parent
Flipable {
id: flipable
anchors.fill: parent
anchors.leftMargin: parent.width / 2
property bool flipped: false
front: Image {
id: foldImage
source: backgroundImage.source
fillMode: Image.Pad
width: foldImage.implicitWidth / 2
horizontalAlignment: Image.AlignRight
}
back: Image {
source: backgroundImage.source
width: foldImage.implicitWidth / 2
fillMode: Image.Pad
horizontalAlignment: Image.AlignLeft
}
transform: Rotation {
id: rotation
origin.x: 0
origin.y: flipable.height / 2
axis.x: 0; axis.y: 1; axis.z: 0 // set axis.y to 1 to rotate around y-axis
angle: 0 // the default angle
}
states: State {
name: "back"
PropertyChanges {
target: rotation;
angle: -180
}
when: flipable.flipped
}
transitions: Transition {
NumberAnimation {
target: rotation
property: "angle"
duration: 1000
easing.type: Easing.InCubic
}
}
MouseArea {
anchors.fill: parent
onClicked: flipable.flipped = !flipable.flipped
}
}
}
}
Flipable
正如其名称所暗示的那样,fillMode
属性与width
相结合,对于整个图像而言太小,可让您“重新定位”图像的内容在该项目的范围内。
因此,front
项包含图像的右侧,back
项包含左侧。对于具有许多页面的实际书籍,您必须使用相关页面而不是相同页面。
