在win10中，使用qml实现屏幕翻转，屏幕是触屏。

在 Win10 中使用 QML 实现屏幕翻转并支持触摸屏，可以按照以下步骤进行：

1. 在 QML 中，可以通过 `Screen` 对象获取屏幕的宽度和高度，并通过 `Rotation` 对象实现屏幕翻转。

import QtQuick.Window 2.12
import QtQuick.Controls 2.12

Window {
    id: rootWindow
    visible: true
    width: Screen.width
    height: Screen.height
    title: "Screen Rotation"

    Rectangle {
        id: rect
        width: Screen.width
        height: Screen.height
        color: "red"

        Rotation {
            id: rotation
            origin {
                x: rect.width / 2
                y: rect.height / 2
            }
            angle: rootWindow.orientation === Qt.PortraitOrientation ? 90 : -90
            axis { x: 0; y: 0; z: 1 }
            Behavior on angle { NumberAnimation { duration: 250 } }
        }
    }

    function updateOrientation() {
        switch (Screen.primaryOrientation) {
        case Screen.PortraitOrientation:
            rootWindow.orientation = Qt.PortraitOrientation
            break
        case Screen.LandscapeOrientation:
            rootWindow.orientation = Qt.LandscapeOrientation
            break
        case Screen.InvertedPortraitOrientation:
            rootWindow.orientation = Qt.InvertedPortraitOrientation
            break
        case Screen.InvertedLandscapeOrientation:
            rootWindow.orientation = Qt.InvertedLandscapeOrientation
            break
        }
    }

    Component.onCompleted: {
        Screen.primaryOrientationChanged.connect(updateOrientation)
        updateOrientation()
    }
}

2. 为了支持触摸屏，可以在 `Rectangle` 中添加一个 `MouseArea`，并在 `onPressed` 信号中获取触摸点的位置，并将其与屏幕宽度和高度比较，以确定是否进行屏幕翻转。

import QtQuick.Window 2.12
import QtQuick.Controls 2.12

Window {
    id: rootWindow
    visible: true
    width: Screen.width
    height: Screen.height
    title: "Screen Rotation"

    Rectangle {
        id: rect
        width: Screen.width
        height: Screen.height
        color: "red"

        Rotation {
            id: rotation
            origin {
                x: rect.width / 2
                y: rect.height / 2
            }
            angle: rootWindow.orientation === Qt.PortraitOrientation ? 90 : -90
            axis { x: 0; y: 0; z: 1 }
            Behavior on angle { NumberAnimation { duration: 250 } }
        }

        MouseArea {
            anchors.fill: parent
            onPressed: {
                if (mouseX < Screen.width / 2 && mouseY < Screen.height / 2) {
                    rootWindow.orientation = Qt.InvertedLandscapeOrientation
                } else if (mouseX < Screen.width / 2 && mouseY > Screen.height / 2) {
                    rootWindow.orientation = Qt.LandscapeOrientation
                } else if (mouseX > Screen.width / 2 && mouseY < Screen.height / 2) {
                    rootWindow.orientation = Qt.InvertedPortraitOrientation
                } else if (mouseX > Screen.width / 2 && mouseY > Screen.height / 2) {
                    rootWindow.orientation = Qt.PortraitOrientation
                }
            }
        }
    }

    function updateOrientation() {
        switch (Screen.primaryOrientation) {
        case Screen.PortraitOrientation:
            rootWindow.orientation = Qt.PortraitOrientation
            break
        case Screen.LandscapeOrientation:
            rootWindow.orientation = Qt.LandscapeOrientation
            break
        case Screen.InvertedPortraitOrientation:
            rootWindow.orientation = Qt.InvertedPortraitOrientation
            break
        case Screen.InvertedLandscapeOrientation:
            rootWindow.orientation = Qt.InvertedLandscapeOrientation
            break
        }
    }

    Component.onCompleted: {
        Screen.primaryOrientationChanged.connect(updateOrientation)
        updateOrientation()
    }
}

这样，就可以在 Win10 中使用 QML 实现屏幕翻转并支持触摸屏了。
