我想要一个 Swipeview，在一个 swipeview 中列出一个小部件（按钮）。一切都必须动态创建，因为可以有一个或五个屏幕，或者一个或多个小部件。它可以通过抽屉添加（将来）。在抽屉上添加屏幕会增加一个屏幕。添加小部件在当前屏幕上添加一个小部件。我觉得应该和图片一样。我试图让这个像这里一样。 概念 我的尝试：

main.qml

ApplicationWindow {
visible: true
Item {
    id: root

    ListModel {
        id: listoflists
    }

    ListView {
        id: listview 
    }

    function addlist() {
        CreateObject.create("listofwidgets.qml", root, itemAdded);
    }

    function listadded(obj, source) {
        listoflists.append({"obj": obj, "source": source})
    }

    function addview() {
        CreateObject.create("view.qml", root, itemAdded);
    }

    function viewadded(obj, source) {
        listoflists.append({"obj": obj, "source": source})
    }

}

Component {
    id: modelDelegate
        Text {
            text: name
        }
}

SwipeView {
    id: view
    currentIndex: 0

}

PageIndicator {
    id: indicator

    count: view.count
    currentIndex: view.currentIndex

    anchors.bottom: view.bottom
    anchors.horizontalCenter: parent.horizontalCenter
}

Button {
    width: parent.width
    height: 20
    text: "add screen"

    onClicked: {
        addlist()
        addview()
    }
}

Button {
    width: parent.width
    height: 20
    text: "add widget"

    onClicked: {
         listoflist.get(view.currentIndex).addwidget()
    }
}
}

listofwidgets.qml

Item {
id: root2

ListModel {
    id: listofwidgets
}

function addwidget() {
    CreateObject.create("widget.qml", root2, widgetadded);
}

function widgetadded(obj, source) {
    listofwidgets.append({"obj": obj, "source": source})
}

}

小部件.qml

ListElement {
    name: ""
}

视图.qml

Item {
id: view.currentIndex

ListView {
    model: listoflists.get(view.currentIndex)
    delegate: modelDelegate

}
}

我不知道您是否需要，但这里是完全动态创建的示例SwipeView：

import QtQuick 2.7
import QtQuick.Window 2.2
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.3

Window {
    width: 400
    height: 600
    visible: true

    ColumnLayout {
        anchors.fill: parent
        spacing: 2
        Rectangle {
            Layout.preferredHeight: 50
            Layout.fillWidth: true
            Row {
               Button {
                   text: "Add screen"
                   onClicked: addScreen();
               }
               Button {
                   text: "Add widget"
                   onClicked: addWidget();
               }
            }
        }

        SwipeView {
            id: swipe
            Layout.fillWidth: true
            Layout.fillHeight: true
        }
    }

    Component {
        id: screenComponent
        Rectangle {
            property alias view: view
            color: Qt.rgba(Math.random(),Math.random(),Math.random(),1)
            ListView {
                id: view
                spacing: 2
                anchors.fill: parent
                model: ListModel {}
                delegate: widgetComponent
            }
        }
    }
    Component {
        id: widgetComponent
        Button {
            text: name + "_" + index
        }
    }

    function addScreen()
    {
        var page = screenComponent.createObject(swipe);
        swipe.addItem(page);
        swipe.currentIndex = swipe.count - 1;
    }

    function addWidget()
    {
        var page = swipe.currentItem;
        if(page) {
            page.view.model.append({name: "widget"});
        }
    }
}
