qml中垂直Listview内的水平listView

Question

我想使一个水平listView作为另一个veritcal listView的委托,我写了下面的代码:

import Qt 4.7

Item {
    id:main
    width: 360
    height: 640

    Component{
        id:myDelegate
            ListView{
                id:list2
                spacing: 5
                width:list.width
                height:list.height/3
                interactive: true
                orientation: ListView.Horizontal
                model: ListModel {
                    ListElement {
                        name: "Bill Smith"
                        number: "555 3264"
                    }
                    ListElement {
                        name: "John Brown"
                        number: "555 8426"
                    }
                    ListElement {
                        name: "Sam Wise"
                        number: "555 0473"
                    }

                    ListElement {
                        name: "Sam Wise"
                        number: "555 0473"
                    }

                    ListElement {
                        name: "Sam Wise"
                        number: "555 0473"
                    }
                }
                delegate: Text{text:name
                width: main.width/3}

                focus: true
                MouseArea {
                    anchors.fill:  parent
                    onClicked: {
                        ListView.list2.currentIndex = ListView.list2.indexAt(mouseX, mouseY)
                    }
                }

            }
    }

    ListView {
        id: list
        clip: true
        spacing: 5
        anchors.fill: parent
        orientation: ListView.Vertical
        model: Model{}
        delegate:myDelegate

//        highlight: Rectangle {
//            width: list.currentItem.width
//            color: "lightsteelblue"
//            radius: 5
//        }
        focus: true
        MouseArea {
            anchors.fill:  parent
            onClicked: {
                list.currentIndex = list.indexAt(mouseX, mouseY)
            }
        }
    }
}

垂直列表视图滚动得很好但水平列表不滚动.有帮助吗？谢谢

Answer 1

我尝试了一次它没有用,外部列表处理所有事件.解决方案是在ListViews之外还有一个Flickable,并将垂直列表的水平和contentY的contentX锚定到Flickable的contentX和contentY.

一些半完整的代码来说明原理:

Item {

    ListView {

        anchors.fill: parent
        clip: true
        orientation: ListView.Vertical
        interactive: false
        contentY: listController.contentY
        delegate: ListView {
             orientation: ListView.Horizontal
             interactive: false
             contentX: listController.contentX
        }

    }

    Flickable {
        id: listController
        anchors.fill: parent
        contentHeight: vert.contentHeight
        contentWidth: horizontalElement.width
    }

}

我在模拟器上尝试了这个解决方案，它奏效了。

import QtQuick 1.1
import com.nokia.symbian 1.1

Page {
    id: mainPage
    anchors.fill: parent


    ListModel {
        id: colorsModel
        ListElement {
            colorCode: "red"
        }
        ListElement {
            colorCode: "green"
        }
        ListElement {
            colorCode: "blue"
        }
        ListElement {
            colorCode: "orange"
        }
        ListElement {
            colorCode: "white"
        }
        ListElement {
            colorCode: "purple"
        }
        ListElement {
            colorCode: "gray"
        }
        ListElement {
            colorCode: "yellow"
        }
        ListElement {
            colorCode: "purple"
        }
    }

    ListView {
        anchors.fill: parent
        model: 30
        spacing: 20
        cacheBuffer: 200 // in pixels

        delegate:
            ListView {
            width: parent.width;
            height: 50;

            spacing: 20
            model: colorsModel
            orientation: ListView.Horizontal
            delegate:
                Rectangle {
                color: colorCode
                width: 50
                height: 50

                MouseArea {
                    anchors.fill: parent
                    onClicked: {
                        console.log(colorCode + " clicked");
                    }
                }
            }
        }
    }
}
