Problems with ListView Scroll

[davidesalvetti]

Hi all,

I'm having some problems with ListView. I followed some exemples on the net but I can't scroll my list up and down. It's a basic list of buttons, but the height is more than the screen available, so I need to scroll down the item.

The code is the followiing:
list.qml

import QtQuick 2.11
import QtQuick.Controls 2.1
import QtQuick.Layouts 1.3

Rectangle{
    color: "red"

       Column {
           id: column
           anchors.fill: parent
            ListView{
                id: list
                anchors.top: column
                height: 3000
                //clip: true
                flickableDirection: Flickable.VerticalFlick
                boundsBehavior: Flickable.StopAtBounds
                interactive: true
                Button{
                    id: button1
                    anchors.top: column
                    height: 300
                    text: "Clicca Button 1"
                }
                Button{
                    id: button2
                    anchors.top: button1.bottom
                    height: 300
                    text: "Clicca Button 2"
                }
                Button{
                    id: button3
                    anchors.top: button2.bottom
                    height: 300
                    text: "Clicca Button 3"
                }
                Button{
                    id: button4
                    anchors.top: button3.bottom
                    height: 300
                    text: "Clicca Button 4"
                }
                Button{
                    id: button5
                    anchors.top: button4.bottom
                    height: 300
                    text: "Clicca Button 5"
                }
                Button{
                    id: button6
                    anchors.top: button5.bottom
                    height: 300
                    text: "Clicca Button 6"
                }
                Button{
                    id: button7
                    anchors.top: button6.bottom
                    height: 300
                    text: "Clicca Button 7"
                }
                Layout.fillWidth: true
                Layout.fillHeight: true

                ScrollBar.vertical: ScrollBar {}
            }
       }
}

I'm using a QWisget based application so I charge the qml in this way, just to be clear:

    QQuickView *rotella = new QQuickView();
    rotella->setResizeMode(QQuickView::SizeRootObjectToView);
    QWidget *container = QWidget::createWindowContainer(rotella, ui->page_3);
    container->setFocusPolicy(Qt::TabFocus);
    rotella->setSource(QUrl("qrc:/List.qml"));
    container->setGeometry(0,0, width, height);
    rotella->showMaximized();

The resul is this one:

What I'm trying to do is to scroll so that I can see also the other buttons.

Can anyone please help me?
Thanks in advance!

hi @davidesalvetti

your buttons are not part of the listview, they way you wrote it, they are children of the listview but not the model -> Flickable will not effect them.

I suggest the following:

Rectangle{
       color: "red"

        ListView{
            id: list
            anchors.fill: parent

            flickableDirection: Flickable.VerticalFlick
            boundsBehavior: Flickable.StopAtBounds
            interactive: true
           
            model: 7

            delegate:
                Button{
                    width:  list.width/2
                    height: 300
                    text: "Clicca Button " + (index +1)
                }
        }
    }
