Item {
id: settingPage

ScrollView {
    anchors.fill: settingPage
    contentItem: settingPage
    clip: true
}

the scroll view should scroll it's own parent item?

Subuday

@raven-worx Yes, I want Setting Page to be scrolled.

Hi @Subuday , please have a look at the sample code:-

 Item  {
        id: settingPage

        height: 500
        width: 500
        anchors.centerIn: parent

        ScrollView {
            anchors.fill: settingPage
            //####Remove this
           //                contentItem: settingPage
            clip: true

            Label {
                text: "ABC"
                font.pixelSize: 1000
            }
        }
    }

Yes, I want Setting Page to be scrolled.

then the ScrollView can't be a child of the item supposed to be scrolled for obvious reasons.
I guess you rather want to make the ScrollView your component's root item instead?

Subuday

@raven-worx I try this code, but it also doesn't work.

    ScrollView {

        height: parent.height - menuBar.height - frame.height
        width: parent.width - toolBar.width
        anchors {
            top: menuBar.bottom
            left: toolBar.right
        }

        SettingPage {
            id: settingPage
            height: parent.height
            width: parent.width
            anchors.fill: parent
            visible: false
        }
    }

Setting Page

Item {
    id: settingPage

        Label {
            id: label
            text: "ABC"
            font.pixelSize: 1000
        }

        Rectangle {
            height: 100
            width: 100
            anchors.top: label.bottom
            color: "red"
        }

}

@Subuday

ellaborate on "but it also doesn't work."

height: parent.height
width: parent.width
anchors.fill: parent
visible: false

you are hiding your item. Also you anchor the scroll item to it's parent (same for width/height), which pretty much eliminates the need for scrolling at all.
Basically a ScrollView makes only sense when the content is bigger than the ScrollView itself.

@Shrinidhi-Upadhyaya Hi @Shrinidhi Upadhyaya, it works fine, but when I add rectangle in Setting Page, it doesn't.

Item {
    id: settingPage

    ScrollView {
        anchors.fill: settingPage
        clip: true

        Label {
            id: label
            text: "ABC"
            font.pixelSize: 1000
        }

        Rectangle {
            height: 100
            width: 100
            anchors.top: label.bottom
            color: "red"
        }
    }
}

sorry, but instead of arbitrarily trying random variations you should first take a look at the docs and the examples.
There can only be exactly ONE content item.

@raven-worx I make visible true,

Please, check the full code

@Subuday
you didnt change a single line of the ones i suggested...

ODБOï

@Subuday .., as said earlier , if your page is same size that your scrollView, nothing will scroll. you have to make the SettingPage bigger than the View + your page still has visible: false

Subuday

@LeLev Can I make Scroll View in Setting Page.
I try this, but it doesn't work.

Item {
    id: settingPage

    ScrollView {
        height: 100
        width: 100
        clip: true

        Rectangle {
            id: test
            height: 100
            width: 100

            Column {
                Text {
                    text: "ewfewf"
                    font.pointSize: 24
                }

                Text {
                 text: "ewkmfwef"
                 font.pointSize: 24
                }
            }

        }
    }
}

    SettingPage {
        id: settingPage
        height: parent.height - menuBar.height - frame.height
        width: parent.width
        anchors {
            top: menuBar.bottom
            left: toolBar.right
        }
        visible: true
    }

The suggestion of @LeLev works fine.
Thank you for help!
