Detailed Description

Scrollable view.

\qmltype ScrollView
\inherits Pane

! \nativetype QQuickScrollView \inqmlmodule QtQuick.Controls

Since

5.9

ScrollView provides scrolling for user-defined content. It can be used to either replace a \l Flickable, or to decorate an existing one.

The first example demonstrates the simplest usage of ScrollView.

ScrollView {
    width: 200
    height: 200
 
    Label {
        text: "ABC"
        font.pixelSize: 224
    }
}

The second example illustrates using an existing \l Flickable, that is, a \l ListView.

ScrollView {
    width: 200
    height: 200
 
    ListView {
        model: 20
        delegate: ItemDelegate {
            text: "Item " + index
 
            required property int index
        }
    }
}

Note

As of Qt-6.0, ScrollView automatically clips its contents if you don't use a Flickable as a child. If this is not wanted, you can set your own Flickable as a child, and control the \l {Item::}{clip} property on the Flickable explicitly.
