Detailed Description

Scrollable view. 

\qmltype ScrollView
\inherits Pane

! \instantiates 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.
