A ScrollView can be used either to replace a Flickable or decorate an existing Flickable . Depending on the platform, it will add scroll bars and a content frame.
Only one Item can be a direct child of the ScrollView and the child is implicitly anchored to fill the scroll view.
范例：
ScrollView {
Image { source: "largeImage.png" }
}
In the previous example the Image item will implicitly get scroll behavior as if it was used within a Flickable . The width and height of the child item will be used to define the size of the content area.
范例：
ScrollView {
ListView {
...
}
}
In this case the content size of the ScrollView will simply mirror that of its contained flickableItem .
You can create a custom appearance for a ScrollView by assigning a ScrollViewStyle .
