## ScrollView
* single item: content size is automatically calculated based on the implicit size of its contained item.
* more than one item (or implicit size is not provided): the contentWidth and contentHeight must be set
* `ScrollView contentWidth: availableWidth` (this takes any padding or scroll bars into account)
* `Itemwidth: scrollView.availableWidth`
* Qt ScrollView has twitching bugs: [#5781](https://github.com/status-im/status-desktop/issues/5781)
* `contentItem` is a `Flickable`
Here's how `contentWidth` is calculated internally:
* [QQuickScrollViewPrivate::getContentWidth](https://codebrowser.dev/qt5/qtquickcontrols2/src/quicktemplates2/qquickscrollview.cpp.html#_ZNK23QQuickScrollViewPrivate15getContentWidthEv)
* [QQuickPanePrivate::getContentWidth](https://codebrowser.dev/qt5/qtquickcontrols2/src/quicktemplates2/qquickpane.cpp.html#_ZNK17QQuickPanePrivate15getContentWidthEv)

## Flickable
* contentWidth and contentHeight must be set
* size of the contentItem is determined by contentWidth and contentHeight.
* items are parented to Flickable's contentItem
* items cannot anchor to Flickable. Use parent, which refers to the Flickable's contentItem
* `Item width: parent.width`
