\brief A frame control.
Frame is used to layout a logical group of controls together, within a
visual frame. Frame does not provide a layout of its own, but requires
you to position its contents, for instance by creating a \l RowLayout
or a \l ColumnLayout.
If only a single item is used within a Frame, it will resize to fit the
implicit size of its contained item. This makes it particularly suitable
for use together with layouts.
### TODO: screenshot
\code
Frame {
ColumnLayout {
anchors.fill: parent
CheckBox { text: qsTr("E-mail") }
CheckBox { text: qsTr("Calendar") }
CheckBox { text: qsTr("Contacts") }
}
