    \brief A group box control.

    GroupBox is used to layout a logical group of controls together, within
    a titled visual frame. GroupBox 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 GroupBox, 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
    GroupBox {
        title: qsTr("Synchronize")
        ColumnLayout {
            anchors.fill: parent
            CheckBox { text: qsTr("E-mail") }
            CheckBox { text: qsTr("Calendar") }
            CheckBox { text: qsTr("Contacts") }
