0012  * @brief A background for Form delegates.

0014  * This is a simple background that provides opacity feedback to the user
0015  * when the control has focus or is currently being pressed, for example.
0016  *
0017  * This is used in AbstractFormDelegate so that new delegates provide this
0018  * feedback by default, and can be easily overriden with a QtQuick.Item.
