-/*!
- \class QRubberBand
- \brief The QRubberBand class provides a rectangle or line that can
- indicate a selection or a boundary.
-
- A rubber band is often used to show a new bounding area (as in a
- QSplitter or a QDockWidget that is undocking). Historically this has
- been implemented using a QPainter and XOR, but this approach
- doesn't always work properly since rendering can happen in the
- window below the rubber band, but before the rubber band has been
- "erased".
-
- You can create a QRubberBand whenever you need to render a rubber band
- around a given area (or to represent a single line), then call
- setGeometry(), move() or resize() to position and size it. A common
- pattern is to do this in conjunction with mouse events. For example:
-
- \snippet doc/src/snippets/code/src_gui_widgets_qrubberband.cpp 0
-
- If you pass a parent to QRubberBand's constructor, the rubber band will
- display only inside its parent, but stays on top of other child widgets.
- If no parent is passed, QRubberBand will act as a top-level widget.
-
- Call show() to make the rubber band visible; also when the
- rubber band is not a top-level. Hiding or destroying
- the widget will make the rubber band disappear. The rubber band
- can be a \l Rectangle or a \l Line (vertical or horizontal),
- depending on the shape() it was given when constructed.

- change this and call QWidget::setWindowOpacity() to make a
