/**
 * A ruler widget.
 *
 * The vertical ruler looks similar to this:
 *
 *\code
 *    meters                       inches
 *
 *    ------   <--- end mark  ---> ------
 *        --                            -
 *        --   <---little mark--->     --
 *        --                            -
 *        --                          ---
 *       ---   <---medium mark          -
 *        --                           --
 *        --        tiny mark---->      -
 *        --                         ----
 *        --                            -
 *      ----   <-----big mark          --
 *        --                            -
 *      |>--   <--ruler pointer-->   |>--
 *
 * \endcode
 *
 * There are tiny marks, little marks, medium marks, and big marks along the
 *  ruler.
 *
 * To receive mouse clicks or mouse moves,
 * the class has to be overloaded.
 *
 * For performance reasons, the public methods don't call QWidget::repaint().
 * (Slots do, see documentation below.)
 * All the changed settings will be painted once after leaving
 * to the main event loop.
 * For performance painting the slot methods should be used,
 * they do a fast QWidget::repaint() call after changing the values.
 * For setting multiple values like minValue(), maxValue(), offset() etc.
 * using the public methods is recommended
 * so the widget will be painted only once when entering the main event loop.
