Detailed Description

       A class representing a scale division.

       A scale division consists of its limits and 3 list of tick values qualified as major,
       medium and minor ticks.

       In most cases scale divisions are calculated by a QwtScaleEngine.

Constructor & Destructor Documentation

   QwtScaleDiv::QwtScaleDiv (const QwtDoubleInterval &interval, QwtValueListticks[NTickTypes])
       [explicit]
       Construct QwtScaleDiv instance.

       Parameters:
           interval Interval
           ticks List of major, medium and minor ticks

   QwtScaleDiv::QwtScaleDiv (doublelowerBound, doubleupperBound, QwtValueListticks[NTickTypes])
       [explicit]
       Construct QwtScaleDiv instance.

       Parameters:
           lowerBound First interval limit
           upperBound Second interval limit
           ticks List of major, medium and minor ticks

Member Function Documentation

   bool QwtScaleDiv::contains (doublevalue) const
       Return if a value is between lowerBound() and upperBound()

       Parameters:
           value Value

       Returns:
           true/false

   QwtDoubleInterval QwtScaleDiv::interval () const [inline]
       Returns:
           lowerBound -> upperBound

   double QwtScaleDiv::lowerBound () const [inline]
       Returns:
           lower bound

       See also:
           upperBound()

   int QwtScaleDiv::operator!= (const QwtScaleDiv &s) const
       Inequality. Returns:
           true if this instance is not equal to s

   int QwtScaleDiv::operator== (const QwtScaleDiv &other) const
       Equality operator. Returns:
           true if this instance is equal to other

   double QwtScaleDiv::range () const [inline]
       Returns:
           upperBound() - lowerBound()

   void QwtScaleDiv::setInterval (doublelowerBound, doubleupperBound) [inline]
       Change the interval

       Parameters:
           lowerBound lower bound
           upperBound upper bound

   void QwtScaleDiv::setInterval (const QwtDoubleInterval &interval)
       Change the interval

       Parameters:
           interval Interval

   void QwtScaleDiv::setTicks (inttype, const QwtValueList &ticks)
       Assign ticks

       Parameters:
           type MinorTick, MediumTick or MajorTick
           ticks Values of the tick positions

   const QwtValueList & QwtScaleDiv::ticks (inttype) const
       Return a list of ticks

       Parameters:
           type MinorTick, MediumTick or MajorTick

   double QwtScaleDiv::upperBound () const [inline]
       Returns:
           upper bound

       See also:
           lowerBound()
