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 () [explicit]
       Construct an invalid QwtScaleDiv instance.

   QwtScaleDiv::QwtScaleDiv (const QwtInterval &interval, QList< double >ticks[NTickTypes]) [explicit] Construct
       QwtScaleDiv instance.
       Parameters:
           interval Interval
           ticks List of major, medium and minor ticks

   QwtScaleDiv::QwtScaleDiv (doublelowerBound, doubleupperBound, QList< double >ticks[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

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

   void QwtScaleDiv::invalidate ()
       Invalidate the scale division.

   void QwtScaleDiv::invert ()
       Invert the scale divison.

   bool QwtScaleDiv::isValid () const
       Check if the scale division is valid.

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

       See also:
           upperBound()

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

   bool 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 (const QwtInterval &interval) Change the interval
       Parameters:
           interval Interval

   void QwtScaleDiv::setInterval (doublelowerBound, doubleupperBound) [inline] Change the interval
       Parameters:
           lowerBound lower bound
           upperBound upper bound

   void QwtScaleDiv::setTicks (inttype, const QList< double > &ticks) Assign ticks
       Parameters:
           type MinorTick, MediumTick or MajorTick
           ticks Values of the tick positions

   const QList< double > & QwtScaleDiv::ticks (inttype) const Return a list of ticks
       Parameters:
           type MinorTick, MediumTick or MajorTick

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