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()
