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.

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 ( double  lowerBound,
double  upperBound,
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 ( double  value  )  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 (  )

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]
void QwtScaleDiv::setInterval ( const QwtInterval interval  ) 

Change the interval

Parameters:
interval Interval
void QwtScaleDiv::setInterval ( double  lowerBound,
double  upperBound 
) [inline]

upperBound upper bound
void QwtScaleDiv::setTicks ( int  type,
const QList< double > &  ticks 
)

Assign ticks

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

Return a list of ticks

Parameters:
type MinorTick, MediumTick or MajorTick
