Detailed Description

template<typename T>
class QwtSeriesStore< T >

Class storing a QwtSeriesData object.

QwtSeriesStore and QwtPlotSeriesItem are intended as base classes for all plot items iterating over a series of samples. Both classes share a virtual base class ( QwtAbstractSeriesStore ) to bridge between them.

QwtSeriesStore offers the template based part for the plot item API, so that QwtPlotSeriesItem can be derived without any hassle with templates.

template<typename T >
QwtSeriesData< T > * QwtSeriesStore< T >::data ( ) [inline]
Returns:
the the series data
template<typename T >

Implements QwtAbstractSeriesStore.

template<typename T >
size_t QwtSeriesStore< T >::dataSize ( ) const [virtual]
Returns:
Number of samples of the series
See also:
setData(), QwtSeriesData<T>::size()

Implements QwtAbstractSeriesStore.

template<typename T >
T QwtSeriesStore< T >::sample ( int  index) const [inline]
Parameters:
indexIndex
Returns:
Sample at position index
template<typename T>
void QwtSeriesStore< T >::setData ( QwtSeriesData< T > *  series)

Assign a series of samples

Parameters:
seriesData
Warning:
The item takes ownership of the data object, deleting it when its not used anymore.

Parameters:
rectRectangle of interest
See also:

Parameters:
seriesNew series
Returns:
Previously assigned series
