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> const QwtSeriesData< T > * QwtSeriesStore< T >::data() const [inline]

Returns

the the series data

Definition at line 152 of file qwt_series_store.h.

template<typename T> QRectF QwtSeriesStore< T >::dataRect () const[override], [virtual]

Returns

Bounding rectangle of the series or an invalid rectangle, when no series is stored

See also

QwtSeriesData<T>::boundingRect()

Implements QwtAbstractSeriesStore.

Definition at line 184 of file qwt_series_store.h.

template<typename T> size_t QwtSeriesStore< T >::dataSize () const[override], [virtual]

Returns

Number of samples of the series

See also

setData(), QwtSeriesData<T>::size()

Implements QwtAbstractSeriesStore.

Definition at line 175 of file qwt_series_store.h.

template<typename T> T QwtSeriesStore< T >::sample (int index) const[inline]

Parameters

index Index

Returns

Sample at position index

template<typename T> void QwtSeriesStore< T >::setData (QwtSeriesData< T >* series)

Assign a series of samples

Parameters

series Data

Warning

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

Set a the "rect of interest" for the series

Parameters

rect Rectangle of interest

Definition at line 193 of file qwt_series_store.h.

template<typename T> QwtSeriesData< T > * QwtSeriesStore< T >::swapData(QwtSeriesData< T > * series)

Replace a series without deleting the previous one

Parameters

series New series

Returns

Previously assigned series
