# QwtAbstractSeriesStore(3)

Bridge between QwtSeriesStore and QwtPlotSeriesItem.

## NAME

QwtAbstractSeriesStore - Bridge between **QwtSeriesStore** and **QwtPlotSeriesItem**.

## SYNOPSIS

`#include <qwt_series_store.h>`

Inherited by **QwtPlotSeriesItem**` [virtual]`, **QwtSeriesStore\< T \>**` [virtual]`, **QwtSeriesStore\< QPointF \>**` [virtual]`, **QwtSeriesStore\< QwtIntervalSample \>**` [virtual]`, **QwtSeriesStore\< QwtOHLCSample \>**` [virtual]`, **QwtSeriesStore\< QwtPoint3D \>**` [virtual]`, and **QwtSeriesStore\< QwtSetSample \>**` [virtual]`.

### Protected Member Functions

virtual **~QwtAbstractSeriesStore** ()\
 Destructor.  virtual void **dataChanged** ()=0\
 **dataChanged()** indicates, that the series has been changed.  virtual void **setRectOfInterest** (const QRectF &)=0\
 virtual QRectF **dataRect** () const =0\
 virtual size\_t **dataSize** () const =0\

## Detailed Description

Bridge between **QwtSeriesStore** and **QwtPlotSeriesItem**.

**QwtAbstractSeriesStore** is an abstract interface only to make it possible to isolate the template based methods ( **QwtSeriesStore** ) from the regular methods ( **QwtPlotSeriesItem** ) to make it possible to derive from **QwtPlotSeriesItem** without any hassle with templates.

## Member Function Documentation

### virtual QRectF QwtAbstractSeriesStore::dataRect () const` [protected]`, ` [pure virtual]`
