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.

成员函数说明

dataChanged()

virtual void QwtAbstractSeriesStore::dataChanged ( )

protectedpure virtual

dataChanged() indicates, that the series has been changed.

在 QwtPlotSeriesItem , 以及 QwtPlotVectorField 内被实现.

dataRect()

virtual QRectF QwtAbstractSeriesStore::dataRect ( ) const

protectedpure virtual

返回

Bounding rectangle of the stored series

在 QwtSeriesStore< T >, QwtSeriesStore< QPointF >, QwtSeriesStore< QwtBoxSample >, QwtSeriesStore< QwtIntervalSample >, QwtSeriesStore< QwtOHLCSample >, QwtSeriesStore< QwtPoint3D >, QwtSeriesStore< QwtSetSample > , 以及 QwtSeriesStore< QwtVectorFieldSample > 内被实现.

dataSize()

virtual size_t QwtAbstractSeriesStore::dataSize ( ) const

protectedpure virtual

返回

Number of samples

在 QwtSeriesStore< T >, QwtSeriesStore< QPointF >, QwtSeriesStore< QwtBoxSample >, QwtSeriesStore< QwtIntervalSample >, QwtSeriesStore< QwtOHLCSample >, QwtSeriesStore< QwtPoint3D >, QwtSeriesStore< QwtSetSample > , 以及 QwtSeriesStore< QwtVectorFieldSample > 内被实现.

setRectOfInterest()

virtual void QwtAbstractSeriesStore::setRectOfInterest ( const QRectF &  )

protectedpure virtual

Set a the "rectangle of interest" for the stored series

在 QwtSeriesStore< T >, QwtSeriesStore< QPointF >, QwtSeriesStore< QwtBoxSample >, QwtSeriesStore< QwtIntervalSample >, QwtSeriesStore< QwtOHLCSample >, QwtSeriesStore< QwtPoint3D >, QwtSeriesStore< QwtSetSample > , 以及 QwtSeriesStore< QwtVectorFieldSample > 内被实现.
