QwtSeriesStore 和 QwtPlotSeriesItem 之间的桥梁

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.
