Member Typedef Documentation

◆ ConstSPtr

typedef QSharedPointer<const FilterPlotScene> DISPLIB::FilterPlotScene::ConstSPtr

Const shared pointer type for FilterPlotScene class.

Definition at line 85 of file filterplotscene.h.

◆ SPtr

typedef QSharedPointer<FilterPlotScene> DISPLIB::FilterPlotScene::SPtr

Constructor & Destructor Documentation

◆ FilterPlotScene()

FilterPlotScene::FilterPlotScene ( QGraphicsView * view,
QObject * parent = 0 )

Constructs a FilterPlotScene dialog which is a child of parent.

Parameters
[in]parentpointer to parent widget; If parent is 0, the new FilterPlotScene becomes a window. If parent is another widget, FilterPlotScene becomes a child window inside parent. FilterPlotScene is deleted when its parent is deleted.

Definition at line 66 of file filterplotscene.cpp.

Member Function Documentation

◆ plotFilterFrequencyResponse()

void FilterPlotScene::plotFilterFrequencyResponse ( )
protected

Plots the filter's frequency response.

Definition at line 220 of file filterplotscene.cpp.

◆ plotMagnitudeDiagram()

void FilterPlotScene::plotMagnitudeDiagram ( int samplingFreq,
const QString & filtername = QString() )
protected

Draws the diagram to plot the magnitude.

Parameters
[in]holdsthe current sampling frequency.
[in]holdsthe current name of the filter. Default is an empty QString.

Definition at line 114 of file filterplotscene.cpp.

◆ updateFilter()

void FilterPlotScene::updateFilter ( const RTPROCESSINGLIB::FilterKernel & operatorFilter,
int samplingFreq,
int cutOffLow,
int cutOffHigh )

Updates the current filter.

Parameters
[in]operatorFilterpointer to the current filter operator which is to be plotted.
[in]samplingFreqholds the current sampling frequency.
[in]cutOffLowcut off frequqency lowpass or lower cut off when filter is a bandpass.
[in]cutOffHighcut off frequqency highpass or higher cut off when filter is a bandpass.
