Constructor & Destructor Documentation

◆ KDChartRingPainter()

KDChartRingPainter::KDChartRingPainter ( KDChartParams * params)
protected

Constructor.

Sets up internal data structures as necessary.

Parameters
paramsthe KDChartParams structure that defines the chart

Definition at line 52 of file KDChartRingPainter.cpp.

◆ ~KDChartRingPainter()

KDChartRingPainter::~KDChartRingPainter ( )
protectedvirtual

Destructor.

Definition at line 63 of file KDChartRingPainter.cpp.

Member Function Documentation

◆ drawOneSegment()

void KDChartRingPainter::drawOneSegment ( TQPainter * painter,
uint outerRadius,
uint innerRadius,
double startAngle,
double angles,
uint dataset,
uint value,
uint chart,
bool explode,
KDChartDataRegionList * regions = 0 )
protected

Definition at line 217 of file KDChartRingPainter.cpp.

◆ fallbackLegendText()

TQString KDChartRingPainter::fallbackLegendText ( uint dataset) const
protectedvirtual

This method is a specialization that returns a fallback legend text appropriate for rings where the fallbacks should come from the values, not from the datasets.

This method is only used when automatic legends are used, because manual and first-column legends do not need fallback texts.

Parameters
uintdataset the dataset number for which to generate a fallback text
Returns
the fallback text to use for describing the specified dataset in the legend

Reimplemented from KDChartPainter.

Definition at line 376 of file KDChartRingPainter.cpp.

◆ numLegendFallbackTexts()

uint KDChartRingPainter::numLegendFallbackTexts ( KDChartTableDataBase * data) const
protectedvirtual

This methods returns the number of elements to be shown in the legend in case fallback texts are used.

This method is only used when automatic legends are used, because manual and first-column legends do not need fallback texts.

Returns
the number of fallback texts to use

Reimplemented from KDChartPainter.

Definition at line 391 of file KDChartRingPainter.cpp.

◆ paintData()

void KDChartRingPainter::paintData ( TQPainter * painter,
KDChartTableDataBase * data,
bool paint2nd,
KDChartDataRegionList * regions = 0 )
protectedvirtual

Paints the actual data area.

Parameters
painterthe TQPainter onto which the chart should be painted
datathe data that will be displayed as a chart
paint2ndspecifies whether the main chart or the additional chart is to be drawn now
regionsa pointer to a list of regions that will be filled with regions representing the data segments, if not null

Implements KDChartPainter.
