Detailed Description

A legend item for polar plots.

Warning: In this QCustomPlot version, polar plots are a tech preview. Expect documentation and functionality to be incomplete, as well as changing public interfaces in the future.

Member Function Documentation

§ draw()

void QCPPolarLegendItem::draw ( QCPPainter * painter )

protectedvirtual

This function draws the layerable with the specified painter. It is only called by QCustomPlot, if the layerable is visible (setVisible).

Before this function is called, the painter's antialiasing state is set via applyDefaultAntialiasingHint, see the documentation there. Further, the clipping rectangle was set to clipRect.

Implements QCPAbstractLegendItem.

§ minimumOuterSizeHint()

QSize QCPPolarLegendItem::minimumOuterSizeHint ( ) const

protectedvirtual

Returns the suggested minimum size this layout element (the outerRect) may be compressed to, if no manual minimum size is set.

if a minimum size (setMinimumSize) was not set manually, parent layouts use the returned size (usually indirectly through QCPLayout::getFinalMinimumOuterSize) to determine the minimum allowed size of this layout element.

A manual minimum size is considered set if it is non-zero.

The default implementation simply returns the sum of the horizontal margins for the width and the sum of the vertical margins for the height. Reimplementations may use their detailed knowledge about the layout element's content to provide size hints.

Reimplemented from QCPLayoutElement.
