Constructor & Destructor Documentation

QCPLabelPainterPrivate()

QCPLabelPainterPrivate::QCPLabelPainterPrivate ( QCustomPlot * parentPlot )

explicit

Constructs a QCPLabelPainterPrivate instance. Make sure to not create a new instance on every redraw, to utilize the caching mechanisms.

the parentPlot does not take ownership of the label painter. Make sure to delete it appropriately.
