BackgroundStateCurve(BackgroundStateContext &context, GraphicsScene &scene)
Single constructor.
virtual void setCurveSelected(bool isGnuplot, const Transformation &transformation, const DocumentModelGridRemoval &modelGridRemoval, const DocumentModelColorFilter &colorFilter, const QString &curveSelected)
Update the currently selected curve name.
virtual void setPixmap(bool isGnuplot, const Transformation &transformation, const DocumentModelGridRemoval &modelGridRemoval, const DocumentModelColorFilter &modelColorFilter, const QPixmap &pixmapOriginal, const QString &curveSelected)
Update the image for this state, after the leaf class processes it appropriately.
virtual void fitInView(GraphicsView &view)
Zoom so background fills the window.
