Update the images of all states, rather than just the current state.
void updateColorFilter(const Transformation &transformation, const DocumentModelGridRemoval &modelGridRemoval, const DocumentModelColorFilter &colorFilter, const QString &curveSelected)
Apply color filter settings.
void fitInView(GraphicsView &view)
Zoom so background fills the window.
void requestStateTransition(BackgroundState backgroundState)
Initiate state transition to be performed later, when BackgroundState is off the stack.
void setBackgroundImage(BackgroundImage backgroundImage)
Transition to the specified state. This method is used by classes outside of the state machine to tri...

void close()
Open Document is being closed so remove the background.
void setCurveSelected(const Transformation &transformation, const DocumentModelGridRemoval &modelGridRemoval, const DocumentModelColorFilter &modelColorFilter, const QString &curveSelected)
Update the selected curve.
