BackgroundStateContext(MainWindow &mainWindow)
Single constructor.
void setPixmap(bool isGnuplot, const Transformation &transformation, const DocumentModelGridRemoval &modelGridRemoval, const DocumentModelColorFilter &modelColorFilter, const QPixmap &pixmapOriginal, const QString &curveSelected)
Update the images of all states, rather than just the current state.
void setBackgroundImage(BackgroundImage backgroundImage)
Transition to the specified state. This method is used by classes outside of the state machine to tri...
QImage imageForCurveState() const
Image for the Curve state, even if the current state is different.
void fitInView(GraphicsView &view)
Zoom so background fills the window.
void updateColorFilter(bool isGnuplot, const Transformation &transformation, const DocumentModelGridRemoval &modelGridRemoval, const DocumentModelColorFilter &colorFilter, const QString &curveSelected)
Apply color filter settings.
void close()
Open Document is being closed so remove the background.
void requestStateTransition(BackgroundState backgroundState)
Initiate state transition to be performed later, when BackgroundState is off the stack.
~BackgroundStateContext()
Destructor deallocates memory.
void setCurveSelected(bool isGnuplot, const Transformation &transformation, const DocumentModelGridRemoval &modelGridRemoval, const DocumentModelColorFilter &modelColorFilter, const QString &curveSelected)
Update the selected curve.
Background image state for showing filter image from current curve.
Background image state for showing no image.
Background image state for showing original (=unfiltered) image.
Background image state for interval between startup and loading of the image.
Model for DlgSettingsColorFilter and CmdSettingsColorFilter.
Model for DlgSettingsGridRemoval and CmdSettingsGridRemoval.
