Public Member Functions

 GraphicsLinesForCurve (const QString &curveName)
 Single constructor.
 
void addPoint (const QString &pointIdentifier, double ordinal, GraphicsPoint &point)
 Add new line. More...
 
double identifierToOrdinal (const QString &identifier) const
 Get ordinal for specified identifier.
 
void lineMembershipPurge (const LineStyle &lineStyle)
 Mark the end of addPoint calls. Remove stale lines, insert missing lines, and draw the graphics lines.
 
void lineMembershipReset ()
 Mark points as unwanted. Afterwards, lineMembershipPurge gets called.
 
void printStream (QString indentation, QTextStream &str) const
 Debugging method that supports print method of this class and printStream method of some other class(es)
 
void removePoint (double ordinal)
 Remove the specified point. The act of deleting it will automatically remove it from the GraphicsScene.
 
void removeTemporaryPointIfExists ()
 Remove temporary point if it exists. More...
 
void updateAfterCommand (GraphicsScene &scene, const PointStyle &pointStyle, const Point &point, GeometryWindow *geometryWindow)
 Update the GraphicsScene with the specified Point from the Document. If it does not exist yet in the scene, we add it.
 
void updateCurveStyle (const CurveStyle &curveStyle)
 Update the curve style for this curve.
 
void updateGraphicsLinesToMatchGraphicsPoints (const LineStyle &lineStyle)
 Calls to moveLinesWithDraggedPoint have finished so update the lines correspondingly.
 
void updateHighlightOpacity (double highlightOpacity)
 Update the highlight opacity value. This may or may not affect the current display immediately depending on the state.
 
void updatePointOrdinalsAfterDrag (const LineStyle &lineStyle, const Transformation &transformation)
 See GraphicsScene::updateOrdinalsAfterDrag. Pretty much the same steps as Curve::updatePointOrdinals.
 

Detailed Description

This class stores the GraphicsLine objects for one Curve.

The container is a QMap since that container maintains order by key

Member Function Documentation

◆ addPoint()

void GraphicsLinesForCurve::addPoint ( const QString &  pointIdentifier,
double  ordinal,
GraphicsPoint point 
)

Add new line.

The GraphicsPoint arguments are not const since this line binds to the points, so dragging points also drags the lines. The ordinal is already in the GraphicsPoint as DATA_KEY_ORDINAL

Definition at line 53 of file GraphicsLinesForCurve.cpp.

◆ removeTemporaryPointIfExists()

void GraphicsLinesForCurve::removeTemporaryPointIfExists ( )

Remove temporary point if it exists.

Temporary point handling is so complicated that this method quietly allows redundant calls to this method, without complaining that the point has already been removed when called again
