Public Member Functions

 Point ()
 Default constructor so this class can be used inside a container.
 
 Point (const QString &curveName, const QPointF &posScreen)
 Constructor for Checker temporary points, before real point gets added. More...
 
 Point (const QString &curveName, const QPointF &posScreen, const QPointF &posGraph, bool isXOnly)
 Constructor for temporary point used to pre-check transformation points, before real point gets added. More...
 
 Point (const QString &curveName, const QString &identifier, const QPointF &posScreen, const QPointF &posGraph, double ordinal, bool isXOnly)
 Constructor for axis points with identifier (after redo). The position, in screen coordinates, applies to the center of the Point.
 
 Point (const QString &curveName, const QPointF &posScreen, const QPointF &posGraph, double ordinal, bool isXOnly)
 Constructor for axis points without identifier (after redo). The position, in screen coordinates, applies to the center of the Point.
 
 Point (const QString &curveName, const QString &identifier, const QPointF &posScreen, double ordinal)
 Constructor for graph points with identifier (after redo)
 
 Point (const QString &curveName, const QPointF &posScreen, double ordinal)
 Constructor for graph points without identifier (after redo)
 
 Point (QXmlStreamReader &reader)
 Constructor when loading from serialized xml.
 
Pointoperator= (const Point &point)
 Assignment constructor.
 
 Point (const Point &point)
 Copy constructor.
 
bool hasOrdinal () const
 True if ordinal is defined.
 
bool hasPosGraph () const
 True if graph position is defined.
 
QString identifier () const
 Unique identifier for a specific Point.
 
bool isXOnly () const
 In DOCUMENT_AXES_POINTS_REQUIRED_4 modes, this is true/false if y/x coordinate is undefined.
 
bool isAxisPoint () const
 True if point is an axis point. This is used only for sanity checks.
 
double ordinal (ApplyHasCheck applyHasCheck=KEEP_HAS_CHECK) const
 Get method for ordinal. Skip check if copying one instance to another.
 
QPointF posGraph (ApplyHasCheck applyHasCheck=KEEP_HAS_CHECK) const
 Accessor for graph position. Skip check if copying one instance to another.
 
QPointF posScreen () const
 Accessor for screen position.
 
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 saveXml (QXmlStreamWriter &writer) const
 Serialize to stream.
 
void setCurveName (const QString &curveName)
 Update the point identifer to match the specified curve name.
 
void setOrdinal (double ordinal)
 Set the ordinal used for ordering Points.
 
void setPosGraph (const QPointF &posGraph)
 Set method for position in graph coordinates.
 
void setPosScreen (const QPointF &posScreen)
 Set method for position in screen coordinates.
 

Static Public Member Functions

static QString curveNameFromPointIdentifier (const QString &pointIdentifier)
 Parse the curve name from the specified point identifier. This does the opposite of uniqueIdentifierGenerator.
 
static unsigned int identifierIndex ()
 Return the current index for storage in case we need to reset it later while performing a Redo.
 
static void setIdentifierIndex (unsigned int identifierIndex)
 Reset the current index while performing a Redo.
 
static QString temporaryPointIdentifier ()
 Point identifier for temporary point that is used by DigitzeStateAxis.
 
static double UNDEFINED_ORDINAL ()
 Get method for undefined ordinal constant.
