Description

A figure that displays a (closed) polygon, determined by a sequence of points.

The polygon may be smoothed. A smoothed polygon is drawn as a series of cubic Bezier curves, where the curves touch the midpoints of the sides, and vertices serve as control points. As with all shape figures, drawing of both the outline and the fill are optional. The drawing of filled self- intersecting polygons is controlled by the fill rule property. Line and fill color, and several other properties are inherited from cAbstractShapeFigure.

Member Function Documentation

◆ getAllowedPropertyKeys()

virtual const char** getAllowedPropertyKeys ( ) const

overrideprotectedvirtual

Returns the list of allowed keys in @figure properties with this figure type, in a nullptr-terminated array of const char* elements. This method is invoked e.g. from parse(), in order to be able to issue error messages for invalid keys in the property. Note that property keys starting with "x-" are already allowed by default. Custom figure classes usually need to override this method together with parse(); see the source code of the library classes for example implementations.

Reimplemented from cAbstractShapeFigure.

◆ dup()

virtual cPolygonFigure* dup ( ) const

inlineoverridevirtual

Clones the figure, ignoring its child figures. (The copy will have no children.) To clone a figure together with its figure subtree, use dupTree().

Reimplemented from cAbstractShapeFigure.

◆ str()

virtual std::string str ( ) const

overridevirtual

Returns a one-line string with the most characteristic data of the figure.

Reimplemented from cAbstractShapeFigure.

◆ parse()

virtual void parse ( cProperty * property )

overridevirtual

This method is invoked by the simulation library to initialize the figure from a @figure NED property. Custom figure classes usually need to override this method (and call the super class' similar method in it).

Note: When overriding parse(), it is usually also necessary to override getAllowedPropertyKeys(), in order to allow new keys in the @figure property.

Reimplemented from cAbstractShapeFigure.

◆ moveLocal()

virtual void moveLocal	(	double	dx,
		double	dy
	)

overridevirtual

Change the figure's position by the given x and y deltas. Child figures will not be affected.

Implements cFigure.

◆ getRendererClassName()

virtual const char* getRendererClassName ( ) const

inlineoverridevirtual

Returns the name of the class responsible for rendering this figure. Renderer classes are specific to, and are usually implemented as part of, the graphical user interface library (Tkenv or Qtenv).

Implements cFigure.

◆ getPoints()

virtual const std::vector<Point>& getPoints ( ) const

inlinevirtual

Returns the points that define the polyline.

◆ setPoints()

virtual void setPoints ( const std::vector< Point > & points )

virtual

Sets the points that define the polyline.

◆ getNumPoints()

virtual int getNumPoints ( ) const

inlinevirtual

Returns the number of points. Equivalent to getPoints().size().

◆ getPoint()

virtual const Point& getPoint ( int i ) const

inlinevirtual

Returns the ith point. The index must be in the 0..getNumPoints()-1 interval.

◆ setPoint()

virtual void setPoint	(	int	i,
		const Point &	point
	)

virtual

Sets the ith point. The index must be in the 0..getNumPoints()-1 interval.

◆ addPoint()

virtual void addPoint ( const Point & point )

virtual

Appends a point.

◆ removePoint()

virtual void removePoint ( int i )

virtual

Removes the ith point. The index must be in the 0..getNumPoints()-1 interval.

◆ insertPoint()

virtual void insertPoint	(	int	i,
		const Point &	point
	)

virtual

Inserts a point at position i, shifting up the points at and above index i. The index must be in the 0..getNumPoints()-1 interval.

◆ getSmooth()

virtual bool getSmooth ( ) const

inlinevirtual

Returns true if the figure is rendered as a closed smooth curve, and false if as a polygon. See the class description for details.

◆ setSmooth()

virtual void setSmooth ( bool smooth )

virtual

Sets the flag that determines whether a polygon or a smooth closed curve should be drawn. See the class description for details on how the points define the curve in the smoothed case.

◆ getJoinStyle()

virtual JoinStyle getJoinStyle ( ) const

inlinevirtual

Returns the join style line segments will be connected with.

◆ setJoinStyle()

virtual void setJoinStyle ( JoinStyle joinStyle )

virtual

Sets the join style line segments will be connected with. The default join style is miter.

◆ getFillRule()

virtual FillRule getFillRule ( ) const

inlinevirtual

Returns the fill rule of the polygon. This attribute is only important with filled, self-intersecting polygons. The interpretation of the fill rule is consistent with its SVG definition.

◆ setFillRule()

virtual void setFillRule ( FillRule fillRule )

virtual

Sets the fill rule of the polygon. This attribute is only important with filled, self-intersecting polygons. The interpretation of the fill rule is consistent with its SVG definition.

The default fill rule is evenodd.
