cPolylineFigure Class Reference

#include <ccanvas.h>

Description

A figure that displays a line that consists of multiple connecting straight line segments or of a single smooth curve.

The class stores geometry information as a sequence of points. The line may be smoothed. A smoothed line is drawn as a series of Bezier curves, which touch the start point of the first line segment, the end point of the last line segment, and the midpoints of intermediate line segments, while intermediate points serve as control points. To add corners to a smoothed curve, duplicate points.

Additional properties such as color and line style are inherited from cAbstractLineFigure.

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 cAbstractLineFigure.

◆ dup()

virtual cPolylineFigure* 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 cAbstractLineFigure.

◆ str()

virtual std::string str ( ) const
overridevirtual

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

Reimplemented from cAbstractLineFigure.

◆ 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 cAbstractLineFigure.

◆ 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 e.g. 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.

◆ setNumPoints()

virtual void setNumPoints ( int  size)
virtual

Sets the number of points that define the polyline. (Appends new points or drops trailing points as needed.)

◆ 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 point 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 smoothed curve, and false if as a sequence of connecting of straight line segments. See the class description for details on how the points define the curve in the smoothed case.

◆ setSmooth()

virtual void setSmooth ( bool  smooth)
virtual

Sets the flag that determines whether connecting straight line segments or a single smooth curve should be drawn. See the class description for details on how the points define the curve in the smoothed case. The default value is false (no smoothing).

◆ 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.
