cPathFigure Class Reference

#include <ccanvas.h>

Description

A figure that displays a "path", a complex shape or line modeled after SVG paths.

A path is may consist of any number of straight line segments, Bezier curves and arcs. The path can be disjoint as well. Closed paths may be filled. 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.

The path may be specified with a string similar to an SVG path, or assembled by calling methods that append new segments (straight lines, arcs or Bezier curves) to the existing path.

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 cPathFigure* 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

The move operation modifies the offset field (see getOffset()).

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.

◆ 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.

◆ getCapStyle()

virtual CapStyle getCapStyle ( ) const
inlinevirtual

Returns the cap style for the figure's line.

◆ setCapStyle()

virtual void setCapStyle ( CapStyle  capStyle)
virtual

Sets the cap style for the figure's line. The default cap style is butt.

◆ getFillRule()

virtual FillRule getFillRule ( ) const
inlinevirtual

Returns the fill rule of the path. This attribute is only important with closed, filled, self-intersecting paths (and those that contain such parts). 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 path. This attribute is only important with closed, filled, self-intersecting paths (and those that contain such parts). The interpretation of the fill rule is consistent with its SVG definition.

The default fill rule is evenodd.

◆ getOffset()

virtual const Point& getOffset ( ) const
inlinevirtual

Returns the coordinate offset of the path. A nonzero offset causes the path to appear translated by the given amount in the local coordinate system.

◆ setOffset()

virtual void setOffset ( const Point offset)
virtual

Sets the coordinate offset of the path. Setting a nonzero offset causes the path to appear translated by the given amount in the local coordinate system. The elements of the path remain unchanged. This method primarily exists so that moveLocal() can be a constant-time operation.

◆ getPath()

virtual const char* getPath ( ) const
virtual

Returns the path as a string.

◆ setPath()

virtual void setPath ( const char *  path)
virtual

Sets the path from a string. It will be parsed, made available via the getNumPathItems(), getPathItem() methods, and may be further modified with the "add" methods.

◆ getNumPathItems()

virtual int getNumPathItems ( ) const
inlinevirtual

Returns the number of path items.

◆ getPathItem()

virtual const PathItem* getPathItem ( int  k) const
inlinevirtual

Returns the kth path item. The returned item may be cast to the appropriate subtype (MoveTo, MoveRel, etc.) after examining its code field.

◆ clearPath()

virtual void clearPath ( )
virtual

Clears the path by discarding its path items.

◆ addMoveTo()

virtual void addMoveTo ( double  x,
double  y 
)
virtual

Appends a MoveTo item to the path. It will move the "pen" to (x,y), and begin a new subpath. Paths should begin with a MoveTo.

SVG equivalent: "M <x> <y>"

◆ addMoveRel()

virtual void addMoveRel ( double  dx,
double  dy 
)
virtual

Appends a MoveRel item to the path. It will move the "pen" from the current point (lastx,lasty) to (lastx+dx,lasty+dy), and begin a new subpath.

SVG equivalent: "m <dx> <dy>"

◆ addLineTo()

virtual void addLineTo ( double  x,
double  y 
)
virtual

Appends a LineTo item to the path. It will draw a line from the last point to (x,y).

SVG equivalent: "L <x> <y>"

◆ addLineRel()

virtual void addLineRel ( double  dx,
double  dy 
)
virtual

Appends a LineRel item to the path. It will draw a line from the current point (lastx, lasty) to (lastx+dx, lasty+dy).

SVG equivalent: "l <dx> <dy>"

◆ addHorizontalLineTo()

virtual void addHorizontalLineTo ( double  x)
virtual

Appends a HorizontalLineTo item to the path. It will draw a line from the current point (lastx, lasty) to (x, lasty).

SVG equivalent: "H <x>"

◆ addHorizontalLineRel()

virtual void addHorizontalLineRel ( double  dx)
virtual

Appends a HorizontalLineRel item to the path. It will draw a line from the current point (lastx, lasty) to (lastx+dx, lasty).

SVG equivalent: "h <dx>"

◆ addVerticalLineTo()

virtual void addVerticalLineTo ( double  y)
virtual

Appends a VerticalLineTo item to the path. It will draw a line from the current point (lastx, lasty) to the (lastx, y) point.

SVG equivalent: "V <y>"

◆ addVerticalLineRel()

virtual void addVerticalLineRel ( double  dy)
virtual

Appends a VerticalLineRel item to the path. It will draw a line from the current point (lastx, lasty) to (lastx, lasty+dy).

SVG equivalent: "v <dy>"

◆ addArcTo()

virtual void addArcTo ( double  rx,
double  ry,
double  phi,
bool  largeArc,
bool  sweep,
double  x,
double  y 
)
virtual

Appends an ArcTo item to the path. It will draw an arc from the last point to the (x,y) point. The size and orientation of the ellipse are defined by two radii (rx, ry) and a phi rotation angle. The center of the ellipse is calculated automatically to satisfy the constraints imposed by the other parameters. The largeArc and sweep flags determine which of the four possible arcs are chosen. If largeArc=true, then one of the larger (greater than 180 degrees) arcs are chosen, otherwise one of the the smaller ones. If sweep=true, the arc will be drawn in the "positive-angle" direction, otherwise in the negative-angle direction.

SVG equivalent: "A <rx> <ry> <phi> <largeArc> <sweep> <x> <y>"

◆ addArcRel()

virtual void addArcRel ( double  rx,
double  ry,
double  phi,
bool  largeArc,
bool  sweep,
double  dx,
double  dy 
)
virtual

Appends an ArcRel item to the path. It will draw an arc from the last point (lastx, lasty) to (lastx+dx, lasty+dy). Just as with addArcTo(), the size and orientation of the ellipse are defined by two radii (rx, ry) and a phi rotation angle. The center of the ellipse is calculated automatically to satisfy the constraints imposed by the other parameters. The largeArc and sweep flags determine which of the four possible arcs are chosen. If largeArc=true, then one of the larger (greater than 180 degrees) arcs are chosen, otherwise one of the the smaller ones. If sweep=true, the arc will be drawn in the "positive-angle" direction, otherwise in the negative-angle direction.

SVG equivalent: "a <rx> <ry> <phi> <largeArc> <sweep> <dx> <dy>"

◆ addCurveTo()

virtual void addCurveTo ( double  x1,
double  y1,
double  x,
double  y 
)
virtual

SVG equivalent: "Q <x1> <y1> <x> <y>"

◆ addCurveRel()

virtual void addCurveRel ( double  dx1,
double  dy1,
double  dx,
double  dy 
)
virtual

Appends a CurveRel item to the path. It will draw a quadratic Bezier curve from the current point (lastx, lasty) to (lastx+dx, lasty+dy) using (lastx+dx1, lasty+dy1) as the control point.

◆ addSmoothCurveTo()

virtual void addSmoothCurveTo ( double  x,
double  y 
)
virtual

The control point is assumed to be the reflection of the control point on the previous command relative to the current point. (If there is no previous command or if the previous command was not a quadratic Bezier curve command such as Q, q, T or t, assume the control point is coincident with the current point.)

SVG equivalent: "T <x> <y>"

◆ addSmoothCurveRel()

virtual void addSmoothCurveRel ( double  dx,
double  dy 
)
virtual

Appends a SmoothCurveRel item to the path. It will draw a quadratic Bezier curve from the current point (lastx, lasty) to (last+dx, lasty+dy). The control point is assumed to be the reflection of the control point on the previous command relative to the current point. (If there is no previous command or if the previous command was not a quadratic Bezier curve command such as Q, q, T or t, assume the control point is coincident with the current point.)

SVG equivalent: "t <dx> <dy>"

◆ addCubicBezierCurveTo()

virtual void addCubicBezierCurveTo ( double  x1,
double  y1,
double  x2,
double  y2,
double  x,
double  y 
)
virtual

Appends a CubicBezierCurveTo item to the path. It will draw a cubic Bezier curve from the current point to (x,y) using (x1,y1) as the control point at the beginning of the curve and (x2,y2) as the control point at the end of the curve.

SVG equivalent: "C <x1> <y1> <x2> <y2> <x> <y>"

◆ addCubicBezierCurveRel()

virtual void addCubicBezierCurveRel ( double  dx1,
double  dy1,
double  dx2,
double  dy2,
double  dx,
double  dy 
)
virtual

SVG equivalent: "c <dx1> <dy1> <dx2> <dy2> <dx> <dy>"

◆ addSmoothCubicBezierCurveTo()

virtual void addSmoothCubicBezierCurveTo ( double  x2,
double  y2,
double  x,
double  y 
)
virtual

Appends a SmoothCubicBezierCurveTo item to the path. It will draw a cubic Bezier curve from the current point to (x,y). The first control point is assumed to be the reflection of the second control point on the previous command relative to the last point. (If there is no previous command or if the previous command was not a cubic Bezier command such as C, c, S or s, assume the first control point is coincident with the current point.) (x2,y2) is the second control point (i.e., the control point at the end of the curve).

SVG equivalent: "S <x2> <y2> <x> <y>"

◆ addSmoothCubicBezierCurveRel()

virtual void addSmoothCubicBezierCurveRel ( double  dx2,
double  dy2,
double  dx,
double  dy 
)
virtual

Appends a SmoothCubicBezierCurveRel item to the path. It will draw a cubic Bezier curve from the current point (lastx, lasty) to (lastx+dx, lasty+dy). The first control point is assumed to be the reflection of the second control point on the previous command relative to the last point. (If there is no previous command or if the previous command was not a cubic Bezier command such as C, c, S or s, assume the first control point is coincident with the current point.)
