Constructor Detail

FigArrow

public FigArrow()

FigArrow

public FigArrow(FigObject parent,
                java.awt.Point p1,
                java.awt.Point p2,
                boolean front)

construct an arrow of type parent.getAttributes().arrowMode for the line from point p1 to point p2 (with coordinates in world coordinates. As FIG3.1 allows different arrowheads on the front or back end of a polyline, the flag 'front' is used to select the corresponding end. 01.02.97: changed width -> 0.5*width to get xfig/transfig semantic

Method Detail

create

public static FigArrow create(FigObject parent,
                              java.awt.Point p1,
                              java.awt.Point p2,
                              boolean front)

paint

public void paint(java.awt.Graphics g)

the paint method for an arrow. This checks whether to draw a solderdot arrow and does so. Otherwise the paint() method for the previously created LineWrapper and FillWrapper objects is called.

toString

public java.lang.String toString()

print

public void print()
