- public class FigEdgeRectiline
- extends FigEdge
A Fig that paints edges between ports. This version
automatically routes a rectilinear edge. The routing is not very
good. It avoids the source and sink nodes and no other nodes. It is
basically case-analysis, and some of the cases are wrong or
missing. Anyway, the user can edit the edge by dragging
handles. The 0th and last handles are fixed in position so that
they stay connected to ports. If the user drags a handle next to a
fixed handle, a new vertex is automatically inserted.

_initiallyLaidOut
protected boolean _initiallyLaidOut
- True if the edge has been laid out automatically once. It will
not be done automatically again since the user may have edited the
edge and I dont want to undo that work.
FigEdgeRectiline
public FigEdgeRectiline()
makeEdgeFig
protected Fig makeEdgeFig()
- Instanciate a FigPoly with its rectilinear flag set. By default
the FigPoly is black and the FigEdge has now ArrowHeads.
- Overrides:
- makeEdgeFig in class FigEdge
computeRoute
protected void computeRoute()
- Find the route that the edge should follow. Basically case
analysis to route around source and destination nodes.
Needs-More-Work: A better algorithm would really be useful.
Needs-More-Work: Sometimes the edge can get non-rectilinear.
- Overrides:
- computeRoute in class FigEdge
layoutEdge
protected void layoutEdge()
- Internal function to actually compute the layout of the line if
it has never been done on that line before.
routingRectPoint
protected Point routingRectPoint(Point p,
Rectangle r,
int sector)
- Reply a point on the given routing rect that is "straight out"
from the connection point in the proper direction.
tryRoute
protected int tryRoute(int x,
int y,
int np,
int[] xs,
int[] ys,
Rectangle avoid1,
Rectangle avoid2,
int srcSector,
int dstSector)
- Try to find a route from the last point in (xs, ys) to point (x,
y). Try to avoid the given rectangles along the
way. Needs-More-Work: should allow a vector of rectangles to
avoid.
findAvoidPt
protected Point findAvoidPt(int fx,
int fy,
int x,
int y,
Rectangle avoid1,
Rectangle avoid2)
- Find a point on the corner of one of the avoid rectangles that
is a good intermediate point for the edge layout.
segOK
protected boolean segOK(int x1,
int y1,
int x2,
int y2,
Rectangle avoid1,
Rectangle avoid2)
- Reply true if the line segment from (x1, y1) to (x2, y2) does
not intersect the given avoid rectangles.
