ManhattanConnectionRouter revisited [message #8422]

OK, I guess I'm just too dumb (lazy?) to see through the obtuse hierarchy of
classes in the logic demo - I just can't figure out how to implement a
ManhattanConnectionRouter. Can someone please explain to this simpleton
(i.e. me) how to do this? Thanks in advance...

I'm not really sure what you're having trouble with. Could you be more
specific?

Bob,

there's nothing to implement, you can use the class as is.

just
- create two figures
- create an anchor per figure (eg ChopboxAnchor) and refer to the
figure in the anchor's constructor
- create an connection (Polyline..)
- set the connections start and end anchor
- set a router (i.e. ManhattanConnectionRouter) for the connection
- invoke route() on the connection

the router will then:
- erase the pointlist of the connection
- let the anchors calculate their resp. positions (for a chopbox this
is determined by the intersection of the line going through the centers
of the enclosing rectangles of both figures and those rectangles
themselves )
- add a start and end point to the pointlist of the connection
corresponding with the positions of the anchors
- add points between those begin and end point specific to the router's
algorithm. For a manhattan algorithm the connection will have only
vertical and /or horizontal strokes.

You don't need to invoke route(). route is part of validate(), which gets
called automatically.

Hi!

The ManhattenRouter is great, but it is possible to modify it a little bit
for 2.0 release?
Look at the attached picture. I added a arrow decoration to the end of the
target connection. The ManhattenRouter routes after its strict algorithm. I
think it should look at decorations (especially arrows) to ensure a better
quality of routing, which looks nicer.

Please open a feature request. There is nothing on the decoration that
would tell us how "big" it is. Maybe you could just configure the router
with an offset.
