Change Link Style programatically

[William McKenzie]

How does one change the Line Style of a connector using the automation interface? For instance, I would like to walk through my diagram and change all of the links to 'Direct' routing (the equivalent of Ctrl+Shift+D). It seems like there are several possible related properties (like Style, Path,  & Geometry), but there is no clear documentation on how to use these properties to select a particular element to element routing style.

OK, I did a little dump of those properties, and this is what I get:

Path:
624:-1024;      

Geometry:
SX=0;SY=0;EX=0;EY=0;EDGE=1;$LLB=;LLT=;LMT=;LMB=CX=164:CY=14:OX=0:OY=0:HDN=0:BLD=0:ITA=0:UND=0:CLR=-1:ALN=0:DIR=0:ROT=0;LRT=;LRB=;IRHS=;ILHS=;      

Style:
Mode=3;EOID=00ADA3AA;SOID=59EEEB46;Color=-1;LWidth=0;TREE=OR;      

Maybe it's the 'Mode' part of the style? In which case, does someone know the enumeration for those values?

Hi William,

It might indeed have something to do with the mode, and maybe also with the TREE=OR part.
Figuring this out shouldn't be too hard should it?
Just make a link in each style and inspect the t_diagramlinks table.

Searching this forum for "link style" also shows some interesting posts.

And even more interesting: an open source add-in that changes the link styles:

Line Stye: TREE=OR; means orthogonal rounded; OS = Ort. square and so on.

Thanks, all. Those hints will get me going.
