Hi,

I am using Manhattan Connection to connect between two Shapes. When I am trying to create connection with Polygon, not able to connect at Polygon points. How to add my connection only at Polygon points.

I am using gaService.createPolyLine(gaContainer) for polyline in Connection

Anil,

nut sure if I got that question ...

As I understood you want to have your connections start and end only at
polygon points of your shapes. You can achieve that by defining
BoxRelativeAnchors or FixPointAnchors for your shape that are located at the
same places as the polygon points. On creation of the connection you change
the anchor passed in the context to one of these anchors.

By default shapes get a ChopboxAnchor that is located in the middle of the
shape, so all connections will point there (rendering is clipped at the edge
of the shape).

See
http://help.eclipse.org/kepler/index.jsp?topic=%2Forg.eclipse.graphiti.doc%2Fresources%2Fdocu%2Fgfw%2Fanchors.htm&cp=27_1_3_8_1
for details on Anchors.

Michael
