I’m programming business process modeler with godiagram.
I have got some problem dealing with some situation.
I inherited GoIconicNode to implement 8-Port Icon Node with noresizable attribute.
the problem is I couldn’t draw backward link , when I select a node(source) to make a link to a certain node(destination) in modeler, I couldn’t find the focus over a node. A node without any link, I can connect to it. but If already with 1 more link. I couldn’t connect to them.
also What I found is that I think that in GoIconicNode, this node seems to consider precedence of nodes conneted, so I could connect to a forward node with several links, but I couldn’t connect to a backward node with even single link. is this true?
Is there any way to implement better with sample code?
What I want is, a port could be connected from several nodes and to serveral nodes, and a node has 8-port or more ports. In addition, I want to show highlist while connectiong two nodes on the ports of a node which is hovered by mouse.
Is there any one who can help me to solve this problem with sample code or how to do?
PS. I can draw the straight flow.
sample images are attached.
