Groups and nodes

GoJS
#1

Hi walter,
i have a diagram of this model. sample link is below.

https://gojs.net/latest/samples/regrouping.html

how can i get outgoing nodes and groups from system_1 in above image?
how can i get incoming nodes and groups from system_2 in above image?
how can i get top level part for outgoing nodes and groups from system_1 in above image?
how can i get top level part for incoming nodes and groups from system_2 in above image?

I think you want to call Group.findExternalLinksConnected. Look at each Link to see whether its Link.fromNode’s Part.findTopLevelPart is the group you are starting from or not.

Does this answer your question?

#3

this will be ok. but in findExternalLinksConnected , i will get incoming and outgoing links. is there any direct way to get directly outgoinggroups and outgoingnodes like node.findNodesOutOf() ?

#4

No, that is why I suggested that you look at the findTopLevelPart of the Link.fromNode to see if the link is going out or not.
