As per my requirement i have multiple group containing nested sub groups and their nodes . Now i want to get all nodes of any group by their key
I’m not sure what you mean. Maybe you want to call Group.findSubGraphParts?
See image here i have group with name “Iteration (For Block)” with key id : ForKeyGroup—9C-C5-89-51-60-40-6E-04-08-8F-F1-AC-91-81-8F-B2
Now with the help of this i would like to find its children i.e. (Open Browser,Sync browser,Click etc)
I don’t know how to get this Group Object (“Group.findSubGraphParts”)
Diagram.findNodeForKey will return the Node or Group that has a particular key in the model.
Then you can use Group.memberParts to get a go.Iterator for the immediate members of the group, or call Group.findSubGraphParts to get all members of the group including ones nested inside member groups.
