Hi to all,
I don’t see any “+” (i.e. expandable) handles in your screenshot.
Here I want to show u that a node in screen shot with name “D-Modem” does not has any child below it.
But this still shows “-” sign which is not right logically.
we not want to show “-” sign in that node which does not have any child.
A GraphNode may have an InPort and an OutPort. To determine if a GraphNode has children, you probably want to be checking that OutPort is not null and that this.OutPort.DestinationLinksCount > 0.
