I need to get a reference to the View from a Node.
Which GoView? There might be several showing a node, or there might be none.
What do you really want to do?
The GoView that the Node is currently on. I want to call a method on the View from a node on it.The documentation shows a View property on the Node but says it's null unless the node is in a layer.
A GoDocument can be displayed by any number of views... so the nodes don't know what view(s) they are in. What you are talking about is "view specific" GoObjects like selection handles (see the section on Ownership in the User Guide).
Typically, EventHandlers will be called with view context if you might need that. What’s your situation?
It’s easier to add state to the GoDocument rather than to the GoView, for various reasons. GoObject.Document will be non-null for those objects you have added to the GoView.Document in order to display them in the view.
GoObject.View will be non-null only for those special objects that are explicitly added to the view’s layers. Jake mentioned selection handles, but there is also the view’s grid and (optional) sheet of paper.
