Problem Context:
I am developing a RCP based real time application. Objective of the application is to capture real time events (~200/sec) from information bus and display them in a tree format.
Tree hierarchy is required because events received, have parent child relationship I.e. an event received can be a parent event by it self or can be child of any already present event.
Right now I am using TreeViewer,Tree and TreeColumn to achieve above requirement.
Problem Statement:
As mentioned above, newly added event need to appear in Tree view as soon it arrives. I wanted to update only a specific node for which child event has been added, instead of refreshing whole tree which will lead to flicker. Is it possible and how?

Are you changing the structure of the tree, or changing the name of nodes,
or both?

I am changing the structure of the tree.
Seems,have got the solution. We can refresh a particular node instaed of complete tree. Thanks for the help.

I am already using add method but was unaware of the method refresh that can refresh only a particular node.
Now I am using it and it is working. Thanks for the help.

I am building up an Eclipse-RCP based application.
I have already tried organizing my code in MVC pattern, but wondering weather I can get better by usage of Spring IOC?
