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?

Hi,

Why don't you use the add(*) methods instead of refreshing the whole tree?

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

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?

Hi,

why don't use the newly developed databinding framework? I'm currently
developing an XML-Dialect to completely do gui-design/databinding in XML
but it is at the very early stages, I think this is the future for
datadriven applications written in SWT whether you use the databinding
component directly or through some layer.
