[news.eclipse.tools.gef] How to select and scroll to a figure programati

[vijay.rajonline@xxxxxxxxx (vijay )]

Hi,

I have created a tree type structure in which each branch has collapse and 
expand buttons in GEF,

currently on expand i am setting the whole model again(is there any other 
way)
after that i need the viewer to scroll to that particular node 
automatically..

A little direction would be appreciated...


thanks
