[news.eclipse.platform.rcp] Need a View like the Console view in IDE

[Guofeng Zhang <guofeng@xxxxxxxxxxxxx>]

Hi,

I need a view that behave like IDE's Console view, that is,
  (1)It is created if it does not exist on the perspective when some 
event occurs,
  (2)It is brought to the top on the perspective if it does not when 
some event occurs.

Please tell me where I can find the sample code or article about it. I 
search about it but do not find what I need.

Thanks for your help.
