saveState(IMemento) is about saving view state across sessions. The user shuts down eclipse, and the user expects to see his views when he restarts eclipse. The workbench uses saveState(*)/restoreState(*) for that.

When a user closes a view, he deliberatly closed it. It's gone. When the user shows the view again, it comes up in it's default state.

You have 2 options. Option 1 is to implement ISaveablePart, and when the view is closed it will get its methods like isDirty() and doSave(*) called. Of course if you mark your view as dirty, a little '*' appears in the tab title in 3.2.

Option 2 is to use DialogSettings to persist view information.

Thanks for this tip , I was making a choice between extending IDE or creating own RCP . It is good to know that with RCP also its just one line to enable saving of current perspective . I like to know is there any easy way through which I can identify the plugin required for my RCP project. Right now I am bundling entire Platform binaries just to avoid build erroes
