How to stop the Eclipse editor from closing in RCP

Question

I am working on Rcl based on Eclipse. We need to prevent the user from closing one of the open editors.

Desired behavior:

• user presses X in the editor window or "CTRL + W"
• a dialog box appears that says: "If you close this editor, your activity will stop. Do you want to?"
• if they click yes, it closes; if not, it remains open.

Oh yes, and is it possible?

Thanks dk

        } catch (PartInitException e) {
            e.printStackTrace();
        }
    }
