[news.eclipse.newcomer] Re: How can I get notified when CTRL+click (open

[bogdanditrsrc@xxxxxxxxx (Bogdan Dit)]

Hi Dani,

I added a part listener so that I can find out when the editor was 
opened/activated. However, I don't know how to look in the stack to see 
the event that triggers it. Can you please tell me the class name of the 
stack/listener?

Here is my part listener code:

IWorkbenchPage page=window.getActivePage();
page.addPartListener(new IPartListener()
{
//...other methods partOpened, partDeactivated, partClosed, 
partBroughtToTop
public void partActivated(IWorkbenchPart part)
{
	if (part instanceof EditorPart)
	{
		//a new file was activated in the editor
		
		//How can I look at the stack to see what triggered?
	}
}
});

Thank you,
Bogdan
