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

[bogdanditrsrc@xxxxxxxxx (Bogdan)]

Hello,

I am writing a plug-in (using Eclipse 3.4) and I want to be notified if a 
user opens a file using CTRL+click (open declaration) in a Java source 
code file.

So far, I added a IExecutionListener to a ICommandService for the current 
workbench window:

IWorkbenchWindow window = 
PlatformUI.getWorkbench().getWorkbenchWindows()[0];

ICommandService service = (ICommandService) 
window.getService(ICommandService.class);
service.addExecutionListener(new IExecutionListener() {

//? other methods (notHandled, postExecuteFailure, postExecuteSuccess)

    public void preExecute(String commandId, ExecutionEvent event) {
			//check for "open declaration" events
    }
});

This code works fine (I triggers an ?open declaration? event which I catch 
it inside the preExecute function) but ONLY in the following TWO cases: 1) 
if I press F3 (Open declaration) or 2) Go to menu ?Navigate->Open 
Declaration F3?. However, when I use CTRL+click (which the documentation 
says should do the same thing (open declaration)), that event does not 
trigger my preExecute function.

I also added an IPartListener to the active Workbench page to notify me 
when a new file is being opened. This notifies me when a new file was 
opened, but it does not tell me the source of the event (whether it was 
CTRL+click, a file opened from the Package Explorer, a file opened from 
Tabs, etc.)

IWorkbenchPage page=window.getActivePage();
page.addPartListener(new IPartListener()
{
	//...other methods partOpened, partDeactivated, partClosed, 
partBroughtToTop
	public void partActivated(IWorkbenchPart arg0)
	{
		// notifies if a file was opened
		//does not provide the source of the event (CTRL+click, package 
explorer, opened files in tabs)

	}
});

I was wondering if there is any other mechanism (listener) that could 
notify me when the user presses CTRL+click, such as a listener for 
actions, a source for where the action was generated or triggered, or 
anything else. I searched for hyperlinks, editor listener, mouse hover, 
etc., but nothing worked.

I would really appreciate any information that could help me solve this.

Thank you
