By using WorkbechWindow's SelectionService u can acces view's selection from another View.

Step1: First u have to set the ListViewer as ViewSite's Selection Provider.
eg: getSite.setSelectionProvider(ListViewer);

step2: In the view, in which the selection of ListViewer to be reflected, u have to write one listener (ISelectionListener)..
eg: private ISelectionListener selectionListener = new ISelectionListener() {
public void selectionChanged(IWorkbenchPart sourcepart, ISelection selection){
if (sourcepart instanceof SOURCEVIEW){
if (selection instanceof IStructuredSelection){
IStructuredSelection ss = (IStructuredSelection) selection;
...
...

thank you for ur great help

Another case:

if i want to listen to doubleClick not for a selection (Singleclick) like that:

if i doubleClick at an item in ListViewer (in acertain view),
then an action must happen at another View.

Hi,

I'd solve this using the Command-Handler-Service:

1. Register Command in plugin.xml
2. View 2 adds his self as a listener to the command
3. View 1 listens for DD and executes the command

There's been a resent thread where I posted a lot of code you can use to
make this happen for you. The name of the thread was "Design-Question
regarding Actions and th UI".

Those are in Eclipse 3.3M6, but not in Eclipse 3.2. What version are you developing against?

Refreshing a view works in 3.2; you just can't rely on those packages and IApplication class. But you can have a PlatformRunnable and launch with -application; you just use the older code.

In short; I don't know where you got the IApplication idea from, but that's for 3.3 only. Get rid of that, and use the PlatformRunnable as described in the Eclipse 3.2 help, and you'll be sorted.
