How to have a Dialog be a ISelectionListener [message #500330]

Hi,

This question is a bit similar to one asked previously so apologies for the repeat.

I have a dialog which I would like to register as a selection listener with a selection service. Within the application we have a view containing a table and when a user selects a row in the table an update should be passed to the dialog. The view implements ISelectionProvider.

The dialog implements ISelectionListener but as it is a Dialog I am not able to directly access the selection service. What should I do to achieve the following

getSite().getPage().addSelectionListener(..);

Thanks
Andy

No sure if this will work, but might be worth a try:

ISelectionService iss = (ISelectionService) PlatformUi.getWorkbench().getService(ISelectionService.class );
iss.addSelectionListener(yourSelectionListener);

Also, your post says that your View implements ISelectionProvider, but I think the table needs to be set as the selection provider via:
viewPart.getSite().setSelectionProvider(yourTableviewer).

Isn't a wizard modal? That is, when it opens, the selection should already
be done? Can you record the selection somewhere for the wizard to access?

This is not a wizard dialog but just a modeless dialog so the user can still interact with the main part of the GUI while having the dialog open. Under normal circumstances the user will open a dialog perform an action and the close it. We have a use case from one user where they want to keep the dialog open and reuse it rather than close it down.

We may end up changing the dialog into a view but for our first versio of the app we just want to get something out there and get feedback.

Thanks for all comments.

That did not work for me but this did

PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().addSelectionListener(mySelectionListener)

Thanks
