Pass object to a View (via Constructor) [message #759688]

Hi,

i need to pass an object to a view.

I basically have a view with a list of objects, i also have a command "Open second View" to open another view. What i now want is to make it so that the selected object in the list view, is passed to the second view if i exectue the "Open second View" command. I'm able to get the selected object from the ListView in the command handler via

ISelection selection = view.getSite().getSelectionProvider().getSelection();

but i don't know how to pass the object to the second view via a constructor, cause of the way the view is constructed:

window.getActivePage().showView(SecondView.ID);

So how can i pass the object the moment the second View is constructed (aka in the constructor) ?

You can't pass that into the constructor. The most common method of communicating between 2 views is to use the IWorkbenchWindow selection service. See Using the Selection Service.

The other way is for the 2 views to share a common manager or go-between (basically re-implementing a smaller version of the window selection service). Then you could pass the object to the manager, show the view, and have the view get the object from the manager in its init(*) or createPartControl(*) method.
