Hi,
I am having couple of views with treeViewers. I want to pass the selection
of treeviewer in one view to the other view. Anybody have any idea abt it.
(I want something like IEditorInput).

Currently I am using showView() API to open the secong view.

Thanks,
Dinesh

Hi.

A few ways spring to mind.

1 - Using singleton static getInstance() methods in the views.
By statically referencing the views, like this:
View1{
method(){
View2.getInstance().newSelection(selection);
}

View2{
public static View2 getInstance(){
return instance;
}
public void newSelection(...){
// do stuff
}
}

2 - Using ViewPart.setSelectionProvider(treeviewer)
register selection provider in one view (can be a tree viewer):
this.getSite().setSelectionProvider(theTreeViewer);

and register selectionchangedlistener in some other view:
this.getSite().getSelectionProvider().addSelectionChangedLis tener(aSelection
ChangedListener);

Good luck,
Emil

I don't recommend (1) because you can have more the one workbench page
open at a time, and each could have an instance of your view. So there
is no one static instance.

Right. What I sometimes do is to provide a domain for every window/worbench
page
and allow to also listen up to a global change which changes depending on
the local changes.

Registering the domain is just easy by using a singelton domain context
manager and map the domains depending on the window/workbench page.

Works well here... .

Bye

Thanks a lot, The second option worked fine for me. I didn't tested with the
first one.

Thanks,
