[mitk-users] BlueBerry question: Change data node selection from editor

[Miklos Espak]

Hi,

we have a custom editor (aka. DnD Display) that can contain multiple image
viewers for viewing images side by side.

I would like to maintain the data node selection for each internal viewer,
so that when the user changes the selected (focused) viewer, the earlier
data manager selection for that viewer is restored, and (!) all the views
are notified about the selection change and update their status.

I cannot figure out, how to do that. :-(

The editor derives from QmitkAbstractRenderEditor and
mitk::ILinkedRenderWindowPart, and it receives a signal when the selection
has to be changed.

I tried this but the views are not notified:

void MultiViewerEditor::OnSelectionChanged()

{

berry::IWorkbenchWindow::Pointer workbenchWindow =
this->GetSite()->GetWorkbenchWindow();

berry::ISelectionService* workbenchWindowSelectionService =
workbenchWindow->GetSelectionService();

berry::ISelection::ConstPointer selection =
workbenchWindowSelectionService->GetSelection("org.mitk.views.datamanager");


berry::IViewPart::Pointer dataManagerView =
workbenchWindow->GetActivePage()->FindView("org.mitk.views.datamanager");


QmitkDataNodeSelectionProvider::Pointer dataManagerSelectionProvider =

dataManagerView->GetSite()->GetSelectionProvider().Cast<QmitkDataNodeSelectionProvider>();

dataManagerSelectionProvider->SetSelection(selection);

}


Any idea?

Cheers,
Miklos

OK, I got it work. The editor had to register its own selection provider. I
copied the implementation from QmitkAbstractView.

Cheers,
