How to take active parts with EPartService?

Question

I want to take active parts by using EPartService. Can I use EPartService for this?

Answer 1

If you want to get the active part in something like a command handler you can inject it as a parameter:

@Execute
public void execute(@Named(IServiceConstants.ACTIVE_PART) MPart activePart)
{
  ... handler code
}

If you want a list of all currently displayed parts you can use the EPartService. Something like:

@Inject
MApplication app;

@Inject
EPartService partService;

// Find all the `MPart` objects in the current presentation

Collection<MPart> parts = partService.getParts();

// Filter the list to include just the parts that are current being displayed (rendered)

parts = parts.stream().filter(MPart::isToBeRendered).collect(Collectors.toList());

Note: This code requires Java 8
