Hi to all, i am developing an rcp, i add a perspective with the ID org.python.pydev.ui.PythonPerspective

When i tried to switch between perspectives from my rcp app, with this code:

MPerspective element = (MPerspective) modelService.find("org.python.pydev.ui.PythonPerspective", app);
		
		partService.switchPerspective(element);

the perspective change but nothing appear.

I added the Pydev into my plg dependencies.

Can you give me an idea about what is happening

Thanks.

PD: I use the same way in e3 and works.

Esteban,

The code looks good; are you properly getting modelService and application via injection ?

As an example, I would give them value via injection using a handler, like below:


public class SwitchPerspectiveHandler {

	@Execute
	public void execute( EPartService partService, EModelService modelService, MApplication application) {

		MPerspective element = (MPerspective) modelService.find("org.python.pydev.ui.PythonPerspective", application);

		// switch perspective
		partService.switchPerspective(element);
	}

}

Regards,
Patrik

Well PyDev needs to compat layer not? Are you running the compat layer?

Hi Patrik, yes i get modelService and application via injection. Here is my code

public class ShowPyDevPerspective 
{
	@Execute
	public void execute(MApplication app, EPartService partService, EModelService modelService) 
	{
		MPerspective element = (MPerspective) modelService.find("org.python.pydev.ui.PythonPerspective", app);
		partService.switchPerspective(element);
	}
}

I need add perspective like i show in the image ?

index.php/fa/26498/0/

Thanks for the anwser.

PD: I add the compability layer (http://www.vogella.com/tutorials/Eclipse4MigrationGuide/article.html#using-the-compatibility-mode)

* org.eclipse.rcp
* org.eclipse.emf.ecore
* org.eclipse.emf.common

in my plugin.xml

Are you trying to do a mixed mode e4 application? From my memories this
mixed mode stuff has never really worked. If you need something from the
3.x world you need to solely bet on the compat-layer and let it control
the model.

Hi Tom,

My rcp is pure an e4 and here is where i dont understand, is neccesary use the compatibility layer with Pydev?

If the answer is no; why using the code to switch perspectives, the PyDev not appear, what is missing?

Thanks.

Regards.

You are trying to include some 3.x plugins into a plain e4 application. And this is what doesn't work that easy. There are some tutorials out there that show that it is possible somehow, but you need to know the exact workarounds. Sorry, I don't have the links right now.

The other approach is to create an Eclipse 3 application, which means your application will run on the compat layer. And then you can add E4 stuff step by step until you are not able to migrate anymore. This is a mixed mode application starting from e3 which is working quite good. I wrote a tutorial about that, but it is only available in German.

Yes PyDev requires the compat layer to be in charge of the application
bootstraping. eg you need to launch with an IApplication who bootstraps
the complete RCP-3.x Framework.
