How to fill Part with Data? [message #957723]

Hi!

My goal is: With a doubleclick in a selected Item in a Table (Example: a name of a person in a list), a new Part should open (which shows me the details of the person).

What I've done till now: Use SelectionService when I hit doubleclick. Then using the Command- and HandlerService to open my Handler. In this handler I use a PartDescriptor to make a new Part, use the SelectionService to get the Selection of the part where i selected it, and finally I use the PartService to show the part.

So far so good (or do you think there a better way to do this?).

My Problem: How can I get the data of the selected item to fill the part-fields (name, address etc)? Should I use a InputPart to set the Uri (part.setInputUri)? What is that Uri and where should it point?

All-in-All: How can relize the functionality of editor and editorinput in 3.x?

Thank you!

I use the inputURI approach in my apps. The URI can be anything that you like: the workbench doesn't check for conformance. So you could use "x-myapp:DB-UUID" if the data can be pulled from a database, a "data:" URI with base64-encoded serialized details, 'file:" if an on-disk file, etc.

Well it depends on your model I guess. Do you have the object itself in the table? Then you might want to use the SelectionService and inject your object into your part via @Active annotation into your part. Then you can put your data into the part elements like you did in an Eclipse 3.x app. If you have to load your data after double click, maybe the solution posted by Brian is more appropriate for your case.

thanks! yes I have the object itself in the table.
now I do it like this: use the SelectionsService in the handler to get the Selection and use the part.setObject(inputobject) methode. in the part use "@Active MPart activePart" and then I get the object via "activePart.getObject()"
what do you think about that?

I actually didn't get what do do so I could do it like "@Active SomeObject object".?

Have a look at the tutorials from Lars Vogel or Jonas Helming on selection service. You set the object that is selected to the selection service and implement a method in your second part that injects the active selection with @Named (IServiceConstants.ACTIVE_SELECTION) @Optional Object yourObject

Sorry for pointing into the wrong direction with @Active, I mixed them up by mistake

now I got it.
I missed that in the tutorial.

I finally set the hole IStructuredSelection-Object and use a Handler (where i use the @Named (ISer...)@Optionale...) as recommaneded) to open the part. Here I define to open more parts if have selected more Items in my Table. In the Handler I use the same procedure (setSelection...) and in the opened part I Inject the Object via @Named ...

I thinks that works fine.

Thanks for the help!
