Architecture of Graphiti Diagram Editor [message #1059736]

Hi,
I want to create a Graphiti Editor (Diagram A) where the user can create several elements.
Now when I doubleclick on an element, another Graphiti Editor (Diagram B) shall be opened, to model the internals.

1) I created a plug-in along with a DiagramTypeProvider and a DiagramType. This one is for Diagram A

My question now is how shall the architecture of the editor look like?

Should I create another plug-in with DiagramTypeProvider and DiagramType for Diagram B. Or can I just add another DiagramTypeProvider and DiagramType to my existing plug-in?

For the sake of diagram navigation, I saw the "AbstractDrillDownFeature", which pretty much looks like what I want to achive. Would it be the right direction to go? Are there any tutorials / examples for similar projects?

Thanks,
Matthias

Matthias,

While it certainly is possible to have separate editors and open one
from the other, it may be easier for the user to work within one
multi-page editor, with one undo-stack, easier navigation etc. In
addition, having separate editors also means splitting the diagrams in
separate files.

Matthias,

I cannot provide a clear answer to that, but it depends on what you want to
achieve. Usually splitting up different parts into separate plugins is a
good idea and you will end up with cleaner coding and architecture because
you are forced to think about APIs and reuse...

The AbstractDrillDownFeature would be a way to go, I could also imagine
using a CustomFeature registered as DoubleClickFetaure to start a new
diagram editor.
