Model Explorer (navigator) in GMF [message #167516]

Hi All,

I'm relatively new to GMF, and I'm having some difficulty around the subject of navigation. I have tried the GMF navigator, and it seems like a decent solution for a single-partition GMF application. However, I think I'm going to end up using two diagrams, as described in the Diagram Partitioning wiki (http://wiki.eclipse.org/Diagram_Partitioning). It doesn't seem to me that I'll be able to use a single navigator to view my model by using the navigator in either of my generated gmfgen files. Is that a fair assessment of the current GMF navigator functionality, or is there some way to tweak it so that a single navigator would include objects from both partitions?

Assuming that I can't and that I have to create my own navigator, can anyone point me in the right direction for how to create one? I've created a view plugin that includes a Tree-style explorer, but I'm not sure of the best way to "connect" the model to the tree. I could traverse it myself, but it seems to me there's got to be a better way to render objects from an EMF model. Any thoughts?

Thanks in advance,

Brad.

it should be possible. Try using the same diagram file extension for the
second diagram and you'll probably get it working.
Even in case of failure I suggest you yo modify GMF-generated navigator (providers)
- it should be pretty straightforward to let it working and visualizing both
diagram contents in the same tree.
