Hello
I'm now working on my little GEF-RCP .
As data source of my program is a pile of XML-files, which have m-to-n
relations among them.
What I don't know how is - how can I use these to initialize the GEF's
Model and make the grapgical editor begin to run ?
I have read the Exsample 'Shape Diagramm Editor' , but in that case..
the user creates a file named 'xxxxx.shapes' , and double-click , then
the GEF-Editor starts..
And in My case , what I need is -- comparing to 'Shape Diagramm Editor'
1. the GEF Editor begins to open itself via other actions - e.g. I click
on a project name in tree viewer / package viewer
2. When the Editor opens itself , there shouldn't be empty and waiting
for painting, but it should read the java objects I prepared , to create
figures.
I hope i've expressed it understandable...
thank you in advance
Pei

Hi Payton,
GEF does not decide how you should read and write your model, it is
completely up to the application.
The shapes diagram is the example to follow.
Opening a file named 'xxxxx.shapes' causes ShapesDiagram.setInput() to be
called which reads in the file (as a steam) into the ShapesDiagram model
object. ShapesDiagram.initializeGraphicalViewer then uses the ShapesDiagram
model object to load the diagram using the ShapesEditPartFactory.
Cheers...
