Create Diagram from xml source [message #484860]

Hi.

My application should be able to create a gmf diagram from an xml
resource. I am able to create the neccessary xml resource programmatically
from my source file.

How can I create the diagram now using this xml source? So far I was just
copy/pasting the xml code into my diagram file.
The problem with that is, that when I don't modify and change it, the next
time I open this diagram file, it appears to be empty..

Is there a method I can pass an xml source for the neccessary diagram
information?

Any help will be very nice :) Thanks.

Artur

Hello Artur,

Try Init ??? diagram file action from the popup menu of your model file.

Hi Alex,

thank you for your relpy.

I looked into that action and I can actually do that. But I wanted to do
it programmatically. So I would create my model file in the memory and
give the root of that xml object as an EObject into the method of the init
file. I think this would work.

What I did now is just writing the whole template file myself (My model
and diagram information are in the same file). I just dump that file into
the workspace and I can open it. Everything is fine.

I had a problem with the connections and empty diagrams because the
diagram information wasn't saved right aways. However, if I remove the
semantic hints from the node and the edge from the plugin XML everything
seems to be working.

Is that a way I should do that, or would it cause problems later on if I
don't create my diagrams with the init action of gmf? It seems to me that
the init actions is creating the same file I do manually?

Best regards,
Artur

Hello Artur,

I think it make sence to use code (like in init action) to create your diagram
file programatically.
If you simply generate code from the model then it looks error-prone for
me, but you can use this technique if it works for you.
