Newbie - Where do i start [message #153209]

I have been reading a lot about GEF and want to implement a workflow
designer using GEF. I understand the MVC concept and all that, but
frankly speaking I have no clue where do I start from!!
Can someone point me to a basic step by step tutorial that will tell me
how to go about creating a very very basic GEF application so that I
atleast get a head start (e.g. where do these classes go, which is the
base class, how does it get called, should I write a plugin or a
application etc)?
I know I may be asking for too much but really I am lost on my first
application in GEF. All of the tutorials/articles talk at abstract level
and give little code snippets.

Thanks in advance

You should read the following article on the eclipse-wiki.info site:

On http://eclipse-wiki.info/GefDescription there is an article of GEF
and I think that's one of the best step by step tutorial for GEF I have
read. And I believe it will also save you a lot of time.
Good Luck! :)

Martin and Greenbank, thank for the reference.

Fill surely get back to bother guys @ ETG if I have doubts ;).

There should be a new example in the latest integration builds. It's called
the "shapes" example and is very basic.

Hi Randy,

Thanks for the pointer, there is infact a new example.
However when I try to run it I get the following error
The selection wizard could not be started
Reason:
Plug-in org.eclipse.gef.example.Shapes was unable to load class
org.eclipse.examples.shapes.shapeCreationWizard

Anyways, I will try to go through the source and figure out if I can get
some clue.
Thanks again
