Hi all,
I'm a newbie with GEF and am currently learning how to use it. I have read
some articles about how to get started and was able to create a basic
viewer with one feature. What I'm after, though, is a visualization of a
special XML file and now I don't know how to proceed from here.
Loading a DOM from the XML file is done already and I used the root
element as the content element for the root edit part. I created a factory
for the edit parts (some XML nodes will get own edit parts, other won't),
which is queried once to create the part for the root element. Now I want
to create the other edit parts too, but don't kow how. Am I supposed to
put the entire hierarchy completely and manually into GEF? I'd expect the
the top edit part would be queried about its potential children and there
I would have the opportunity to create the other edit parts. But somehow I
can't find anything like that so I think this is not the right way.
I hoped GEF would help me to simplify the task of creating the edit part
hierarchy but so far it looks as if I have to do everything manually when
initially setting up the editor. I would be very thankful for any hint or,
even better, a simple example. I've got that workflow project from IBM but
this is way to complex for a beginner and I can't even get it to build
error free.

GEF will build your editpart hierarchy for you. All you have to do is
implement getModelChildren() in your editpart.

I *knew* it would be something simple. Thank you Randy.
