Hi guys,
We are looking to represent complex diagram, that rely on the ability to
drag and drop Java elements (and others) onto the main design area. Could
you setup a three pane editor, two on the left (vertically) and one main
work area on the right? Could you integrate this into one editor?
Also can be have the file (that the editor acts on) either XML or text?
The example seems to be some binary representation of the diagram.
Thanks in advance.
Jon

Ok, see what your saying.
We ideally want to serialize the data into XML, and allow the user to modify
the XML independantly of the editor. However, how would we persist layout
values, as this doesn't make sense to persist in the XML.
We could have a dual format, representing the content in the XML, and the
appearance in a flattened object file? This sounds messy to me?
Any advice would be great.
Cheers.
Jon
