Questions regarding Evaluation (Multiple Pages / PDF Export / Grid Layout ) [message #224468]

Hi List,

i'm new to GEF and currently evaluating some technologies for a
graphical editing project.I have some specific requirements and have
already skipped through some basic papers about GEF (The Shape Editor
example and the FAQ) but it would be nice if you could answer my
questions regarding some of my requirements. This would help me making
the decision if i should dive deeper into GEF or not.

The project is about a simple workflow editor with some constraints
regarding the layout of elements(figures) and export to file formats.
Basically each document/model consists of some metadata (author, date,
proofreader, etc.) and the actual workflow. The specific requirements are:

1.) The Editor must explicitly use multiple pages. A limited set of
elements can be placed onto a page inside a fixed grid. As far as i have
read there's a MultiPageEditor and LayoutManagers available. Are these
the tools to solve such kinds of problem? The examples in Eclipse 3.1
don't use these kinds of things (AFAIK). There are rather strong
limitations to the layout because of the corporate design of our customer.

2.) A view of the model must be exported via PDF. I know that this can
be done via a printer (would this respect multiple pages correctly?) but
are there any other techniques already there using pure java? An option
for me would be to transform the XML-model via XSL-FO into a PDF. But an
existing solution would be nicer anyway. It should provide hooks to
generate page-headers and footers (I know that this may be out of focus
of the GEF, but maybe someone has already faced this problem).

I know this is kinda specific but diving into a Framework (like GEF) is
always time consuming and for an existing user it's often easy to
estimate if some requirements are realistic or not.

Thanks very much in advance!

Best regards
Sebastian

Hi,
Maybe from omonodo UML tool you could get it.
