Don't use GMF for a form based diagram ? [message #188921]

Hi all,

I'm started a new project which final product will provide a graphical
editor based on GEF.

I'm wondering the relevance to use EMF and GMF. After a fast take in hand
of EMF I'm convinced of its usefulness in this project. This is not the
case for GMF.

I've read on the following presentation (slide 7) that I musn't use GMF if
the diagrams (I wan't to be able to build with my graphical editor) are
only form based, with no connection, edge or node... That's the case in my
project. So why shoun't I use GMF? Can't I take advantage of features such
as predifined graphical components, bridge between EMF and GEF, ...

Thanks for any help.

If you are using GEF, and if you find EMF useful, there is no reason not to
use GMF, in my opinion. At a minimum, GMF will help you manage your code,
by providing a good package and class structure.

As I see it, GMF is oriented on making the XY layout work well, and offers
some support for the List layout, though not full support.

The form and table layouts will need to be implemented by you, which will be
a hard task, in my opinion, as you have to do it all by hand. However, if
you started implementing it in GEF, you could port it in GMF easily, once
you get used to the new project structure.
