I am considering to use VE as a base for a rich-client-platform which is
used to visually edit my own beans. Here is some more information about it:
- The beans actually do *not* have anything to do with GUI.
- Almost all the beans have an output and input port. These ports may be
connected to each other to form a 'pipeline'. This requires a different
GEF editor to what VE offers.
- The pipeline starts from a source and ends to a sink. The equivalent of
the 'visual pipeline' is needed at the end as some java source code.
And here are my questions from the VE team:
1) It seems to me that, among the other eclipse tools, VE has a lot of
common features to my project. Please correct me if I am wrong.
2) Assuming the above to be true, I need to customise VE to fit my
requirements. This would include overriding the editor class and the
property sheet. Where is the good point to start that? To be honest I feel
quite lost as I cannot find any documentations of VE for programmers.
Thanks
Aureliano
PS Thanks to Rich Kulp for the useful discussions on using jni-beans in VE.

Yes, we do some things like this. But what we do is also different
enough that I'm pretty sure you can't just use our code.
On the other hand, the VE code might be a good example of how to do the
kinds of things you need to do. if you ask specific questions about
where certain things are in the code, I'm sure folks will be happy to help.

I'm sorry about your post getting lost...
One of the other team members, please correct me if I'm wrong, but I'm
not sure that extending VE would be your best bet here. VE is really
intended to model graphical user interfaces.
But programming to GEF directly would probably be a good approach.
In fact, the electrical diagram example supplied with GEF does a lot of
the kinds of things you're talking about....

Hi David
Thanks a lot for your answer. Two least reasons that I was going to use
VE, as mentioned before, is that:
1) I need to associate each figure in the diagram to a 'live bean'.
2) I need to auto-generate a (java) source code for the diagram.
It seems to me VE is the only eclipse project that has this features -
please correct me if I'm wrong!
