Hi!
Is it possible to put GEF editor into CompareEditor?
I want to compare two diagrams drawed in GEF.
I am able now to compare models of diagrams - i have found all differences,
now i want to show
those differences on diagrams.
It would be cool if it can be shown as CVS differences.
One editor splitted into two editors - each contains one GEF diagram.
I am not sure if it is clear.
So my question is.
1) Should I try to do it in CompareEditor (how)?
2) Should I try to do it in one GEFEditor splitting my editor and drawing
diagrams with differences (but disabling any edit policies) ?
3) If should I choose option 2 - how to make scrollbars which can scroll
both diagrams identically (like CVS Comparator).
Sorry for my english :)

Sounds like an interesting undertaking.

Don't know anything about CompareEditor, but I would guess it's text-based
and hence you'd have to write your own editor. How is your model persisted?
XML? If it is text-based, you might be able to re-use some features from
(or delegate that functionality to) the CompareEditor: parsing, identifying
differences, etc.

Yes. You'd have two graphical viewers in this one editor. You might even
want to throw in the difference tree at the top ... which could esentially
be the difference in the outline page of the two file versions. Perhaps the
editor on the left (the workspace version) could have its edit policies
enabled so that the user can "merge" any changes manually.

That should be the least of your worries at the moment. Suffice it to say
it's possible. (In the logic example, the rulers are in different graphical
viewers with their scroll bars always hidden. Scrolling the main graphical
viewer then forwards those events to the respective ruler viewer. You can
look at it if you want more info.) Perhaps you might decide, in time, that
it's best to just show the two as individually-scrolling viewers and let the
user handle the merging.
Other interesting questions would be is this semantically possible (I guess
the answer to that depends on your model). How, if at all, would you
highlight the differences? Maybe modified figures would be highlighted or
have a different color. What about differences in the file that are not
graphical (for instance, version of xml or something)? Maybe they can be
grouped under a separate category in the difference tree.
Just my two cents. Obviously, we've never tried anything like this before,
so it's going to be a trial and error procedure.

No. It's not a XML. It's not text based. It's my complicated model.
So I can't use a text comparing. It's not hard to me to find differences -
because I have done this.
I have model of my differnces so now only what I need to do is to show
differences on my diagrams.

File version is not so important. There will be no possibility to merging
changes.
I wish only to _show_ differences.

For now I decided to do it in this way. Two scrolling viewers.

Yes. There are few levels of differences. Each of will be displayed by
different colors.
So - changing size or locations is not so important as changing outputs of
elements, or adding new elements to diagram, or changing attributes in
elements.
Differences which are not graphical - version of file will be displayed
earlier - because two models for comparing will be taken from CVS-like
database.
So version like (1.1, 1.2 etc..) could be displayed as title of viewer :)

Like whole my project :)))
Sorry for my english :)

The topic of cropping connections has come up quite often in the newsgroup.
We'll add it to the FAQs or something. Meanwhile, please search this
newsgroup.
