I must admit I find the .gmfgraph editor not exactly self-explanatory!
Is there some help or guidance on this available? The tutorial is rather
silent on this. So I am like staggering along through a dark forest
during the night, banging my head left and right.
I loaded a couple of default resources listed in the tutorial
("basic.gmfgraph", "classDiagram.gmfgraph" and "stateDiagram.gmfgraph")
and I am now trying to compose my own "widgets" by copy-pasting figure
gallery items from those over into my own figure gallery and then
defining my elements using the above as figures. Some work, some
don't.... I am e.g. trying to define a simple connection with an arrow
tip. For this I copied the "PolyLine Connection SolidLineWDstArrow" from
classDiagram.gmfgraph (which also references "Polyline Decoration
Arrow", which I copied over as well). If I now define a Connection "foo"
and try to set the "Figure" property to be the above "....
SolidLineWDstArrow", then as soon as I leave the property field its
content is reset to empty. I don't get why this is not accepted! Is
there something missing? But if so: what? There is no issue listed in
the Problem view, no error message displayed, no entry in the .log nor
anything similar. My input is just silently discarded and that's it :-(
When I got stuck with the above I tried whether I would get any further
with the "graphical designer" mentioned in the tutorial (i.e. I
installed the "Experimental SDK"). I created the gmfgraph_diagram file
and fired that editor up (guessing that this is how that's supposed to
work) and I see a couple of boxes with familiar names placed along the
top border, but then what? What is a user supposed to do, draw or
connect at this point? *Any* intro or explanation on this?

First, you don't need to copy figure to use it, the idea of figure galleries
is to have reusable libraries of figures, instead of redefining them each
time. Nevertheless, having your own copy should be possible, and the issues
you faced migth have something to do with EMF generated editor, rather than
with .gmfgraph model itself
Experimental designer gives you space to create new figures and diagram
elements, relate them with links. Though I won't recommend it to study
..gmfgraph.

I tried exactly that - i.e. instead of defining my own figure gallery I
loaded the ".../basic.gmfgraph" file and then tried to assign a figure
from that gallery (e.g. "Rectangle NodeRectangle") to a node that I had
defined. But that exhibits exactly the behavior that I described: As
soon as I leave the drop-down field the field is empty again, i.e. my
selection (even though it is displayed as one of the options in the
drop-down list) is apparently not accepted.

??? But what is it then good for? The way that note in the tutorial was
phrased, I thought it was exactly for that purpose, namely to generate
the visual representations (i.e. eventually the .gmfgraph file) required
for the GMF mapping step. Shouldn't it then also be possible to
visualize existing .gmfgraph files? I'm lost...

Hmm, apparently, a fix for a different problem introduced in a meantime made
this not possible :(
Copy-pasting figure works, however.

I won't recommend it just because it's (a) *experimental* and (b) we do not
pay a lot of attention to making it nice and sophisticated. Though, it's
functional to certain extend.
