hello,
a little question about connection.
I have a connection and around it some labels.
I use the same pattern (special Locater) as that described in the
article "Display a UML Diagram using Draw2D".
Now I am faced with the DirectEdit problem.
The editPart subscribes one and only one DIRECTEDIT request but I have
find the right label (one over about not less than 5)) according to the
mouse click.
Who have to make such a lookup (me or GEF ...). I guess it is my job,
but where is the best place ?
thanks in advance

hello randy,
thank you for the reply, but I hope that GEF do it automaticly for me.
I will implement such a solution.

graphical editpart, or how many properties are direct-editable.

hello,
Just for information, I have not less than 5 labels inside the
connection. So have too make something good not just a hack, and that is
my problem.
I forward the point obtained by the request.getLocation() to the figure
which calls the findFigure method and I obtain the good Label.
But now I am faced with another problems :
how to update the underlying label during direct edition (using
showCurrentEditValue of the directEditPolicy). The Figure knows about
the different labels (it create them), and knows about the association
String/Figure. The editPart knows about string but nothing about labels
(it job is to forward the string to the connection which convert it into
a label) and the association String/label is made internally by the
figure. I am not sure if I am clear : but currently to find the label to
update I have to lookup the figure associated to the editPart associated
to the policy. This is not really nice. If I break something, the
editpart has too much knowledges about the internals of the figure. This
is my first dilemna.
how to update the string in the model. I have 1 method per string to
update in the model. Another time, I have to lookup the label which is
in the figure to find the good method. This is not nice too.
If I remember the directEditRequest has a feature field which could be
used for such a problem, but nobody set it (in 2.1.x). But two
DirectEditRequest are created : one to initiate the directEdit and one
to terminate the directEdit. This is not cool as I have to copy the
feature field between the two creations, and it looks like a hack.
I hope I have clearly explained the problem.

Ok, great separation. So the connection figure needs to provide more
services to the editpart. Add some more API for the editpart to use. Such
as getLabelPropertyAt(Point).

Yes, there is a discriminator field on the direct edit request for these
purposes. If it doesn't work, open a bugzilla.

I've runned into the same problem: two request instances and the
feature field is not copied between them (by GEF).
I didn't found a bug report in bugzilla – should there be one? Or
should the feature field be copied by my application somewhere? If yes
– where?
I assume that this problem always occurs if one figure/editpart has
more than one "editable" label, doesn't it?

Open a bugzilla. The workaround is to override createDirectEditRequest()
and set the feature.
