Hi all !

I work on a EMF/GMF application.

I have an ecore file.
I have an Eclass with an attribute which have a Map type.

map in my application ?

Thanks for this answer !

I did these modifications.

But in my application, I have a problem to edit this map and add entries
to this map.

In 'Property' tabs, when I click on my attribute to edit this attribute, a
popup is opened. This popup contains 2 sets : 'Choices' and 'Feature'.
Theses sets are empty.

I would like add entries to the map by dint of a 'key' value and the value
matching with it.

Is it possible to do this ?

Thanks

Guillaume

You could look at EAnnotation's details EMap as an example and how the
Sample Ecore Editor supports editing it.

Did you make your map feature a containment reference? I don't think
you should expect to be editing the map as a whole but rather be
creating new entries via the normal child creation approach and the
using the properties view to set the key and value (as in the Sample
Ecore Editor). Give you likely made a mistake, you'll probably need to
fiddle with the GenFeature properties for this feature to make sure
Children and Child Creation are enabled and to turn off the property
support for it.

Yep. Creating an EAnnotation and then children for that in the Sample
Ecore Editor will be agood example to look at.

I did these modifications and generated 'editor code'. It works fine for
this application.

But I work on a RCP application and I don't have a 'tree' representation
but a diagram.

Ideally, when I click on the attribute in 'Properties view', I would like
to open a SWT window with the view of the Map inside.
An example could be that : in your Eclipse IDE, Windows/Preferences >
Run/Debug > String Substitution. You have two columns (variable and value)
and buttons 'New', 'Edit' and 'Remove'. Is it possible to do that or
something like that.

Thanks

Guillaume

It's certainly possible to create a specialized dialog cell editor for
that purpose; there was a recent GMF thread about how to do that for
GMF. There's an EMF recipe for this as well...

Certainly, but you'd need to build this yourself. An EMap is
effectively a list of contained map entry instances; you might want to
use data binding for building something like this. You'd want the
dialog to be working with a copy of the list and its content and then
use a command to update the map as a whole when the user clicks OK.
