I am currently building a graphical editor using GEF. My model classes all
implement the IPropertySource interface, and I observed the following
behavior:
- If one edit part is selected in the editor, the appropriate properties
show up in the property sheet view, as expected.
- If I select multiple edit parts that correspond to model objects of the
same type, the properties of the first selected part are displayed (which
is fine with me, too).
- When I select edit parts of different types, the property sheet view
displays nothing.
I'd prefer if the property sheet always displayed the properties of the
model belonging to the first selected edit part, no matter of what types
the other selected parts are. Can someone give me a hint on where the
decision about which model's properties are displayed takes place?
Thanks a lot!
Regards, Ralph

This is done in PropertySheetEntry, an internal implemenation of the public
interface. Is it really common for users to select multiple object, but
only want to edit the properties of the first?

So, no luck here, I guess.

You are right: in general, this is not what a user would expect. The
reason why I would like it to behave that way is the following: The editor
I am developing is an ER diagram editor. If the user selects a foreign key
edit part, I want the correspondent relationship (connection) part to be
highlighted aswell (programmatically), so that the user can see at a
glance which entity the foreign key comes from. I still want the selected
foreign key to appear in the property sheet, because this is what the user
selected.
Is it possible to highlight the connection's figure (a PolylineConnection)
without selecting it? I mean, to make the figure appear as if it was
selected without actually setting it's state to selected? I tried
requestFocus() in Figure, but the doc does not reveal too much about what
this method's for, and it did not do what I want anyway.

If you just want to highlight the connections, you could forward an
arbitrary request type to the connections when the key is selected. In
other words:
For each key:
key.showSourceFeedback(new Request("KeySelected")); or something
