<pre wrap="">Dear all,
let me explain my use case first:
I have two models:
- the first one conteins a list of items (EList) and each has a name (a
string).
- the second model references exactly one of these elements by its name
and adds aditional parameters
The sencond model must be independent from the first for distribution,
but the first (the "master" model) integrates the second one.
What I want for the second "stand-alone" model (Editor) is representing
the name as a string in a text box property, that's fine with the
generated code. But when used inside the "master model" (in another
Editor) I would like to have a different visual representstion (a
combo-cox) offering all available names only.
My question: How can I change the UI representation of such an element
that is of type string to be a combo-box and where I can control its
choices?</pre>

In the generated property descriptor, you'll want to specialize its
getChoiceOfValues method. When that returns a non-null collection
of values, the properties view will produce a drop down with exactly
those choices. This should give you the idea:<br>

control which instances are available as choices when editing
a property in the properties view?</span></a><br>

Ps.: I am not exactly sure if this question belongs here, please guide
me in the right diretion, if not.

Oh - should it really be that simple... I'll try that. I thought the UI
representation is more coupled...
Thanks Ed, if you don't hear again in this thread you made my day! :-)
