Hello,
I would like to display (or not) some parts of my editor given the value of a semantic element.
Ex : Imagine an EClass Definition with two EAttributes Type and Unit.
If Type equals String I don't want to display the field Unit in my editor.
To do so, I extended the XXXPropertiesEditionPartImpl and overidden the createControls method in order to provide the behavior I want by modifying the CompositionSequence of the composer.
It works quite well except that the editor is not dynamically updated when I change the value of my semantic element. I need to display another file or close the editor and open it again to see the semantic change reflected in my editor (because createControls is called again).
Now I would like to do it dynamically, so I assume I need to override the createXXXEMFComboViewer (in my case) in order to add a ISelectionChangedListener which will update the editor during the call of selectionChanged. Am I right? Is it the right way to do it?
The problem is I can't figure out how to update the editor. Do you have any idea?
Have a good day,
Regards,
Xavier Seignard

Hello,
Do dynamically update the view, you need to change the
"updateSemanticModel" method of the component using the composer and the
composition sequence. For example : this code change the visibility of
the first widget each time the value of my combo changes :
((CompositePropertiesEditionPart)editingPart).getComposer(). getCompositionSequence().getSubSteps().get(0).getSubSteps(). get(0).switchVisibilty();((CompositePropertiesEditionPart)ed itingPart).refresh();
initPart(partKey, 0, this.semanticObject);
