Hi,
I want to contribute a command to the context menu of en existing editor
(GMF-based Ecore Diagram editor). In Juno it worked well but since
Kepler I have the problem that the HandledMenuItem is contributed but it
is not enabled. Thus, no handler is called. My fragment.e4xmi looks like
this:
<?xml version="1.0" encoding="ASCII"?>
<fragment:ModelFragments xmi:version="2.0"

</fragments>
<fragments xsi:type="fragment:StringModelFragment"

accessibilityPhrase=""

<children xsi:type="menu:HandledMenuItem"

iconURI="platform:/plugin/myplugin.ecoretools.additions/icons/EclassModified.png"
command="_S2HosGCJEeK-fpTrs2yrzw"/>
</elements>
</fragments>
</fragment:ModelFragments>
And my handler looks like this:
public class ModifyFillColorHandler {
private EcoreDiagramEditor editor;
@CanExecute
public boolean checkEcoreDiagramEditor(@Active MPart activePart){
CompatibilityEditor compatibilityEditor = (CompatibilityEditor)
activePart.getObject();
IEditorPart editor = compatibilityEditor.getEditor();
if(editor instanceof EcoreDiagramEditor){
this.editor = (EcoreDiagramEditor) editor;
return true;
}
return false;
}
@Execute
public void fillColorsOfEClasses(){
final Diagram diagram = editor.getDiagram();
TransactionalEditingDomain editingDomain = editor.getEditingDomain();
RecordingCommand command = new RecordingCommand(editingDomain) {
@Override
protected void doExecute() {
@SuppressWarnings("unchecked")
EList<View> visibleChildren = diagram.getVisibleChildren();
for (View child : visibleChildren) {
if(child instanceof Node){
Node node = (Node) child;
if(node.getElement() instanceof EClassifier){
FillStyle fillStyle = (FillStyle)
node.getStyle(NotationPackage.Literals.FILL_STYLE);
// white
fillStyle.setFillColor(16777215);
}
}
}
}
};
editingDomain.getCommandStack().execute(command);
}
}
Any ideas how and where to debug this? How can I determine why the
handler isn't invoked? Any hints?
best regards,
Jan
