| Overlay icons for validation [message #423852] |

Hello!
I would like to create overlay icons for the EMF providers that change
depending on the current validation status. To perform the validation in
ItemProviderAdapter.overlayImage(Object, Object) seems a little too
expensive. I don´t want to include the status in the model either.
Best way seems to extend the notifyChanged method and to store the
status in a map for singleton adapters.
Any other approaches?
Thanks,
Kristian

Thanks Mario and Ed for your advice!
Here some snippets for those who want to achieve the same (based on the
generated RCP):
Editor::createPages:
labelDecorator = new MyLabelDecorator();
viewer.setLabelProvider(new DecoratingLabelProvider(new
AdapterFactoryLabelProvider(adapterFactory), labelDecorator ));
Editor::updateProblemIndication:
labelDecorator.setDiagnostics(diagnostic);
In MyLabelDecorator (implements ILabelDecorator):
public void setDiagnostics(Diagnostic diagnostic)
{
Map<Object, Integer> oldSeverityMap = severityMap;
severityMap = new HashMap<Object, Integer>();
processDiagnostic(diagnostic, severityMap);
notifyViewer(oldSeverityMap, severityMap);
}
private void notifyViewer(Map<Object, Integer> oldSeverityMap,
Map<Object, Integer> newSeverityMap)
{
List<Object> changedObjects = new ArrayList<Object>();
changedObjects.addAll(oldSeverityMap.keySet());
changedObjects.addAll(newSeverityMap.keySet());
fireLabelEvent(new LabelProviderChangedEvent(this,
changedObjects.toArray()));
}
private ComposedImage decorateSeverity(Image image, Integer severity)
{
List<Object> images = new ArrayList<Object>(2);
images.add(image);
if (severity == Diagnostic.WARNING)
images.add(X3DModelEditPlugin.INSTANCE.getImage("full/ovr16/warning_co "));
else
images.add(X3DModelEditPlugin.INSTANCE.getImage("full/ovr16/error_co "));
ComposedImage ci = new ComposedImage(images){
@Override
public List<Point> getDrawPoints(Size size)
{
List<Point> results = new ArrayList<Point>();
results.add(new Point());
Point overlay = new Point();
overlay.x = 0;
overlay.y = 7;
results.add(overlay);
return results;
}};
return ci;
}
Have fun!
Kristian

Kristian,
That's very cool. Maybe we should provide something like this directly
in the framework. If you open a bugzilla enhancement request with this
as the contribution, I'll definitely look into it. It would make my
demos better! Thanks for sharing!!
