ILightweightLabelDecorator does not update [message #83342]

Hi !

Does anyone allready use light weight decorators ? I don't succeed to
update them explicitly...

In decorators extensions, I create a light weight decorator with a class
which implements ILightweightLabelDecorator. I just fill in the decorate
method which overlays the image conditionally.

When I do a change in my model which can affect the decoration, I call
PlatformUI.getWorkbench().getDecoratorManager().update("MY_DECORATOR ");
but the decorate method of MyLightweightLabelDecorator is never reach...

What do I do wrong ?

Any idea ?

Emmanuel

Hi Emmanuel,

I haven't played with this interface yet. Have you tried the same thing
with RCP? If you have an example that works with RCP and does not with
RAP, could you please file a bug?

Thanks,
Ralf

Hi !

What I tried could not work because I use
PlatformUI.getWorkbench().getDecoratorManager().update("MY_DECORATOR_ID ");
which can only be used when no class is specified.

It seems that a LabelProviderChangedEvent shoud be fired. But I have no
idea how to fire it... Moreover, I tried to use LabelDecorator rather than
LightweightLabelDecorator but I have exacty the same problem : how to
notify that the decorate method should be execute.
