Unregister Adornment Service

Posted 12 years ago by Actipro Software Support - Cleveland, OH, USA

Hi Nick,

In your AdornmentManager, you can probably do this to remove them:

protected override void OnClosed() {
    // Remove any remaining adornments
    this.AdornmentLayer.RemoveAllAdornments();
}

Hmm... I guess that's the problem. When I call UnregisterService, the OnClosed handler in my AdornmentManager is not called. Do you expect that it should be?

Hi Nick,

You'd probably need to get the IAdornmentManager for the ITextViews you have open and call Close() on each one before unregistering the service.

The language service doesn't hold any ties to SyntaxEditors or views so it doesn't know how to have a CloseAll() sort of concept, because it wouldn't know which views are still active.

OK, thanks. I've done that and have been able to unregister and remove my adornments. However, now I'm unable to turn them on again at a later time. It seems that the AdornmentManagerProvider must be registered in the constructor of the SyntaxLanguage?

Anyhow, I've worked around it by just setting a flag in the AdornmentManager. It seems that it would be preferable to simply register and unregister these services, but it doesn't appear you support that for now.

Hi Nick,

Correct, the manager provider doesn't know if it's been registered on a language and what views may be using those languages. You could just call the provider.GetAdornmentManager(view) method on any view that should receive an adornment manager again. I believe that will register it.

But if you will be toggling things, then it may be preferable to just flag whether adornments should be displayed or not and leave the adornment managers in place.
