Squiggle lines on-demand

Hi Kasper,

The way adornments work is that as a view is going to render a line, it asks for any tags over that line's range that would trigger an adornment to be rendered. If you set up a collection tagger (look for CollectionTagger in the samples) you can simply add/remove tagged ranges to that when your validation is done, like: After that code executes, it should trigger SyntaxEditor to render those lines again since you are indicating that the visuals changed.

I'm sorry, but would it be possible for you to provide me with just a bit more details on how to do this? The code sample you have provided doesn't make much sense to me out of context, and I'm not sure where to look for the CollectionTagger. As far as I can tell, you only use it in the IntraTextNoteTagger sample, and while that sample is kinda what I need, I would like to use the built-in squiggle instead of creating one myself.

What I really want to know, is what I should call/do, once my validation is done and I'm ready to add and remove squiggles. I imagine that the easiest way would be to remove them all each time a validation is done and then re-add the ones I still need, but perhaps I'm wrong there. Either way, I would really appreciate a more detailed suggestion on how to do this :)

Hi Kasper,

Take a look at the AdornmentsSquigglesIntro QuickStart as that shows you how to use our built-in squiggle adornments (you effectively just return tags that implement ISquiggleTag). That sample uses a custom tagger that inherits TaggerBase<ISquiggleTag> but in your case you'd want to use a CollectionTagger<ISquiggleTag> instead per what I described above.

When validation is done, I'd probably recommend doing the code snippet in my preview post to clear and re-add them all in a single batch.

Hi,

>Take a look at the AdornmentsSquigglesIntro QuickStart as that shows you how to use our built-in squiggle adornments (you effectively just return tags that implement ISquiggleTag).

Yes, but the difference, as I see it, is that the information about what to underline comes from within the class and not from the outside. I'm still not sure how to add "tags" from outside the SyntaxEditor-space, which was also a part of my previous question. I now have a CodeValidationIssueTagger, which inherits CollectionTagger<ISquiggleTag>, but how do I, from my main window, get access to it and add information about what to underline? I have looked into the GetService() method on the Language, but no matter what I do, I can't seem to get an object out that allows me to add stuff to it. So I guess what I really need to know, is how to access AND supply information to the tagger from the outside, which in this situation is my main window, where all the interesting stuff is happening :)

Edit: Okay, judging from the IntraTextNoteTagger demo, I'm supposed to use the Properties collection on the Document, to get my tagger and not the GetService() method on the Language. That wasn't very clear to me, since it's being added with the RegisterService() method :). I guess I just got one step closer!

Edit 2: Yes, once I had access to the CollectionTagger instance from my main window, and realized that there was now actually nothing left for my own Tagger implementation to do, it seems to work!!

I'm glad you got it working. Yes, there is a tagger provider on the language that will create a new tagger instance for each document instance. That's why you are able to retrieve a document-specific tagger from its properties.

Hi Pieter,

The MainControl's code in the AdornmentsIntraTextNotes QuickStart shows how you can retrieve a tagger from the Document Properties.  You'd do that if you are trying to access the tagger to add/remove tags.  The parameter to GetTags can be null.
