Adornment layers in relation to token taggers

Posted 12 years ago by Nick Beer - National Instruments

Version: 11.1.0545

Hello -

I'm having trouble getting an adornment layer behind the text background layer (this is the layer token taggers use, correct?)

I'm registering my adornment like this:

private static AdornmentLayerDefinition _layerDefinition =
    new AdornmentLayerDefinition("CurrentLine",
        new ordering(AdornmentLayerDefinitions.TextBackground.Key, 
            OrderPlacement.Before));

Even though I'm specifying the layer should be before (or should it be after? I've tried both...) the text background layer, my adornment still draws on top of the text background layer.

Am I doing something wrong?

Thanks -

Nick

Actually - I should note that I have two adornment managers. If I disable one of them, I'm able to place the other behind the text background layer. (I also found out that it should be 'After' and not 'Before').

I found this post that seems to indicate there could be a bug in the orderings when you have multiple adornment layers. Is it possible that's what I'm running into? Can you think of a workaround? I've tried ordering the adornments against the built in layers, but as soon as I have two adornment layers, I can't get one behind the text background layer.

Thanks -

Hi Nick,

Yes I think that's the bug you're running into. I'd recommend doing what was posted in that other thread, where you specify all the known layers that your layers come after. As an instance, we do this for our Text Background layer:

textBackground = new AdornmentLayerDefinition("Text Background",
    new Ordering[] { 
        new Ordering(AdornmentLayerDefinitions.Highlight.Key, OrderPlacement.After),
        new Ordering(AdornmentLayerDefinitions.Selection.Key, OrderPlacement.After),
        new Ordering(AdornmentLayerDefinitions.CollapsedRegion.Key, OrderPlacement.After),
        new Ordering(AdornmentLayerDefinitions.Squiggle.Key, OrderPlacement.After),
        new Ordering(AdornmentLayerDefinitions.TextForeground.Key, OrderPlacement.After),
        new Ordering(AdornmentLayerDefinitions.Caret.Key, OrderPlacement.After),
    });

If you do that sort of thing for your adornment layers, it should work around the issue until it is fixed.

I've just gotten back to this, and your suggestion worked perfectly. Thank you!

Hi Nick,

We've updated our algorithms for orderable sorting so that it works properly, even with a large number of items. This change will be in the next 2012.2 maintenance release.

The latest build of this product (v24.1.1) was released 2 months ago, which was after the last post in this thread.
