Properties shown in the bottom bar for labels and points, but not for shapes

[LucaMarconato]

🐛 Bug Report

When I add a layer with features and hover it with the mouse over one of the geometrical instances, I expect to see the text description of the currently hovered instance in the bottom bar. This happens correctly for labels and points, but not for shapes.

Related to https://github.com/napari/napari/issues/2866.

💡 Steps to Reproduce

I use these three snippets from the napari example gallery, copy-pasted:

• Add points with features
• Add shapes with features
• Add labels with features

To reproduce the bug, I simply over the mouse over any geometrical instance for the current layer.

Labels (correct)

Points (correct)

Shapes (wrong)

We see shapes (422 109): 1 in the bottom bar, but no reference to "likelihood" nor "class".

💡 Expected Behavior

I expect a text description for the current hovered property to be visible in the bottom bar. This happens for labels and points, but not for shapes, as you can see in the images below.

It is not a bug, it is feature request.

It requires changes in shape layer like in Labels and Points:

https://github.com/napari/napari/blob/c73e9d5ec0864cc9fa727cf7b147ccdd6ab39a03/napari/layers/labels/labels.py#L1548-L1581

and

https://github.com/napari/napari/blob/c73e9d5ec0864cc9fa727cf7b147ccdd6ab39a03/napari/layers/labels/labels.py#L1497-L1505

Maybe we should generalize it somehow to any layer with properties.

It is not a bug, it is feature request.

I mean, if it never worked, for any layer, then yes? But I think it's a very reasonable expectation that if it works for labels and points, it works for Shapes--especially given that we have an example to show it off! So it does feel like a bug. For what it's worth, I didn't realize this didn't work and I recently steered a user into it... 👀 I've not heard back, so maybe they haven't tried it 🤷

The point is it never has worked. Each layer is implemented separately so each layer is a separate feature request. Of course, as @Czaki pointed out, perhaps it means that we should unify the implementations.
