Access to layer inside HoverTooltip

[sronveaux]

Hi team,

This is more a question than a real issue I think... this one could be for @fschmenger as he's the man behind the excellent Generalized Feature Hover functionality:

I have a case where the same source (a collection of Feature objects) is assigned to multiple layers each having a different styling function and each showing up different data inside an overlay. The data to be shown is associated with the layers, not the features as those layers are dynamic and created on-the-fly. They are not part of the config file.
To avoid creating multiple HoverTooltip components, I could easily extract the data I want to display depending on the hovered layer. However, there currently is no way to know which layer is hovered inside a MapOverlay, only the feature.

In the code, the HoverController receives feature-layer pairs inside its displayTooltip function but forwards only the feature to the MapOverlay afterwards. Would you mind if I open a PR where the layer is forwarded next to the feature to the MapOverlay or is there another way and I missed something ?

Thanks in advance,
Sébastien

Hi Sebastien, I had no time to dig very deep but I couldn`t think of a way to obtain the layer easily and I also see no downside from forwarding it to the MapOverlay.

Hi Felix, thanks for the fast reply, that's perfect, I'll create a small PR shortly to address this...

Cheers,
Sébastien
