Click/hover interaction events on track data

[cukelarter]

Hi! I read the User Interaction documentation and was curious to see if there were any plans or workarounds to enable on-click or hover interactions with track data? For example, in the UCSC and other genome browsers you are able to click on portions of a track to bring up more information about that specific region, ie Ensemble id, rsid, coordinates, or even custom track fields. I've attached a basic example of the type of display I'm thinking of:

Hi @cukelarter, thanks for asking question!

I think you are finding for "tooltip" (http://gosling-lang.org/docs/reference#tooltip). Any specified data in this property will appear in the tooltip upon hovering.

For instance, you can specify the following lines of code from the "Mark Displacement" example you provided

which will display the following tooltip upon hovering.

thanks for pointing this out and providing an example, I was able to get it working! :)
