How to detect mouse hover over a component to trigger actions

Hi every one,

React Studio really powerful, I can handle so complicated web project so easy with RS, thank RS team very much !

My project are work perfect now with RS code. But I need to improve a little to make User Experience better.

I do not know how to add some action to RS code when user hover mouse over a specific component to change it state. Does any one have experience with this case ?

Thank you !
