I'm new to IntelliJ after being an eclipse user for +10 years. Through working with eclipse I'm used to the behaviour that when I move my mouse over a variable/class/method/constant ... I get a little popup which shows me related information such as api/signature etc.
By migrating to IntelliJ I read that there is a similar feature in place which used to be enabled in the idea.properties by auto.show.quick.doc=true. And in newer versions through settings File | Settings | Editor | General
I followed the instructions regarding this feature and yet it doesn't work as I would expect.
Simple example when I hover over java.util.Objects.isNull I get the following "quick documentation":
Which is not very help full. If I click here on the icon on the upper right corner "Open as Tool Window". The javadoc for the method is show as well as I would have used the shortcut CTRL + P.
I have this issue not only with base java but with any framework even though the javadoc is available.
I'm a bit confused if I simply misunderstand on how the feature works. May you please give advice on this. Thanks in advanced!
