How to make javaDoc in IntelliJ IDEA smart as Eclipse?

Question

By checking How to see JavaDoc in IntelliJ IDEA? , I can enable JavaDoc popup whenever I hover a mouse on an java type.

However, there are several problems about the popup window: 1) It can not disappear when I move over my mouse. 2) It has a fixed window size instead of adjusting itself automatically based on the content.

In Eclipse, there are no such problems. Is there any solution ?

Thanks in advance!

Answer 1

The closest to Eclipse will be Ctrl+Button2 Click (Scroll click)

Hope JetBrains add that feature Eclipse-like soon.
