In IntelliJ IDEA, if you type a variable and then hit the period “.” button, you get a list of possible members to choose from. If you press Ctrl+Space, you get a documentation window containing further explanations of each member.
As a learner, I want to make this extended documentation pop-up automatically every time. For example, if I’m programming in Java and I type:
System.
I want the documentation window to pop-up every time I select a member, without having to press Ctrl+Space. If you’ve used Visual Studio to program in C# I think you’ll know what I mean.
Going into File->Settings->Editor->Code Completion and changing the autopopup documentation timers did not help.
Visual Studio 2010 implements intellisense extremely well, in my opinion.
Automatic documentation pop-up was designed to work with Ctrl+Space code completion, otherwise you have to use Ctrl+Q to invoke it.
It is not displayed with the new fully automatic code completion introduced in the latest IntelliJ IDEA version, this behavior is by design.
