Show Javadoc when hovering over deprecated method call [message #1766316]

Hi,

I often browse code that is calling a deprecated method, which gives a compiler warning. When I hover over such a call, I get the "xxx is deprecated" warning hover. Quite often, the called method's javadoc has indications on which method to use instead, but I can only get there via F3, or with the Javadoc view, which I never use. I'd like to see the javadoc on hover over just as I see it for non-deprecated calls. Any ideas or tips? Maybe add support to 'cycle' through hovers?

Hi

Me too. If an editor has a default hover that clarifies a usage, it is a pain if a squiggle replaces the hover with something more important that the underlying hover is need to understand. Worse in the debugger perspective, an evaluated value may usurp the hover. It is a pain having to change perspectives just to get a better hover. While the developers may know a magic short cut to get a specific category of hover, users do not. The hover must indicate locally what Fx button to press to access more hover (e.g. F2 for focus). Behind the scenes, there should probably be a stack of potential hovers, from which the default and alternates are displayed lazily. Currently hover code seems hard coded to offer only the 'best' eagerly.

So to make this better, we should either be able to cycle (like with code assist proposal pages) or, hackish, merge all the hovers into one separated by horizontal lines. I have no clue about the technical difficulties of implementing either..
