Forward to UI for comment. You can use Ctrl+Shift+Space to get the parameter hints. We don't plan to show this in an additional hover. I am reopening this, as control-shift space just shows the entire signature of the method and does so without Javadoc. Often when looking at method calls with many parameters, I'd need to know what a particular parameter's purpose is by reading its Javadoc. Presently I have to counting the number of parameters until I reach the one of interest, then I have to hover over the method name and count again. This doesn't necessarily have to be performed with a mouse hover--though I'd prefer it--a keyboard shortcut would be okay. Incidentally, IntelliJ uses control-P to do to this. We don't want to add a hover. The fix for bug 385642 will probably address your request as you could open the Javadoc view via key binding (if it is not yet open). *** This bug has been marked as a duplicate of bug 385642 *** Kind of a workaround/similar feature is: foo(34, bar1, <cursor>bar2) press ctrl-space This shows the method signature above with the formal parameter corresponding to bar2 highlighted. (in juno at least, not sure above 3.8) PS: Not sure how this is a duplicate of #385642 ... It would be a great workaround since usually the parameter names are self-documenting, but there's no highlighting of the parameter (bar2 in your example) in Indigo. |
Suppose I have the following code: void foo(int i) {} void bar() { foo(1); } If I hover over the 1, I would like to see "int i" as I do if I hover over "foo". I know this can conflict with showing the Javadocs of methods or fields in the parameter such as how presently Eclipse shows on hover the Javadoc for random() below: void bar() { foo(random()); } Perhaps there could be a hover modifier key to override this and a precedence order to determine which Javadoc is displayed in this case.
