Bug 111163

Description BenH 2005-09-29 19:40:16 EDT

Currently when Ctl is held while hovering the mouse over a (method or type) 
code symbol, a hyperlink is shown for the symbol linking to that symbols 
source. This a very valuable and frequently used navigation tool.

However, it suffers from a limitation when the symbol is an interface type 
(which it very often is in large systems), that the user is often wishing to 
reach the implementation code, not the interface the hyperlink points to. 

I would like to propose an extension action (assigned to a combo like Ctl-Shift-
MouseHover) that when pointed to an interface type, initiates a search for 
implementors and displays a drop-down pop-up menu of hyperlinks beneath the 
type symbol in the editor. These hyperlinks would work for types or for 
constituent methods.

givent that there is already "find implementors" code in Eclipse, the change is 
mainly about integrating that function with the hover-hyperlink mechanism for 
navigation, for greater efficiency and convenience.
