navigation in overrides/parents of a method

The Qt creator has a very good code completion / code navigation system. However I find one feature that is present is Netbeans from version 6.9 and that is currently missing in Qt Creator: navigation through overrides of a method. Here is how it could work: a dropdown menu could be accessed when the mouse is on a method that has overrides (in context menu, or after clicking on some symbol...). This menu would list all the overrides and enable to go to their declaration or definition (in netbeans this menu appears in the left margin). The same menu could also list the parent method when it exists. This is very useful to navigate in code relying heavily on virtual methods.
