Hi,

Is there any way to set a priority list for the combined hover feature? For example, ideally I'd like it to work this way (with no hotkeys):

1. Is there a compilation error? If yes, display "Problem description"
2. Is there source available? If yes, display "Source"
3. Is there a Javadoc? If yes, display "Javadoc"

This order is important because Eclipse will always display the fully-qualified name of a symbol (function prototype, class name, etc) for a "Javadoc" hover. The default priority list is 1,3,2, which makes it impossible to get a "Source" hover without setting a hotkey since there is always a "Javodoc" hover available (even when there is no actual Javadoc!) which takes priority over the "Source" hover.

The description for combined hover says "Tries the hovers in the sequence listed in above table, excluding this hover, and uses the one which fits best for the selected element and the current context." This to me implies that there should be some way of changing the sequence listed in the above table, but I can't seem to accomplish that.

I'm using Indigo Service Release 1.

Is there somewhere I can request this change, or can you point me to the right place in the source to do it myself?

We don't plan to change the combined hover, but you can implement your
own via the 'org.eclipse.jdt.ui.javaEditorTextHovers' extension point.
