turn them off by using the view menu and selecting 'hierarchy view only'
a.

Hi Vladimir,
I'm the developer of the call hierarchy view, so I guess that I'm biased
:-) Anyhow, I'd like to comment.
I don't agree that it's useless. The location part of the view presents
the actual call including the actual parameters used. If your method
doesn't take any parameters, I agree. If you only have one call to a
method, I agree (although it allows you to see the actual details of the
call).
Best regards,
Jesper

Hi Jesper,
No doubt that your work is appreciated. The feature is good, serves a
purpose most of the time, all I am saying is "let's make it better".
Use case:
Suppose that a user invoked Method call hierarchy (MCH) on method A. As
currently implemented a tree of method calls that invoke A in selected scope
is presented. Currently there is no option to select a scope. User should
maybe have an optional scope selection - as in search. Not a priority I
guess.
The details of the features I have in mind.
Feature 1:
Improve the the present functionality by introducing one click on the method
element B in MCH tree. One click takes a user to a specified file location
in java editor. File is opened, if necessary, and specified location (call
to A) is highlighted. If multiple calls are made to A from the selected MCH
tree element B, those calls are somehow indicated as well (highlighting,
arrows pointers from left margin etc)
Feature 2:
Introduce hover. Ctrl + mouse over tree element B (that calls A) shows a
source hover for that method B with indication of call(s) made to A. So
basically replicate feature 1 in a different form i.e. java source hover.
Java source hover as currently implemented in JDT might not be suitable
since the current implementation shows only n first lines of selected
element. The better solution might be presenting source of B in a hover
with a scrollable window - similar to F2 - "make hover sticky" feature of
JDT. Anyhow, the goal is to show the source of B and indicate the context of
each call made to A.
By introducing feature 1 and 2 you eliminate the need for the separate
"Location/Call" panel. Functionality is greatly improved , clutter is
reduced and consistency is kept along with features that user is already
familiar with in JDT.
Any opinions?
Best regrads.

I couldn't agree more on the "make it better" idea :-)

What do you mean by scope in this context? It's possible to set the
limit the search scope on the view menu. Do you have something else in mind?

I see your point in presenting the same information in another way. I
have taken the liberty of creating a bug report
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=38904) on this matter.

i'm Jesper's 'buddy' on the eclipse.org side (the guy who releases Jesper's code to cvs :))
yes, we look at the enhancements and decide if that's the right direction
but it's very good to experiment with different approaches - if anything, it's very easy to revert, right?
cheers

Ok, I see your point (toString() is a good candidate for
OutOfMemoryExceptions :-) ). The way the call hierarchy works now is
more static - the search scope is related to the view and not to the
current use of the action (the type hierarchy doesn't have a search
scope yet, but AFAIK it's in the JDT UI plan).
I don't know if it would be a good idea to add search scope to the
context menu. If the menu item is changed there should at least be a
way to use the currently set search scope). The keyboard shortcut should
at least be kept as it is.
Again, I may be biased, but that's the way I use it (and the way
whomever I have pursuaded to use the thing use it :-) ).

Jesper

No, I'm just a contributor kept on a short leash by my master :-) No
