C/C++ Mode Imenu Problem

C/C++ Mode Imenu Problem

[Thomas D. Dean]

GNU Emacs 23.3.1 (amd64-portbld-freebsd9.0, GTK+ Version 2.24.6) of 
2012-01-07 on P9X79.tddhome

Using CC Mode version 5.31.8

In the C/C++ modes, if the number of items in the imenu is greater than 
imenu-max-items, the displayed menu is grouped with items named

   from ...
   from ...

etc.

In this case, selecting one of the items from the imenu popup does not 
result in a change to current line.  The display remains the same.

Changing imenu-max-items to a value greater than the number of items 
found, all the items are displayed in one menu.

In this case, selecting one of the items from the imenu popup results in 
the current line being changed to the item selected.  The display 
changes to show the selected item.

I found a couple references to this in archives, but, no solution.

I believe this worked in emacs 22.

In this case, pressing <return> rather than using mouse-1 changes the 
current line to the selected item and changes the display to that item.

In the case where imenu-max-items is greater than the number of items in 
the menu, mouse-1 changes the current line to the selected item and 
changes the display to that item.

How can I change this behavior to have mouse-1 select the item in imenu?

	The problem is not linked to C/C++ modes (I've seen it in Python
mode), nor to the number of items in the menu. The problem occurs
whenever the menu is hierachical (which may happen because there are
too many items, or because it was built that way e.g by semantic).

	I too would be interested in a solution. This is the last remaining
issue for me to drop XEmacs in favor of vanilla Emacs.

	Is there a bug tracker somewhere where the issue can be entered /
has already been entered?

	Thanks,

The GNU Emacs bug tracker is here: http://debbugs.gnu.org/.

You can submit a bug report or enhancement request using `M-x report-emacs-bug'.
See  also the Emacs manual: `C-h r g checklist'.

	It seems I cannot comment on the bug and I didn't see anyplace
where I could register (or login for that matter), so if you want to
add the following steps to reproduce:

- emacs -Q
- Execute the following lisp commands (for example in the scratch
buffer):
  - (require 'imenu)
  - (global-set-key [S-mouse-3] 'imenu)
  - (semantic-mode 1)
- Open a C++ file (or type the following in a new C++ file):

==============================8<------------------------------
class foo {
  void a (void) {}
  void b (void) {}
  void c (void) {}
};
------------------------------>8==============================

- Then play with the menu (S-mouse3 + mouse1). It may work for a
short while (0 to 5 times), then it stops going to the target with
mouse1 although it still goes with return.


	Emacs version 23.4.1 on 64 bits ArchLinux.

	Thanks,
		Jerome

	Thanks, I had found the web page but I didn't know that comments
should be mailed. I have added a comment with the steps to reproduce.

	Note that I was able to reproduce the issue on 32 bits and 64 bits
Linux, but not on Windows (with the packages from EmacsW32).

	Thanks,
		Jerome

I think you're saying that mouse-1 on an Imenu menu item does not take you to
the right place (or anywhere at all), whenever the menu is hierarchical (i.e.,
has submenus).

FWIW, I do not see that problem in any GNU Emacs version (20-24) on MS Windows.
Consider filing a bug report, giving a step-by-step recipe that starts from
`emacs -Q'.
