Hello everyone. I sent the email below to the ECB list since I use ECB with CEDET, but it seems that this is the correct forum.
Does anyone have any thoughts on the request below? Thanks.

Subject: ECB and speedbar

Hello all:
I currently have the ecb directory window displaying speedbar instead of the proprietary ecb directory implementation.
When I open a buffer in the main edit window, I see that the directory window(speedbar) updates the directory path, but does not "recenter" the window on the currently active file. What I find is that I can only display X amount of files in the directory window, given the window size....and if I open a file which is in that directory, but not visible due to the size constraints, I have to manually scroll down and find it.
Is it possible to have this recentering such that the directory will display the newly opened buffer? I hope my request is clear.

Subject: AW: [ECB-list] Tagdefinition window for ecb

AFAIK in GNU Emacs etags.el this function is named find-tag-noselect - do not know if it does some different things but IMO this function has to be used with GNU Emacs... but i think this code is a very good starting point for intergarting such a new ECB-window into ECB - i'm planning to add a contrib-subdirectory to the ECB-directory where such contributions will be added and so shipped with the ECB-releases - with current stable CVS-snap ECB offers already a pretty straightforward API to create new ECB-windows - i have to add a chapter to the manual... and also some code-clearings more - but in general it should be quite usable now... the added ecb-examples.el should be a sufficient starting point for this...

hauke, could you please ajust your code to the new examples-file (only some new macros) and then tell me what are you missing in the ecb-examples.el or what is not explained good enough?!

Betreff: RE: [ECB-list] Tagdefinition window for ecb

Hello Hauke,

Can this code be used for Emacs21.3 as well as XEmacs? I could not
locate any information on find-tag-internal, so I guess that is an
XEmacs only function?

I really like this concept, but it seems I might have to wait see if it
is integrated in ecb by Klaus.

        Ok, after fiddling a lot with this, i came up with a first
working copy for this!

        The following will always show (if found via (find-tag)) the
definition of a tag under cursor in

        an ecb window.

        Tested with XEmacs, ECB 2.31 under Windows XP.
