The problem is now solved. i use xlsclients -l to know the windowid and xwit to focus. thanks to you all. erez.

A quick search in debian's archive finds also: tinywm - tiny window manager Seems to actually include three versions, a C version (58 lines), annotated C version (179 lines), and a python version (40 lines). Seems useful mainly as a demonstration. nawm - Non-windowmanager with windowmanager functionality Somewhat similar to xwit. -- Didi = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

It was a focused effort, oh, maybe half an hour long. Most of that time was spent searching for the name of the AC_PATH_XTRA configure macro. is missing a way to find out what window handles are there now. Remember - do not ask the window manager for this information! Run xwininfo and click on the window. How about having xfocus display a list of the handles of all open windows (along with some identifying information such as window title or controlling process ID - for the user to match up with more information using ps's output) when provided with no window handle argument? Like Didi already said, xwininfo can do that too. When done, xfocus will be cool little application! I'm not sure it's worth the trouble of packaging it, but if the need is there I have no objection.

Indeed, but is it needed? xwit exists (for 17 or so years now), together with many other small forgotten utilities from the 90's, many of which can be found in your favourite x.org mirror under contrib/utilities, and in the archive of your favourite linux distro (especially if that's Debian :-) ). -- Didi = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Do consider using one which is either simple or can be configured to be simple enough for your needs. I used for a very long time (until 1-2 years ago) fvwm, which has (among many other features) a module called FvwmCommand, which can be used to send to it commands at runtime. There might be other WMs that have similar features, I don't know. -- Didi = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

I googled for the above and came up with: http://en.wikipedia.org/wiki/Xmonad - a tiling window manager for X-Window, written in Haskell. Makes it possible to manage windows without using a mouse. http://cgi.cse.unsw.edu.au/~dons/blog/2007/05/01 http://cgi.cse.unsw.edu.au/~dons/blog/2007/05/17 Those articles describe the design of the above (written in Haskell, of all languages!).
