thanks for your answer!  Interesting, I didn't know XCloseDown.

But most of the time, it's not what I want.  I normally close all
applications by hand after I finished using them and before logout, and
only if I forgot one, I want to get a warning message instead of the
logout when trying to exit openbox, so that I can take care of what I
had forgotten.  Especially, I don't want anything to be killed
automatically.

I massaged the script I had found under
http://daemon-notes.com/articles/desktop/openbox/configs a bit to get
this work.  If any running X app is found (except for panels etc.), the
script just exits with a message.  Here is the result, for those who are
interested:

--8<---------------cut here---------------start------------->8---
#!/usr/bin/env bash

# derived from a script found at
# from http://daemon-notes.com/articles/desktop/openbox/configs

EXIT_COMMAND="openbox --exit"
ACTION=$1

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/root/bin

NUM_DISPLAYS=`xvinfo | grep 'screen #' | wc -l`
CUR_DISPLAY=0

while [ $CUR_DISPLAY -lt $NUM_DISPLAYS ]; do
	export DISPLAY=":0.$CUR_DISPLAY"
		CLIENTS=""
		WINDOWS=`xprop -root _NET_CLIENT_LIST | awk -F# '{ print $2; }' | tr -d ","`
		for ID in $WINDOWS; do
			WINDOW_TYPE=`xprop -id $ID _NET_WM_WINDOW_TYPE`
			TYPE_NOT_SET=`echo $WINDOW_TYPE | grep "not found" | wc -l`
			TYPE_NORMAL=`echo $WINDOW_TYPE | grep _NET_WM_WINDOW_TYPE_NORMAL | wc -l`
			if [ $TYPE_NOT_SET -eq 1 -o $TYPE_NORMAL -eq 1 ]; then
				CLIENTS="$CLIENTS $ID"
			fi
		done

		if [ -n "$CLIENTS" ]; then
                    xmessage -center "Please close all clients first"
                    exit;
		fi

	        CUR_DISPLAY=`expr $CUR_DISPLAY + 1`
done

export DISPLAY=":0.0"

case $ACTION in
-r)
	sudo reboot
	;;
-h)
	sudo halt -p
	;;

	$EXIT_COMMAND
	;;
