Hy,
I am looking for a possibility to catch the error in my TCL/TKapplication:
The task is to controll a display, therefor I have the Display Name and 
it cookie.
Using the system command "xauth add <display> . <cookie>" and toplevel 
.dsp -screen <display>  I have access to the display.

If the display closes (xserver shutdown) it would be help ful to catch 
this event, do do also some closings.
What I see so far from the source code, this is exit is hard coded.

Any idee....

regards
