Here's a note on '''wm withdraw''' from George Petasis in the comp.lang.tcl newsgroup:

I wouldn't advise you to use 
"wm withdraw ." on the "." window. Under some window managers
(especially under unix...) this will prevent dialogs that have as
parent the "." (like error messages) to not show up and block
your app. Better to use something like:

 wm geometry . 1x1+0+0
 wm overrideredirect . 1
 wm transient .

You can even send it out of the visible part of the screen, like
 wm geometry . 1x1+3000+3000

But in any way do not withdraw it :-)
----
'''wm protocol''': Use
        wm protocol <window> WM_DELETE_WINDOW {#}
to prevent your window from closing when the [[X]] button is clicked.  More on this subject appears under the title "[Catching window managed events]".

Could someone address monochrome vs multicolor icons and how to use
the appropriate wm command to achieve the difference?

[Eric Brunel] writes, on news:comp.lang.tcl ,

Since I just spent half an hour to figure out how this works, I thought
someone might be interested. The exact syntax is:
 wm iconbitmap <window> <icoFileName>
and not:
 wm iconbitmap <window> @<icoFileName>
(the "regular" bitmap files required the "@" in front of them and the manual is a tad unclear on this point...).
----
'''wm iconwindow''' may not work immediately. [Joe English] wrote in [the comp.lang.tcl newsgroup]:
''You probably just need to unmap and remap the top-level window, so the window manager will notice the changes:''
 % wm withdraw .
 % wm state . normal
