SYNOPSIS

       tkerror message

DESCRIPTION

       Note:  as of Tk 4.1 the tkerror command has been renamed to bgerror because the event loop (which is what
       usually invokes it) is now part of Tcl.  For backward compatibility the bgerror provided by  the  current
       Tk  version still tries to call tkerror if there is one (or an auto loadable one), so old script defining
       that error handler should still work, but you should anyhow modify your scripts to use bgerror instead of
       tkerror  because  that  support  for  the  old  name might vanish in the near future. If that call fails,
       bgerror posts a dialog showing the error and offering to see the stack trace to the  user.  If  you  want
       your  own  error  management  you should directly override bgerror instead of tkerror.  Documentation for
       bgerror is available as part of Tcl's documentation.
