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 docu-
       mentation.
