tkerror(n) Tk Built-In Commands tkerror(n)

NAME
       tkerror - Command invoked to process background errors

SYNOPSIS
       ttkkeerrrroorr message



DESCRIPTION
       Note:  as  of  Tk  4.1  the ttkkeerrrroorr command has been renamed to bbggeerrrroorr
       because the event loop (which is what usually invokes it) is  now  part
       of Tcl.  For backward compatibility the bbggeerrrroorr provided by the current
       Tk version still tries to call ttkkeerrrroorr 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 bbggeerrrroorr  instead
       of  ttkkeerrrroorr  because  that support for the old name might vanish in the
       near future. If that call fails, bbggeerrrroorr 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  bbggeerrrroorr  instead  of
       ttkkeerrrroorr.  Documentation for bbggeerrrroorr is available as part of Tcl's docu-
       mentation.
