tkerror(3tk) Tk Built-In Commands tkerror(3tk) 





NAME


tkerror - Command invoked to process background errors






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.
