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. Using the tkerror name is deprecated.


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 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.
