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 docu-
mentation.
