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. The changes are backward compatible, so that
old uses of tkerror should still work, but you should modify
your scripts to use bgerror instead of tkerror.
Documentation for bgerror is available as part of Tcl's
documentation.
