tkerror - Command invoked to process background errors


tkerror message


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.
