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. 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.
