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
documentation.
