tkerror(3tk) Tk Built-In Commands tkerror(3tk)

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 be-
cause 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 load-
able one), so old script defining that error handler should still work,
but you should anyhow modify your scripts to use bgerror instead of tk-
error 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 tker-
ror. Documentation for bgerror is available as part of Tcl's documen-
tation.
