.SH NAME
tkerror \- Command invoked to process background errors
.SH SYNOPSIS
\fBtkerror \fImessage\fR
.BE
.SH DESCRIPTION
.PP
Note: as of Tk 4.1 the \fBtkerror\fR command has been renamed to
\fBbgerror\fR because the event loop (which is what usually invokes
it) is now part of Tcl. For backward compatibility
the \fBbgerror\fR provided by the current Tk version still
tries to call \fBtkerror\fR 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 \fBbgerror\fR instead
of \fBtkerror\fR because that support for the old name might vanish
in the near future. If that call fails, \fBbgerror\fR
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 \fBbgerror\fR instead of \fBtkerror\fR.
Documentation for \fBbgerror\fR is available as part of Tcl's
documentation.
