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.
