.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.
