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. +.SH KEYWORDS +background error, reporting +'\" Local Variables: +'\" mode: nroff +'\" End: |
