tkerror - Command invoked to process background errors
|
||
|
|
<H3><A NAME="M3">SYNOPSIS</A></H3>

<B>tkerror </B><I>message</I><BR>

<H3><A NAME="M4">DESCRIPTION</A></H3>
|
||
|
|
Note: as of Tk 4.1 the <B>tkerror</B> command has been renamed to
|
||
|
|
<B><A HREF="../TkCmd/bgerror.htm">bgerror</A></B> because the event loop (which is what usually invokes
|
||
|
|
it) is now part of Tcl. For backward compatibility
|
||
|
|
the <B><A HREF="../TkCmd/bgerror.htm">bgerror</A></B> provided by the current Tk version still
|
||
|
|
tries to call <B>tkerror</B> 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 <B><A HREF="../TkCmd/bgerror.htm">bgerror</A></B> instead
|
||
|
|
of <B>tkerror</B> because that support for the old name might vanish
|
||
|
|
in the near future. If that call fails, <B><A HREF="../TkCmd/bgerror.htm">bgerror</A></B>
|
||
|
|
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 <B><A HREF="../TkCmd/bgerror.htm">bgerror</A></B> instead of <B>tkerror</B>.
|
||
|
|
Documentation for <B><A HREF="../TkCmd/bgerror.htm">bgerror</A></B> is available as part of Tcl's
|
||
|
|
documentation.
