15 Note: as of Tk 4.1 the tkerror command has been renamed to bgerror
16 because the event loop (which is what usually invokes it) is now part
17 of Tcl. For backward compatibility the bgerror provided by the current
18 Tk version still tries to call tkerror if there is one (or an auto
19 loadable one), so old script defining that error handler should still
20 work, but you should anyhow modify your scripts to use bgerror instead
21 of tkerror because that support for the old name might vanish in the
22 near future. If that call fails, bgerror posts a dialog showing the
23 error and offering to see the stack trace to the user. If you want your
24 own error management you should directly override bgerror instead of
25 tkerror. Documentation for bgerror is available as part of Tcl's docu‐
26 mentation.
