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