tkerror (n)

SYNOPSIS

tkerror message

DESCRIPTION

Note: as of Tk 4.1 the tkerror command has been renamed to bgerror because the event loop (which is what usually invokes it) is now part of Tcl. For backward compatibility the bgerror provided by the current Tk version still tries to call tkerror 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 bgerror instead of tkerror because that support for the old name might vanish in the near future. If that call fails, bgerror 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 bgerror instead of tkerror. Documentation for bgerror is available as part of Tcl's documentation.

'\" '\" .AP type name in/out ?indent? '\" Start paragraph describing an argument to a library procedure. '\" type is type of argument (int, etc.), in/out is either "in", "out", '\" or "in/out" to describe whether procedure reads or modifies arg, '\" and indent is equivalent to second arg of .IP (shouldn't ever be '\" needed; use .AS below instead) '\" '\" .AS ?type? ?name? '\" Give maximum sizes of arguments for setting tab stops. Type and '\" name are examples of largest possible arguments that will be passed '\" to .AP later. If args are omitted, default tab stops are used. '\" '\" .BS '\" Start box enclosure. From here until next .BE, everything will be '\" enclosed in one large box. '\" '\" .BE '\" End of box enclosure.

The first argument is ignored and used for recording '\" the version when the .VS was added, so that the sidebars can be '\" found and removed when they reach a certain age. If another argument '\" is present, then a line break is forced before starting the sidebar. '\" '\" .VE '\" End of vertical sidebar. '\" '\" .DS '\" Begin an indented unfilled display.
