# tkerror(3tk)

Command invoked to process background errors

```

```

## NAME

tkerror - Command invoked to process background errors

## 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.
