# [NAME](#NAME)

tkerror - Command invoked to process background errors

# [SYNOPSIS](#SYNOPSIS)

**tkerror message**

```

```

# [DESCRIPTION](#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. Using the **tkerror** name is deprecated.

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 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.
