A New tk_messageBox Widget For Tcl/Tk

I've modified the built-in tk_messageBox widget of Tcl/Tk in three ways:

On UNIX systems with a color depth of 4 or more, the icons are shown in color instead of black-and-white.
The message box is centered over the window identified by the -parent option ("." by default). If the parent window doesn't exist or is iconified, the message box is centered in the whole screen.
On an error dialog, the button says "Bummer" instead of "OK", since errors are never ok.

The interface to the new tk_messageBox is exactly the same as the original. You should be able to drop this new module into your existing Tcl/Tk programs without having to change a thing. The code is in a file named msgbox.tcl. Just download it and make is a part of your program, or use it to replace the "msgbox.tcl" file in the standard TCL library (usually located at /usr/local/lib/tk8.X or /usr/lib/tk8.X).

The following table shows a comparison of the old and the new tk_messageBox widgets:
