This file describes Listbox.patch which alters the standard listbox widget to allow disjoint selections. Listbox.patch is a patch to the original Tk 3.2 sources. The patch alters the following files: tkListbox.c library/tk.tcl library/listbox.tcl doc/listbox.n After applying the patches you will need to do a make install. To get an understanding of the bindings read the man page and look at the class bindings in tk.tcl. The bindings are somewhat arbitrary, though I did try to make them sensible. Your existing programs should not break (I hope :-). If they do, please let me know. Remember, you can undo the patches with patch -R. Please send me mail with any suggestions and problems.
