A simple example of the use of listbox (modified from the previous example, so that the scrollbar now works--[D. McC]) would be:

 #! /usr/bin/env wish
listbox .lb -selectmode multiple -height 4
 frame .f
 listbox .lb -selectmode multiple -height 4
 scrollbar .sb -command [list .lb yview]
 .lb configure -yscrollcommand [list .sb set]
 .lb insert 0 sample stuff colors red yellow green
 pack .lb .sb -in .f -side left -expand 1 -fill both
 grid .f
 .lb itemconfigure 0 -foreground blue
 .lb itemconfigure 1 -foreground white
 .lb itemconfigure 2 -foreground black
 .lb itemconfigure 3 -foreground red
 .lb itemconfigure 4 -foreground yellow
 .lb itemconfigure 5 -foreground green
[LV]: So, once `.lb` is created, and someone selects one of the entries, then

Often someone asks how to get a listbox to take more than one selection and people recommend they read the above reference page's information on ''-exportselection 0'' .
'''CJU:''' Normally, if you have more than one listbox on the screen, selecting one listbox automatically unselects any previous selections in the all of the others. ''-exportselection 0'' is a way of getting around that at the cost of not being able to export the list element(s) to the X selection. I understand the reasoning for this behavior, but I think the default for ''-exportselection'' should be 0 instead of 1 for the listbox simply due to the confusion it can cause for newcomers of Tk and also the relative rarity of the need to copy from a listbox as opposed to a text or entry widget, for example.

[RS] 2006-12-11 [Mousewheel] is supported by Tk (on Win XP at least), but in a surprising way: [focus] is needed, but can't be applied by clicking into a listbox, even with the -takefocus 1 option. After an explicit
 focus .lb
the widget border is highlighted, and the mousewheel can be used to scroll up and down.
