Listbox with varying bkgd and frgd colors from row to row

[DrA10101]

Hi,

I would like to use a listbox with varying background and foreground colors from row to row. Can it be done?

Thanks in advance. All help is appreciated.

sure, i guess the easiest way to do this is to make your own proc that automaticly alters the colours for you.

Yes, use Hugelist:

And then:
listbox .lb -alternate gray

There is some rudimentary support for this with the listbox widget. Check out the listbox itemconfigure operation, and the various attributes that you can set on a per-item basis. However, this isn't particularly robust, especially if you're updating the contents of the listbox frequently.

In addition to the Hugelist megawidget that ulis mentioned, there are some other extensions that you might consider. The tablelist megawidget is actually a mutli-column listbox, with several nice features including column headers and integrating sorting ability. You can find out more about it on the Tcl'ers Wiki (

Another extension that's getting a lot of attention is the TkTreeCtrl. Although it is intended primarily for hierarchical, tree-style display, it can also present information in a "flat" format. It has a very attractive display, but I've found it quite difficult to use in practice. I'd like to see its API simplified so that it's a lot easier to use in simple cases. But you can find out more about it at
