How to bind an event in Tix combo box?

[dudeja.rajat at gmail.com]

Hi,

I'm a newbie and created a new combo box with Tix.
The combo box is filled with the required items.

I've used Tkinter's listbox and used the <ListboxSelect> event and
bind that with a callback.
Now, I want to do the same stuff with the Tix combo box.

Please suggest how can I do the same in Tix combo box.

Thanks and regards,
Rajat
