Need help on Mouse clicks on Tree Item.

[Simith Nambiar <simith indts com>]

Hi All,
              I'am creating an application for displaying a Buddy List, as
in Yahoo Messenger or MSN Messenger.
I could successfully create a Buddy List and Groups for Display, but i do
not know how to enhance it with features like:

1 .) When i Right click on any of the Buddy, i would like to show a list of
operations like, 
         Send Email to John
         Call  John
         Send Instant Message etc.

                                                 |   Send E-mail        |
 
+----------------------------+
                                                 |    Call John            |
                                                 |
---------------------------+
                                                 |    Send IM             |
 
+----------------------------+
                                       John  
                                         /|\
 
I---------------------------------Mouse Right clicked on John which is a
GtkTreeItem Widget.


 All i understand is i have to register for a CLICKED Event , but do not
know how to proceed from there on showing the menu, above described.
 I would appreciate any help or hints on how to go about this.
 
 Cheers.
