How to add an item to system menu of GtkWindow

["Sreenidhi BG" <sreenidhi_bg rediffmail com>]

Hello All,

How can I add an item, say a help or info/About dialog box to the window system menu. The system menu i get on clicking the left top most icon of the gtk window. I want to add another entry to the list of maximize, minimize, restore, close menu items.

Regards,
Sreenidhi,
