text entry key press

["neha gupta" <nehaiitd gmail com>]

Hello

I have made an application using gtk. It contains a text entry line.
When I press simple keys they are shown in the text entry but when I
press Control, Shift, Alt etc they are not shown. 

I need to print control, shift and alt keys  also along with normal keys..I tried to find on the net but found no help. 
 In fact, key_press_event signal was mentioned at some places but I cun't make it to work.

Someone plz guide me in this as I am new to gtk programming. I need  it urgently. 

Thanks
