Thank you Rikke and Jeff.
It worked, I simply followed steps in FAQ as suggested by Jeff.
I appreciate the help by both of you. It is great thing about free
software/linux community that you get all help you need!!
Thanks once again.

4.6 How do I get a pointer to a widget in another window?
You need to keep track of pointers to all your toplevel windows.
For simple applications you can just use global variables to store
these
pointers.
For more complicated applications you can use the
gtk_object_set_data() and
related functions to store a pointer to one window inside another
window.
For example, if you want to create a dialog which needs to access
widgets in
the main window you can do this:
dialog = create_dialog1 (); /* Call the function generated by
Glade. */
gtk_object_set_data (GTK_OBJECT (dialog), "main_window",
main_window);
Then when you need to access the main window from within the dialog
code,
you can do this:
main_window = gtk_object_get_data (GTK_OBJECT (dialog),
"main_window");
NOTE: You need to be careful to ensure that the pointer is always
valid.
If the window being pointed to is destroyed, make sure you no longer
use the
pointer to it or your application may crash.
