hi 

i have doubt in how to get data entered in to text entry widget.
i am using glade and c.
in my interface.c entry pointer is stored as 

GLADE_HOOKUP_OBJECT (window_ssnew, entry_name, "entry_name"); 

how to refer the entry_name (text entry widget name) in callbacks.c

using lookup_widget how can i do that, and after calling the function
how to get the text entered in to the entry widget (entry_name);

thanks;

vasu.
