gtk entry

[srinivas <srinivas comodo com>]

hi; 

   i am developing gui with glade, C. i have some pbm in passing signal
from one callback signal to another callback.
   
     i have a text_entry_activate callback, in which i am checking text
entered or not. if not warning msg will pop up. i am getting this
functionality.

     now i have one more callback button_next_click. i want
functionality like when i press this next button, first it will check
the text entry for entered or not. if entered then the next layout
displayed. if not the same pop up has to display.
 
     now due to glade, widget creation in interface and callbacks in
callbacks.c, i am not getting how to refer the entry widget using
button_next_click. how to create object of entry widget and how can i
pass the signal to text_entry_activate.


thanks;

vasu.
