[Glade-users] Where is the input callback method in glade?

[ramirez.ferdinand at yahoo.com (Ferdinand Ramirez)]

Thanks. I tried something similar with GtkTextBuffer and it worked, but I cannot modify the text, only block 
it or let it through. If I modify it, and insert the modified text into the buffer from within the callback, 
I end up in an infinite loop.

Is there another way you know, using GtkTextView perhaps?

Thanks,
-Ferdinand
