[Glade-users] changing text being typed into entry field

[ashats at hotmail.com (Arthur Shats)]

I have an entry field created in Glade. In my Python code when I type into that field, I want allow only 
alphanumeric characters and make them all capital while typing.
What I have so far is this:
 
def init(wtree) :
  myField = wtree.get_widget('entryField') 
  myField.connect('insert_text', on_entryField_insert_text)
 
on_entryField_insert_text(entry, text, text_length, user_data=None) :
  for char in text[:text_length] :
    if (char.isalnum() == False) :
      entry.emit_stip_by_name('insert_text')
 
  pass
 
The above will only allow typing alpha-numeric characters. How do I modify the code so it would make the 
input all capital letters while typing?
Thanks much.
Arthur.
