[Glade-users] blocking some input in entry field

[ashats at hotmail.com (Arthur Shats)]

Yes, the link you sent me with the use of emit_stop_by_name does work. Thanks John.
However, I had to remove insert_text handler from Glade and added my own (from the example) manually with 
connect call as well.
Don't understand why adding the handler in Glade gives me run time error (there is no problems with other 
handlers that I added in Glade, like on_myField_activate handler). I am afraid I may be doing something wrong 
and it would come back to bite me later.
If anybody have an explanation on what the trace "TypeError: <lambda>() takes at most 2 arguments (4 given)" 
mean and how to get rid of it, please let me know.
Thanks again,
Arthur.

Thanks John.
Using GtkSpinButton is not going to work for me (my field takes in IP address, not just plain numbers), but 
I'll try the link that you mentioned.
 
I am doing the code in Python and use GladeX to generate python code from Glade xml, so my _insert_handler 
looks like this:
 
def on_myField_insert_text(widget, data, wtree) :
   print "in insert_text"
   pass

But when I execute, I get error:
 
TypeError: <lambda>() takes at most 2 arguments (4 given)

Maybe GladeX has a bug and it generated the function incorrectly, so do you know what kind of arguments 
_insert_text should have?
Thanks.
