[Glade-users] How to block some input in GtkEntry field

[Cristobal Navarro]

hello Arthur

the problem with "changed" callback is that the action has already been
done.
look for another event, maybe one that someone would not naturally take for
a textField, for example "key-pressed". i havent tested my self but i think
the solution goes by using an event prior to change the string
best regards
