No. You can also try to catch "insert-text" signal if "key-press-event"
somehow does not suite your needs. But in ideal case you should use
GtkSpinButton instead of GtkEntry to enter numbers. It filters out
everything but numbers. The only downside is that you have to specify
the range of values (however it could be an advantage too).
