Can you specify the No. of chars before SourceView Completion window is displayed?

All,

  I have implemented word completion with GtkSourceView, but I cannot find a
simple way to prevent the provider and proposals from popping up until 3 (or
more) characters are typed? Is there an easier way to adjust this rather than
counting chars with an iter from every begins_word and blocking the display of
the completion window until the desired number of characters have been typed?
