GtkEditable::insert_text
void insert_text(string text_string, int position); 
    
     insert_text()  is the simplest
     way of putting text into an editable widget. 
     GtkText has an alternative method, 
     insert() , which gives greater
     control over the appearance of the text, amongst other things.
    
    
      This method does not support internationalization under win32.  Use
      insert() .
     
 
    
     The insert_text()  method also
     causes the signal of the same name to be emitted.
