  Called whenever text is inserted into the text buffer.
  

• virtual void on_insert_pixbuf (TextIter &pos, Gdk::Pixbuf &pixbuf)

  Called when a pixbuf image is inserted into the buffer.
  

• virtual void on_insert_child_anchor (TextIter &pos, TextChildAnchor &anchor)

  Called when a child anchor is inserted into the buffer.
  

• virtual void on_delete_range (TextIter &start, TextIter &end)

  Called when contents of the buffer in the range start to end are removed.
  

• virtual void on_changed ()

  Called when the contents of the buffer are changed by an insertion or deletion action.
  

• virtual void on_modified_changed ()

  Called when the buffer has been modified since the last time it was saved.
