Your original approach was right: set_events() will reset the event mask (as 
opposed to add_events() which will not), although a better approach may be to 
call m_TreeView->set_events(m_TreeView->get_events() & 
~Gdk::BUTTON_PRESS_MASK).

However, did you call set_events() before the widget was realised?  It won't 
work if you do not.
