I certainly don't  want to dynamicaly change the event mask (assuming that
there is an individual event mask for EACH widget).   All I want is for the
tree view to be unresponsive to mouse clicks.

What do you mean by "realising" the object ? Do you mean creating the object
?

If so, how can you set the event bit mask for the object before the object
is created - I would get a segmentation fault - attempt to use a NULL
pointer.

If you mean that realising the object is "showing" it, then I set the event
bit mask well before then.

I set the event bit mask with the instruction immediately after creating the
object, you can't get it any earlier than that ? can you ?

    m_TreeView = new Gtk::TreeView();
    m_TreeView->set_events(m_TreeView->get_events() &
~Gdk::BUTTON_PRESS_MASK);
