OK, good. I've only just spotted your previous assorted questions mail. 

To get the list of parents, you can't use this:

    obj = self
    while obj.respond_to?(:parent)
      obj = obj.parent
      STDERR.puts("P: #{obj.class} #{obj.object_id}")
    end

Because QtRuby depends on using method_missing() to trap ruby method calls, 
and divert them to the Smoke library. And so respond_to? will always be 
false. Instead do something like this:

    obj = self.parent
    while !obj.nil?
        STDERR.puts("P: #{obj.class} #{obj.object_id}")
        obj = obj.parent
    end

Gives this output:

focusin lang:spoed_pcode PalgaEdit Qt::Widget
P: Qt::Widget 404978152
P: Qt::WidgetStack 404812828
P: GoToCellDialog 403224788

Well, I have this in my docs for QTabWidget:

virtual void addTab ( QWidget * child, const QString & label )
virtual void addTab ( QWidget * child, const QIconSet & iconset, const QString 
& label )
virtual void addTab ( QWidget * child, QTab * tab )

I still haven't fixed the GC problem with PalgaEdit fields - I'll have another 
try this week.
