I've had a look for examples of Qt::ComboBox, and the tictac one creates a 
combo box like this:

		# Create the combo box for deciding who should start
		# and connect its clicked() signals to the buttonClicked() slot
		@whoStarts = Qt::ComboBox.new(self)
		@whoStarts.insertItem('Computer starts')
		@whoStarts.insertItem('Human starts')
		l.addWidget(@whoStarts);

So it doesn't create a seperate Qt::ListBoxItems like you do, but adds the 
list of things directly to the ComboBox with the insertItem() method.

   @combo = Qt::ComboBox.new(false, centralWidget(), "@combo")
   @combo.setGeometry( Qt::Rect.new(20, 59, 105, 33) )
   @combo.insertItem("oranges")

Alternatively, I think Qt::ComboBox.setListBox() resets everything, so you 
might need to do that first rather than last, and it might work.
