	// last added widget when the grid is in a horizontal orientation, and
	// at the bottom of the last added widget if the grid is in a vertial
	// orientation.  Using a grid in this manner works similar to a gtk.Box,

	// and columns to span over.

	// position of 1 (starting at the same vertical position as the button),

	// same vertical position as the entry).

	// This example also demonstrates how not every area of the grid must
	// contain a widget.  In particular, the area to the right of the label
	// and the right of spin button have contain no widgets.
