+Three different spin-boxes are displayed below.  \
+You can add characters by pointing, clicking and typing.  \
+The normal Motif editing characters are supported, along with \
+many Emacs bindings.  For example, Backspace and Control-h \
+delete the character to the left of the insertion cursor and \
+Delete and Control-d delete the chararacter to the right of the \
+insertion cursor.  For values that are too large to fit in the \
+window all at once, you can scan through the value by dragging \
+with mouse button2 pressed.  Note that the first spin-box will \
+only permit you to type in integers, and the third selects from \
+a list of Australian cities.
+If your Tk library linked to Ruby doesn't include a 'spinbox' widget, \
+this demo doesn't work. Please use later version of Tk \
+which supports a 'spinbox' widget.
