...CascadeButtons
XmVACASCADEBUTTON actually specifies CascadeButtonGadgets as children of the MenuBar, but you need not worry about the implications of this for now (see Section 5.3).

...colour
In order to illustrate the list example with a non-trivial and vaguely interesting application we actually use some Xlib colour routines. These have not yet been formally addressed (see Chapter 17). However, the use of colour routines here are not too difficult to comprehend and basically resort to the list callback list_cbk() setting an appropriate XmNbackground  resource value. The reader is urged to concentrate on the List creation and usage matters in this example.
