This is not quite correct.  The Pmw.ComboBox has an Pmw.EntryField
component, named 'entryfield', which has a Tkinter.Entry component,
named 'entry'. So, more correctly:
   xxx.component('entryfield').component('entry').configure(width = 4)

Since this is long winded, you can use Pmw's component options:
   xxx.configure(entryfield_entry_width = 4)

Or even shorter, since the Tkinter.Entry sub-sub-component of the
Pmw.ComboBox has an alias named 'entry':
   xxx.configure(entry_width = 4)

Component options (and aliases) can also be used during construction:
   xxx = Pmw.ComboBox(entry_width = 4)

For more detail, see the Pmw documentation.
