WIDGET COMMAND
       The following subcommands are possible for combobox widgets:

       pathName current ?newIndex?
              If newIndex is supplied, sets the combobox value to the element
              at position newIndex in the list of -values.  Otherwise, returns
              the index of the current value in the list of -values or -1 if
              the current value does not appear in the list.

       pathName get
              Returns the current value of the combobox.

       pathName set value
              Sets the value of the combobox to value.

       The combobox widget also supports the following ttk::entry widget
       subcommands (see ttk::entry(n) for details):

              bbox                  delete               icursor
              index                 insert               selection
              xview

       The combobox widget also supports the following generic ttk::widget
       widget subcommands (see ttk::widget(n) for details):

              cget                  configure            identify
              instate               state


VIRTUAL EVENTS
       The combobox widget generates a <<ComboboxSelected>> virtual event when
       the user selects an element from the list of values.  If the selection
       action unposts the listbox, this event is delivered after the listbox
       is unposted.
