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(3tk) for
       details):

              bbox                  delete               icursor
              index                 insert               selection
              xview

       The  combobox  widget  also  supports  the  following  generic  ttk::widget   widget   subcommands   (see
       ttk::widget(3tk) 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.
