The following subcommands are possible for combobox widgets:



  

  
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.

  

  
Returns the current value of the combobox.

  

  
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

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.
