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):

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

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.
