       The  class  name  for a ttk::combobox is TCombobox.  The ttk::combobox uses the entry and listbox widgets
       internally.  The listbox frame has a class name of ComboboxPopdownFrame.

       Dynamic states: disabled, focus, pressed, readonly.

       TCombobox styling options configurable with ttk::style are:

       -arrowcolorcolor-arrowsizeamount-backgroundcolor-bordercolorcolor-darkcolorcolor-focusfillcolor-foregroundcolor-fieldbackgroundcolor
              Can only be changed when using non-native and non-graphical themes.
       -insertcolorcolor-insertwidthamount-lightcolorcolor-paddingpadding-placeholderforegroundcolor-postoffsetpadding-selectbackgroundcolor
              Text entry select background.
       -selectforegroundcolor
              Text entry select foreground.

       The ttk::combobox popdown listbox cannot be configured using ttk::style  nor  via  the  widget  configure
       command.  The listbox can be configured using the option database.

       option add *TCombobox*Listbox.background color

       option add *TCombobox*Listbox.foreground color
       option add *TCombobox*Listbox.selectBackground color
       option add *TCombobox*Listbox.selectForeground color

       To configure a specific listbox (subject to future change):
              set popdown [ttk::combobox::PopdownWindow .mycombobox]
              $popdown.f.l configure -font fontComboboxPopdownFrame styling options configurable with ttk::style are:

       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.

       In  addition  to  the  standard cget, configure, identifyelement, instate, state and style commands (see
       ttk::widget), combobox widgets support the following additional commands:

       pathNamecurrent ?newIndex?
              If newIndex is supplied, sets the combobox value to the element at position newIndex in  the  list
              of  -values (in addition to integers, the end index is supported and indicates the last element of
              the list, moreover the same simple interpretation as for the command stringindex  is  supported,
              with  simple integer index arithmetic and indexing relative to end).  Otherwise, returns the index
              of the current value in the list of -values or {} if the current value  does  not  appear  in  the
              list.

       pathNameget
              Returns the current value of the combobox.

       pathNamesetvalue
              Sets the value of the combobox to value.

       The combobox widget also supports the following ttk::entry widget commands:
