Must be one of left, center, or right. [-height height] Specifies the height of the pop-down listbox, in rows. [-postcommand postCommand] A Tcl script to evaluate immediately before displaying the listbox. The -postcommand script may specify the -values to display. [-state state] One of normal, readonly, or disabled. In the readonly state, the value may not be edited directly, and the user can only select one of the -values from the dropdown list. In the normal state, the text field is directly editable. In the disabled state, no interaction is possible.

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):

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.
