A ttk::combobox combines a text field with a pop-down list of values; the user may select
the value of the text field from among the values in the list.

-class -cursor -takefocus
-style

See the ttk_widget manual entry for details on the standard options.

WIDGET-SPECIFIC OPTIONS
[-exportselection exportSelection] Boolean value. If set, the widget selection is linked
to the X selection. [-justify justify] Specifies how the text is aligned within the wid-
get. 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 immedi-
ately 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. [-textvariable textVariable] Specifies the name of a
global variable whose value is linked to the widget value. Whenever the variable changes
value the widget value is updated, and vice versa. [-values values] Specifies the list of
values to display in the drop-down listbox. [-width width] Specifies an integer value
indicating the desired width of the entry window, in average-size characters of the wid-
get's font.

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(n) for details): bbox delete icursor
index insert selection xview The combobox widget also sup-
ports the following generic ttk::widget widget subcommands (see ttk::widget(n) 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.
