WIDGET COMMAND <\/a> <\/h2>\n

The following subcommands are possible for combobox widgets:
pathName<\/i> current<\/b> ?newIndex<\/i>?<\/p>\n

If newIndex<\/i> is supplied, sets the combobox value to the element at position newIndex<\/i> in the list of \u2212values<\/b> (in addition to integers, the end<\/b> index is supported and indicates the last element of the list). Otherwise, returns the index of the current value in the list of \u2212values<\/b> or \u22121<\/b> if the current value does not appear in the list.<\/p>\n

pathName<\/i> get<\/b><\/p>\n

Returns the current value of the combobox.<\/p>\n

pathName<\/i> set<\/b> value<\/i><\/p>\n

Sets the value of the combobox to value<\/i>.<\/p>\n

The combobox widget also supports the following ttk::entry<\/b> widget subcommands (see ttk::entry(n)<\/i> for details):<\/p>\n\n\n\n
<\/td>\n\n

bbox<\/b><\/p>\n<\/td>\n

The combobox widget also supports the following generic ttk::widget<\/b> widget subcommands (see ttk::widget(n)<\/i> for details):<\/p>\n

cget configure identify<\/b><\/p>\n\n\n
<\/td>\n\n

\n

 <\/td>\n<\/tr>\n<\/table>\n

VIRTUAL EVENTS <\/a> <\/h2>\n

The combobox widget generates a <><\/b> 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.<\/p>\n

STYLING OPTIONS <\/a> <\/h2>\n
