Description

The combo widget consists of a single-line text entry field and a drop-down list. The drop-down list is displayed when the user clicks on a small arrow button to the right of the entry field. Instead of a combo widget with non-editable entry field, the use of the optionMenu is recommended.

This widget is deprecated since GTK+ 2.4 .

Programmers are advised to use comboEntry instead.
