    Description

    This command is available since GTK+ 2.4. The comboEntry 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 comboEntry widget with non-editable entry field, the use of the optionMenu is recommended.
