## Detailed Description

A text entry field with a dropdown list.

A combo is a compound widget which crosses a text entry area and a pull down list. It may allow text entry or it may just allow list values depending on the settings.

Access members allow altering of the widget components.

Deprecated:
  Use the ComboBox widget instead.
