Using Combo Boxes

A combo box control is a combination of two other controls: a list box and an editor static control.

It serves the same purpose as a list box – it lets the user choose one text item from a scrollable list of text items by clicking the item with the mouse. The edit control, grafted to the top of the list box, provides another selection mechanism, allowing users to type the text of the desired item. If the list box area of the combo box is displayed, the desired item is automatically selected. TComboBox is derived from TListBox and inherits its member functions for modifying, querying, and selecting list items. In addition, TComboBox provides member functions for manipulating the list part of the combo box, which, in some types of combo boxes, can drop down on request.

See EXAMPLES\OWL\OWLAPPS\OWLCMD for a combo box control example.
