// File: flexcombobox.h
//
// Desc: Implements a combo box control similar to Windows combo box.
//       CFlexComboBox is derived from CFlexWnd.  It is used by the page
//       for player list and genre list.  When the combo box is open,
//       CFlexComboBox uses a CFlexListBox for the list window.
