class PASCALIMPLEMENTATION TComboBoxEx : public TCustomComboBoxEx
TComboBoxEx represents a combo box that supports extended combo box features such as images on the list entries. Add TComboBoxEx to a form when you want to include a combo box that uses the images in an image list or when you want to control how far the items in the drop-down list are indented. TComboBoxEx provides greater support of items than the TComboBox control, but omits certain features as well (owner-drawn items, sorting of list items, and so on).
