TCustomComboBoxEx Class

TCustomComboBoxEx is the base class for combo box components that support extended combo box features such as images on the list entries.

TCustomComboBoxEx = class(TCustomCombo);
class TCustomComboBoxEx : public TCustomCombo;

Use TCustomComboBoxEx as a base class when defining a control that represents a Windows extended combo box (ComboBoxEx). An extended combo box is an edit box with a scrollable list attached to it that provides native support for item images. Users can select an item from the list or type directly into the edit box. Extended combo boxes can present the list as a drop-down list or as a list box that is always visible.

Note: To create a combo box class that does not use the extended combo box features such as images associated with entries, use the TCustomComboBox class instead.
Do not create instances of TCustomComboBoxEx. To put an extended combo box in a form, use a descendant of TCustomComboBoxEx, such as TComboBoxEx
