Description
Responds to Windows messages sent to the edit control or drop-down list.
ComboWndProc overrides the method in the TCustomCombo class to handle the common processing of Windows messages sent to the edit region or list portion of the combo box. The messages sent when the user presses a key and the TDragMode is set to automatic are an exception.
The Message parameter describes the Windows message. The ComboWnd parameter is the Windows handle for the edit region or list. The ComboProc parameter is a pointer to the default window procedure for the window that received the message.
