The OnClick and the OnDblClick events occur when the user clicks on the component. The events OnMouseMove, OnMouseDown, and OnMouseUp support the handling of the mouse. See the Delphi (C++ Builder) documentation for more details.

Note, that the OnMouseMove event is internally used to control the interactive operation if the property MouseAction is set to a value other than maNone.
