Detecting cursor leaving control

How can I detect when the mousecursor leaves a control?
I do some highligting in an ownerdrawn Outline control, and I need to know when the mouse leaves the control, so I can remove the highlighting. (It's a standard mouseover-effect). Im using Delphi 1.0

You need to override the control and create a component that decends from TOutLine and here is the message to be triggered...
private
  procedure CMMouseEnter(var msg:TMessage); message CM_MOUSEENTER;
  procedure CMMouseLeave(var msg: TMessage); message CM_MOUSELEAVE;

{...}
procedure MyComponent.CMMouseEnter(var msg:TMessage);
begin
    inherited;
    {respond to mouse enter}
end;

procedure MyComponent.CMMouseLeave(var msg: TMessage);
begin
    inherited;
    {respond to mouse leave}
end;
