Ein hilsbereiter Kollege vom delphiarea forum hat mir weiter geholfen:
Delphi-Quellcode:
type
TNoShadowHintWindow = class(THintWindow)
protected
procedure CreateParams(var Params: TCreateParams); override;
end;
procedure TNoShadowHintWindow.CreateParams(var Params: TCreateParams);
const
CS_DROPSHADOW = $00020000;
begin
inherited CreateParams(Params);
Params.WindowClass.Style := Params.WindowClass.Style and not CS_DROPSHADOW;
end;
initialization
HintWindowClass := TNoShadowHintWindow;
end.
