[TRUCO DELPHI] Verifica si el Raton soporta caracteristica de Rueda / Wheel.
delphi
function MouseWheelExists: Boolean; begin Result := GetSystemMetrics(SM_MOUSEWHEELPRESENT) <> 0; end;
Ejemplo de Uso:
delphi
procedure TForm1.Button1Click(Sender: TObject); begin if MouseWheelExists then ShowMessage('Tiene ruedita..'); end;
Saludos!
