Comentarios

No se puede mover, cambiar el tamaño o girar un objeto de modo que su ubicación de pantalla resultante estaría completamente fuera de las coordenadas de su contenedor y no se puede acceder al teclado o al mouse. Por ejemplo, cuando una ventana de nivel superior se mueve completamente fuera de la pantalla o un objeto secundario se mueve fuera de los límites de la ventanilla del contenedor. En estos casos, el objeto se coloca lo más cerca posible de las coordenadas de pantalla solicitadas con las coordenadas superior o izquierda invalidada para estar dentro de los límites del contenedor.
