설명
컨트롤에 대해 자식 컨트롤의 크기 조정/표시/숨기기 및 자식 컨트롤 추가/제거 등의 변경 작업을 수행하려면 컨트롤에서 자식 컨트롤의 레이아웃을 지정해야 합니다. LayoutEventArgs는 변경된 자식 컨트롤 및 자식 컨트롤의 영향 받는 속성을 지정합니다. 예를 들어, 마지막 레이아웃 작업 이후에 컨트롤이 표시할 수 있게 되었으면 Visible 속성이 영향을 받습니다.
PerformLayout 메서드가 호출되었을 때 지정된 값이 없으면 AffectedControl 및 AffectedProperty 속성이 Null 참조(Visual Basic의 경우 Nothing)로 설정됩니다.
이벤트 처리에 대한 자세한 내용은 이벤트 사용을 참조하십시오.
예제
다음 코드 예제에서는 AffectedProperty 및 AffectedControl 속성을 LayoutEventHandler 인수로 사용하여 Windows Form 및 컨트롤의 다양한 속성 변경에 따라 Windows Form 및 컨트롤의 크기를 조정합니다.
