예제

다음 예제에서는 처리 합니다 Paint 이벤트 및 사용 하 여는 PaintEventArgs 클래스를 폼에 사각형을 그립니다. 합니다 MouseDown 고 MouseUp 처리 되는 사각형의 크기를 결정 합니다. 또한는 Invalidate 다시 그려져 야 하므로 사각형의 영역을 무효화 하는 방법입니다.

설명

Paint 이벤트 컨트롤을 그리면 발생 합니다. A PaintEventArgs 지정 된 Graphics 컨트롤을 그리는 데 및 ClipRectangle 그릴.

이벤트 모델에 대 한 자세한 내용은 이벤트 처리 및 발생합니다.

생성자

PaintEventArgs(Graphics, Rectangle)

지정한 그래픽과 클리핑 사각형을 사용하여 PaintEventArgs 클래스의 새 인스턴스를 초기화합니다.

속성

ClipRectangle	항목을 그릴 사각형을 가져옵니다.
Graphics	그리는 데 사용되는 그래픽을 가져옵니다.

메서드

Dispose()	PaintEventArgs에서 사용하는 모든 리소스를 해제합니다.
Dispose(Boolean)	PaintEventArgs에서 사용하는 관리되지 않는 리소스를 해제하고, 관리되는 리소스를 선택적으로 해제할 수 있습니다.
Equals(Object)	지정된 개체가 현재 개체와 같은지 확인합니다. (다음에서 상속됨 Object)
Finalize()	가비지 컬렉션이 회수하기 전에 개체가 리소스를 해제하고 다른 정리 작업을 수행할 수 있게 합니다.
GetHashCode()	기본 해시 함수로 작동합니다. (다음에서 상속됨 Object)
GetType()	현재 인스턴스의 Type을 가져옵니다. (다음에서 상속됨 Object)
MemberwiseClone()	현재 Object의 단순 복사본을 만듭니다. (다음에서 상속됨 Object)
ToString()	현재 개체를 나타내는 문자열을 반환합니다. (다음에서 상속됨 Object)

명시적 인터페이스 구현

IDeviceContext.GetHdc()	Windows 디바이스 컨텍스트의 핸들을 반환합니다.
IDeviceContext.ReleaseHdc()	Windows 디바이스 컨텍스트의 핸들을 해제합니다.
