설명

합니다 ButtonRenderer 클래스의 집합을 제공 static 단추 컨트롤을 렌더링 하는 데 사용할 수 있는 방법입니다. 컨트롤 렌더링이란 컨트롤의 사용자 인터페이스를 그리는 것을 말합니다. 단추를 그릴 중 하나를 사용 합니다 DrawButton 메서드. 이러한 메서드는 다양 한 텍스트 그리기 또는 단추 이미지와 같은 옵션을 제공합니다.

운영 체제에서 비주얼 스타일을 사용 하 고 현재 애플리케이션에 비주얼 스타일을 적용 하는 경우 DrawButton 현재 비주얼 스타일을 사용 하 여 단추를 그립니다. 그렇지 않으면 DrawButton 클래식 Windows 스타일을 사용 하 여 단추를 그립니다. 운영 체제의 현재 비주얼 스타일 설정을 자동으로 일치 해야 하는 사용자 지정 컨트롤을 그리는 경우에 유용 합니다.

이 클래스의 함수를 래핑하는 System.Windows.Forms.VisualStyles.VisualStyleRenderer 에서 노출 한 요소 중 하나에 설정 된는 System.Windows.Forms.VisualStyles.VisualStyleElement.Button.PushButton 클래스입니다. 자세한 내용은 비주얼 스타일을 사용하여 컨트롤 렌더링을 참조하세요.

속성

RenderMatchingApplicationState

렌더러에서 애플리케이션 상태를 사용하여 렌더링 스타일을 결정하는지 여부를 나타내는 값을 가져오거나 설정합니다.
