예제
다음 코드 예제를 사용 하는 사용자 지정 컨트롤을 만드는 방법을 보여 줍니다 합니다 DrawTabPage 및 DrawTabItem 메서드를 두 개의 탭을 사용 하 여 기본 탭 컨트롤을 그립니다.

설명
합니다 TabRenderer 클래스의 집합을 제공 static 운영 체제의 현재 비주얼 스타일을 사용 하 여 tab 컨트롤을 렌더링 하는 방법입니다. 컨트롤 렌더링이란 컨트롤의 사용자 인터페이스를 그리는 것을 말합니다. 현재 비주얼 스타일의 모양이 있어야 하는 사용자 지정 컨트롤을 그리는 경우에 유용 합니다. 사용 하는 tab 컨트롤을 그리려면 합니다 DrawTabPage 페이지, 그리고 사용 하는 메서드는 DrawTabItem 각 탭을 그리는 방법.
운영 체제에서 비주얼 스타일을 사용 하 고 애플리케이션 창의 클라이언트 영역에 비주얼 스타일을 적용 하는 경우이 클래스의 메서드는 현재 비주얼 스타일을 사용 하 여 tab 컨트롤을 그립니다. 이 클래스의 속성과 메서드를 throw 하는 고, 그렇지는 InvalidOperationException합니다. 이 클래스의 멤버를 사용할 수 있는지 여부를 확인 하려면 값을 확인 합니다 IsSupported 속성입니다.
이 클래스의 함수를 래핑하는 System.Windows.Forms.VisualStyles.VisualStyleRenderer 에서 노출 한 요소 중 하나에 설정 된는 System.Windows.Forms.VisualStyles.VisualStyleElement.Tab 클래스입니다. 자세한 내용은 비주얼 스타일을 사용하여 컨트롤 렌더링을 참조하세요.
