예제

다음 코드 예제를 사용 하는 방법을 보여 줍니다는 둥근 단추를 만들어 속성을 합니다 Region . 예제를 실행하려면 라는 단추 roundButton가 포함된 양식에 다음 코드를 붙여넣습니다. 이 예제에서는 Paint 이벤트가 예제에 정의된 이벤트 처리기에 연결되어야 합니다.

설명

창 영역은 운영 체제에서 그리기를 허용하는 창 내의 픽셀 컬렉션입니다. 운영 체제는 창 영역 외부에 있는 창의 일부를 표시하지 않습니다. 컨트롤 영역의 좌표는 컨트롤의 클라이언트 영역이 아니라 컨트롤의 왼쪽 위 모서리를 기준으로 합니다.

참고

지역에 포함된 픽셀의 컬렉션은 연속되지 않을 수 있습니다.
