예제

다음 코드 예제에서는 Region 둥근 단추를 만들어 속성을 사용 하는 방법을 보여 줍니다.The following code example demonstrates how to use the Region property by creating a round button. 예제를 실행 하려면 라는 단추를 포함 하는 폼에 다음 코드를 붙여넣습니다 roundButton .To run the example, paste the following code in a form containing a button called roundButton. 이 예에서는 Paint 이벤트가 예제에 정의 된 이벤트 처리기에 연결 되어 있어야 합니다.This example requires that the Paint event is connected to the event handler defined in the example.

   // This method will change the square button to a circular button by 
   // creating a new circle-shaped GraphicsPath object and setting it 
   // to the RoundButton objects region.

설명

창 영역은 운영 체제에서 그리기를 허용 하는 창 내의 픽셀 컬렉션입니다.The window region is a collection of pixels within the window where the operating system permits drawing. 운영 체제는 창 영역 밖에 있는 창의 일부를 표시 하지 않습니다.The operating system does not display any portion of a window that lies outside of the window region. 컨트롤 영역의 좌표는 컨트롤의 클라이언트 영역이 아니라 컨트롤의 왼쪽 위 모퉁이를 기준으로 합니다.The coordinates of a control's region are relative to the upper-left corner of the control, not the client area of the control.
