50. 둥근 직사각형 그리기 (drawRoundedRect)

drawRoundedRect Class는 모서리가 둥근 직사각형을 그릴 때 사용합니다.

drawRoundedRect() 에 x, y, width, height, x-radius, y-radius의 순서로 숫자를 입력합니다.

50-2 설명

x-radius, y-radius 가 0, 0인 경우 직사각형이 되고, width, height의 절반인 경우 원(또는 타원)이 됩니다.

50-5 설명

drawRect() 예제에서와 마찬가지로 QBrush() 와 setBrush()를 이용해서 둥근 직사각형의 채우기 패턴을 설정할 수 있습니다.
