[Dialog] 모서리가 둥근 윈도우

그림과 같이 윈도우 모서리를 둥글게 만들고 싶다면

 

다이얼로그를 생성하고  

#define DIALOG_WIDTH 500
#define DIALOG_HEIGHT 360
#define DIALOG_COMPENSATION_WIDTH  7
#define DIALOG_COMPENSATION_HEIGHT  8

 

OnInitDialog함수에서 아래를 적용해서 사용하면 된다.

필자가 아래에 사용한 define은  윈도우 크기를 변경시키고 그리고 border frame을 없앤 경우였기 때문에 보상해주는 값으로 정의했다.  보통 border가 있다면 GetClientRect나 GetRect를 이용해서 윈도우의 크기를 얻을 수 있다.
