实现圆角窗口

[见习学术士]

对话框程序，想实现圆角窗口。
自绘了标题栏，如果实现类似QQ那种圆角？

下面是贴图绘制标题栏

	//平铺标题
	pBitmap->LoadImage(CUtilityEx::GetBasePath() + "images\\bgtitle.bmp");
	pBitmap->GetBitmap(&bmpInfo);
	pOldBitmap=(CBitmap*)pDisplayMemDC->SelectObject(pBitmap);
	pDC->BitBlt(m_rtTitle.left, m_rtTitle.top, m_rtTitle.Width(), m_rtTitle.Height(), pDisplayMemDC, 0, 0, SRCCOPY);
	pDisplayMemDC->SelectObject(pOldBitmap);
	pBitmap->DeleteObject();

int SetWindowRgn(

    HWND hWnd,	// handle to window whose window region is to be set
    HRGN hRgn,	// handle to region 
    BOOL bRedraw	// window redraw flag 
   );

C/C++ code
int SetWindowRgn(

HWND hWnd, // handle to window whose window region is to be set
HRGN hRgn, // handle to region
BOOL bRedraw // window redraw flag
);

2楼正解。
在OnSize里面去设置圆角。
楼上说的在OnInitDialog()去设置的话如果这个窗体时可变大变小的，就错了。

如果系统不支持CreateRoundRectRgn函数呢，比如说windows mobile中

[muzizongheng]

CRgn rgn;
rgn.CreateRoundRectRgn(0, 0, 100, 100, 4, 4);

SetWindowRgn(rgn, FALSE);

放到OnInitDialog()函数中就可以了
