示例1: _Draw
void SSkinButton::_Draw(IRenderTarget *pRT, LPCRECT prcDraw, DWORD dwState,BYTE byAlpha)
{
CRect rcDraw = *prcDraw;
rcDraw.DeflateRect(1, 1);
CAutoRefPtr<IRegion> rgnClip;
if(m_nCornerRadius>2)
{
GETRENDERFACTORY->CreateRegion(&rgnClip);
//the last two params of CreateRoundRectRgn are width and height of ellipse, thus we should multiple corner radius by 2.
HRGN hRgn = ::CreateRoundRectRgn(prcDraw->left,prcDraw->top,prcDraw->right+1,prcDraw->bottom+1,m_nCornerRadius*2,m_nCornerRadius*2);
rgnClip->SetRgn(hRgn);
