Question

怎样画一个矩形并填充颜色？？？我很菜的

Answer 1

pDC->Rectangle(CRect(m_BeginSelectPoint,m_EndSelectPoint));

Answer 2

HDC dc = ::GetDC(GetSafeHwnd());
LOGBRUSH logbr;
memset(&logbr , 0 , sizeof(LOGBRUSH));
logbr.lbColor = RGB(58,110,165);
logbr.lbStyle = BS_SOLID;
HBRUSH hBrush = CreateBrushIndirect(&logbr);
HBRUSH oldbr = (HBRUSH)SelectObject(dc , hBrush);
         RECT rt = {10,10,100,100};
FillRect(dc , &rt , hBrush);
         SelectObject(dc , oldbr);
         DeleteObject(hBrush);
         ReleaseDC( GetSafeHwnd() , dc);

Answer 3

CDC *pDC = GetDC();
pDC->SelectObject(CreateSolidBrush(0xff)); // 填充为红色
pDC->Rectangle(5, 5, 50, 50); // 按照指定的矩形做图
ReleaseDC(pDC);

Answer 4

CDC *pDC =GetDC();CRgn Rgn;
Rgn.CreatePolygonRgn(points,m_EdgePoints.GetSize(),WINDING);pDC->Polyline(points,m_EdgePoints.GetSize());
pDC->FillRgn(&Rgn,&brush);其中的points 是一个数组,存储你要画的矩形或多边形的各个点的值,
m_EdgePoints是CArray类型的储存的也是矩形或多边形的各个点的值,实际
points和m_EdgePoints里面存储的是相同的值
