通过在视图类里添加上述代码完成画一个篮球场

void CLanqiuchangView::OnDraw(CDC* pDC)
{
	CLanqiuchangDoc* pDoc = GetDocument();
	ASSERT_VALID(pDoc);


CBrush brush1(RGB(180,150,50)); 
CBrush *pBrush1=pDC->SelectObject(&brush1); 
/*CPen mypen1(PS_SOLID,5,RGB(0,0,255)); 
CPen *pOldPen=pDC->SelectObject(&mypen1); 
pDC->SelectObject(pOldPen);*/ 

pDC->Rectangle(20,100,1000,625);//大的框架 

CPen mypen(PS_SOLID,5,RGB(255,255,255)); 
CPen *pOldPen=pDC->SelectObject(&mypen);//设置新的画笔 
pDC->Ellipse(447,300,572,425);//中心圆形 
pDC->MoveTo(510,100); 
pDC->LineTo(510,625);//中线 
//pDC->SelectObject(pOldPen);//取消画笔（恢复原来的画笔） 
pDC->Arc(-246,125,286,600,20,600,20,125);//三分线
