绘制代码;

void CDaocaView::OnDraw(CDC* pDC){	CDaocaDoc* pDoc = GetDocument();	ASSERT_VALID(pDoc);	// TODO: add draw code for native data here	COLORREF DaoChaColor= RGB(0,0,0);	int width = m_rect.Width() ;	int height = m_rect.Height() ;	CPen newpen(PS_SOLID,60,DaoChaColor);	CPen newpen1(PS_SOLID,60,RGB(0,255,255));	CPen *pOldPen = pDC->SelectObject(&newpen);     pDC->MoveTo(m_rect.left,(int)(m_rect.top + height*0.5));	 pDC->LineTo((int)(m_rect.left +width*0.33),(int)(m_rect.top + height*0.5));    	 pDC->MoveTo((int)(m_rect.left +width*0.33),(int)(m_rect.top+height*0.5));	 pDC->LineTo((int)(m_rect.left +width*0.5),(int)(m_rect.top+(height*0.5+width*(sqrt(3))/6)));	 pDC->MoveTo((int)(m_rect.left +width*0.67),(int)(m_rect.top + height*0.5));	 pDC->LineTo((int)(m_rect.left +width),m_rect.top+height*0.5);	m_rect.left=240;	m_rect.right=440;	 pDC->MoveTo(m_rect.left,(int)(m_rect.top + height*0.5));	 pDC->LineTo((int)(m_rect.left +width/3),(int)(m_rect.top + height*0.5));	 pOldPen = pDC->SelectObject(&newpen1);	 pDC->MoveTo((int)(m_rect.left +width/3),(int)(m_rect.top+height*0.5));	 pDC->LineTo((int)(m_rect.left +width*2/3),(int)(m_rect.top+height*0.5));	 pOldPen = pDC->SelectObject(&newpen);	 pDC->MoveTo((int)(m_rect.left +width*2/3),(int)(m_rect.top + height*0.5));	 pDC->LineTo((int)(m_rect.left +width),m_rect.top+height*0.5);	 m_rect.left=470;	 m_rect.right=670; 	 pDC->MoveTo(m_rect.left,(int)(m_rect.top + height*0.5));	 pDC->LineTo((int)(m_rect.left +width/3),(int)(m_rect.top + height*0.5));	 pDC->MoveTo((int)(m_rect.left +width/3),(int)(m_rect.top+height*0.5));	 pDC->LineTo((int)(m_rect.left +width*0.5),(int)(m_rect.top+(height*0.5-width*(sqrt(3))/6)));	 pDC->MoveTo((int)(m_rect.left +width*2/3),(int)(m_rect.top + height*0.5));	 pDC->LineTo((int)(m_rect.left +width),m_rect.top+height*0.5);	 m_rect.left=700;	 m_rect.right=900; 	 pDC->MoveTo(m_rect.left,(int)(m_rect.top + height*0.5));	 pDC->LineTo((int)(m_rect.left +width/3),(int)(m_rect.top + height*0.5));	 pDC->MoveTo((int)(m_rect.left +width/3),(int)(m_rect.top+height*0.5));	 pDC->LineTo((int)(m_rect.left +width/2),(int)(m_rect.top+(height*0.5+width*(sqrt(3))/6)));	 pDC->MoveTo((int)(m_rect.left +width*2/3),(int)(m_rect.top + height*0.5));	 pDC->LineTo((int)(m_rect.left +width),m_rect.top+height*0.5);       	pDC->SetBkMode(TRANSPARENT);	pDC->SelectObject(pOldPen);}

头文件添加一个成员变量:CRect m_rect;

初始化;

CDaocaView::CDaocaView(){	// TODO: add construction code here	m_rect.left=10;	m_rect.top=10;	m_rect.right=210;	m_rect.bottom=210;}

包含<math.h>;

绘制效果如下;

    我也不太了解什么是道岔;可能是指的铁路交叉的地方;
