Question

请问如何用MFC绘制一个任意三角形，谢谢

元程序画三角形时，第一边必须为垂直边，修改程序使其能画任意三角形
/画三角形
void CPainterView::DrawTriangle(CDC * pDC,RECT rect)
{
pDC->MoveTo(rect.left,rect.top);
pDC->LineTo(rect.right,(rect.top+rect.bottom)/2);
pDC->LineTo(rect.left,rect.bottom);
pDC->LineTo(rect.left,rect.top);
}

//绘制三角形
void CPainterView::OnDrawTriangle()
{
// TODO: Add your command handler code here
DrawType=new BYTE;
*DrawType=TRIANGLE;
}

Answer 1

void CPainterView::OnDrawTriangle()
{
// TODO: Add your command handler code here
DrawType=new BYTE;
*DrawType=TRIANGLE;
}
