画线,打点功能(WinUI提供了极其简单的接口供用户输入控制WinUI画线,打点)

1, WinUI界面开发引擎库对界面画线的支持是非常好的,他接口简单,封装在CWUILine中, 用户仅仅需要调用SetLinePointVector就可对画线进行控件 void CDlgLine01::DrawRect() { vector<POINT> vcPT; POINT pt; pt.x = 100; pt.y = 100; vcPT.push_back(pt); pt.x = 250; pt.y = 100; vcPT.push_back(pt); pt.x = 250; pt.y = 100; vcPT.push_back(pt); pt.x = 250; pt.y = 250; vcPT.push_back(pt); pt.x = 250; pt.y = 250; vcPT.push_back(pt); pt.x = 100; pt.y = 250; vcPT.push_back(pt); pt.x = 100; pt.y = 250; vcPT.push_back(pt); pt.x = 100; pt.y = 100; vcPT.push_back(pt); if (m_pLayLine1) { m_pLayLine1->SetLinePointVector(vcPT); } } 以上为画矩形代码
