将Qt的label设置成Halcon的窗口，并显示

h文件中：

public:

HTuple hv_WindowHandle;

Hlong windID；

 

cpp文件中

 windID = (Hlong)this->ui->label->winId();

OpenWindow(0,0,ui->label->width(),ui->label->height(),windID,"visible","",hv_WindowHandle);

 

SetDraw(hv_WindowHandle,"margin");

SetLineWidth(hv_WindowHandle,2);

SetColor(hv_WindowHandle,"red");

SetSystem("filename_encoding","utf8");

 

void DisplayImage(HObject image, HTuple windHandle)

{

          HTuple  img_width , img_height;

         GetImageSize(image,&img_width,&img_height);

         SetPart(windHandle,0,0,img_height- 1 , img_width - 1);

         DispObj(image,windHandle);

}
