1. 窗口的绑定

Step1：导入头文件

#ifndef __APPLE__
#  include "HalconCpp.h"
#else
#  ifndef HC_LARGE_IMAGES
#    include <HALCONCpp/HalconCpp.h>
#  else
#    include <HALCONCppxl/HalconCpp.h>
#  endif
#endif

Step2：声明一个全局的控制变量（HTuple类型）

HTuple WindowHandle;//control variables

Step3：在窗口构造函数中绑定Halcon窗口于控件

    //窗口绑定设置
    Hlong windID = (Hlong)this->ui->gV_image->winId();//绑定控件与halcon窗口
    //OpenWindow(0,0,ui->gV_image->width(),ui->gV_image->height(),0,"","",&WindowHandle);
    OpenWindow(0,0,ui->gV_image->width(),ui->gV_image->height(),windID,"visible","",&WindowHandle);//创建一个窗体ui
    SetPart(WindowHandle,0,0,2748,3664);//1944 2592
    SetDraw(WindowHandle,"margin");
    SetLineWidth(WindowHandle,1);
    SetColor(WindowHandle,"red");

注意：如果没绑定，则Halcon窗口是弹出的，而不是嵌入在控件中的

• 绑定好的：
• 未绑定的：

至此，窗口的绑定工作已完成。

2. 图片显示

void MainWindow::on_pB_Open_clicked()
{
    //
    HTuple FileNameModel;
    HObject halconImage;
    QString path = QFileDialog::getOpenFileName(this,"Select Image","","(*.png *.jpg)");
    if(path == "") return;
    SetDraw(WindowHandle,"margin");
    SetLineWidth(WindowHandle,1);
    SetColor(WindowHandle,"blue");
    FileNameModel = HTuple(path.toLatin1().data());
    ReadImage(&halconImage,FileNameModel);
    DispObj(halconImage,WindowHandle);
}
