QT+VS2015+Halcon图像简单处理与显示

环境：Win10-x64+VS2015+Qt5.9.7+Halcon12

首先创建一个Qt GUI Application。工程名：myDockWidget。将Halcon12包含目录与库目录文件放到工程目录下：

选择工程属性页，配置halcon环境：

头文件

class myDockWidget : public QMainWindow
{
Q_OBJECT

public:
myDockWidget(QWidget *parent = Q_NULLPTR);

private:

QPushButton *runPushButton;
QLabel *m_qLabel;

HObject mainImage;
HTuple m_hWindowID;
private slots:
void runPushButtonSlot();
void progressPushButtonSlot();
};
