You /// must assure that your HALCON window as well as your /// ROIController instance are registered to the HWndCtrl instance. /// You can use any kind of implementation for your graphical user /// interface. To create ROIs you must pass the GUI events to the /// ROIController. To add a new ROI shape, for example a circular /// interactive ROI, you must create a new class ROICircular, which /// inherits from ROI. The button for circular objects must then forward /// the request to the ROIController, similar to the way it is done for /// Rectangle1 and Rectangle2. /// </summary> public class InteractiveForm : System.Windows.Forms.Form{private System.Windows.Forms.GroupBox groupBox1;
