SetMouseCallback not working

[claudeHasler]

Summary of your issue

Im trying to select a ROI by mouse input. I wish to get the pixel coordinates by means of a mouseCallback, however the mouseCallback never seems to be called. Other callbacks such as trackbar seems to work just fine.

Environment

Visual Studio 2017 WPF

Example code:

    public void getMouseClickCoordinates(MouseEvent e, int x, int y, MouseEvent f)
    {
        System.Windows.MessageBox.Show("im a callback");
    }

    public void trackbarCallback(int pos, object userdata)
    {
        System.Windows.MessageBox.Show("im a trackbarcallback");
    }


    public MainWindow()
    {
        InitializeComponent();
    }

   int bla = 5;

    private void Button_Click(object sender, RoutedEventArgs e)
    {


        Mat mat;
        mat = Cv2.ImRead("C:\\Users\\Master\\Desktop\\img.png");
        Cv2.NamedWindow("myWindow");


        
        
        Cv2.CreateTrackbar("myTrackbar", "myWindow", ref bla, 0, new 
        CvTrackbarCallback2(trackbarCallback));

        Cv2.SetMouseCallback("myWindow", new CvMouseCallback(getMouseClickCoordinates));

        Cv2.ImShow("myWindow", mat);
        Cv2.WaitKey(2000);


        

    }
