Hi Everyone!

Im workin on a WinForms application, in which I have to perform multiple different tasks on images.

I made a WinForms where I can load images and I can display these imaes in a PictureBoxIpl. This PictureBoxIpl is made by the opencvsharps Userinterface.dll.
The application is working nicely, I can load the images.
I want to achieve that I can mark squares in this PictureBoxIpl with the mouse, but I dont know how to "track"
the mouse movements inside PictureBoxIpl.
If you know, please tell me which are the methods to perform this operation.
I thought it would be something like this :

wImage.OnMouseCallback += delegate(MouseEvent ev, int x, int y, MouseEvent flags)

but in this PictureBoxIpl I cant find the PictureBoxIpl.OnMouseCallback method.
