Hello Stoyan,

I would like to modify the behavior of the overview object.

Currently, we used it to navigate in the diagram and it works fine.
The rectangle in the overview that represents the part of the diagram that the user can see is the part I would like to change.

In the best case I would love to be able to draw this rectangle, the same way as a selection rectangle. the user clic, hold + drag and draw the selection rectangle which will then, after a mouse release, update the diagramView.

But as the Viewport property of the overview is internal, I cannot override it in any way in an extended class...

So im kinda out of idea.

Is it possible ? can you help me ?

Thanks
Amaury
