Remarks

The view is designed to display a scene, which is composed by the merged view and displayed document content. The first visible point of the scene is controlled by the ViewportOrigin property. The device point to which the viewport origin is mapped is accessible from the WindowOrigin property.

All NView derivates share the following set of important features:

The selection contains the current set of manipulated document nodes. It is accessible from the Selection property.
