Examples of ViewportModel

com.google.collide.client.editor.ViewportModel
The model for the editor's viewport. This model also listens for events that affect the viewport, and adjusts the bounds accordingly. For example, it listens as a scroll listener and shifts the viewport when the user scrolls. The lifecycle of this class is tied to the current document in the editor. If the document is replaced, a new instance of this class is used for the new document.
