Kitalpha/viewpoint/viewpointManager

The Viewpoint Manager enables to manage the state of viewpoints used by a project.
Once a viewpoint is installed, in conformance to the Viewpoint Lifecycle, four actions are available in the viewpoint manager: reference, unreference, activate, deactivate.
Note: This management, introduced in [| Kitalpha 1.1.0], differs from the older versions of Kitalpha when the management of viewpoints was at the workspace level and the viewpoint actions were Start and Stop [ 1 ].

Management of viewpoint at the project level

The state of viewpoint is individually managed by project. To know or change the state of a viewpoint for a project:

• Click on a model element of the project (e.g., on an element of the project browser, on a diagram or diagram element)
• Visualize the viewpoint state in the viewpoint manager

Open the Viewpoint Manager view

• Menu sequence [Window]/[Show View]/[Other…]
• In the "Kitalpha" section of the "Show View" window, select "Viewpoint Manager"
• Click on "OK"
