Interface Manipulation Example

The Interface Manipulation example demonstrates the following:

• How to create a dialog at start-up that gives the option of using VR-Forces GUI in alternate modes
• How to add menus and menu items to the GUI
• How to create a simple scenario player option that limits user capabilities to simply loading and observing scenarios
• How to create a simple scenario viewer option that limits user capabilities to simply observing simulation activity occuring over the network

The Interface Manipulation example creates a starting dialog that allows different options for the GUI to be entered into. One is the normal VRF GUI, one is a "Simple Scenario Player" that allows the user to load terrains or scenarios and observe them - but not interact with them. The other option created by this example is a "Simple Scenario Viewer" that allows the user only to observe simulation activity, but not to interact with it in any way.
