Using the AppCache.Load method to run applications

Applications are normally started when a user selects a tile in the Neptune launchpad. Applications can also be started in a range of other scenarios, for example, an application can be started just by running the direct URL.

If you only need to run one application, Neptune recommends running the application inside the Neptune launchpad. You can set the launchpad to only run this one application. By doing this, you still get the benefit of the launchpad framework.

Another way to start an application is by code using the AppCache.Load method. By doing this in the Neptune launchpad, you can take advantage of all the launchpad events. You can also run applications inside another application in a parent frame, making your Neptune applications reusable in a wide range of scenarios.

When an application is started using AppCache.Load, the onInit, and onBeforeDisplay event handlers are called, though not in the same way in all the different loading scenarios.

The following matrix provides an overview of the different loading scenarios to consider when using the AppCache.Load method.
