Callback

Description

Fired after the plug-in loaded (that is, after XSILoadPlugin returns). For example, Init is fired when you start Softimage or load the plug-in in the Plugin Manager.

Used to initialize the custom display window.

Notify

Fired when something happens in the scene, such as a parameter change or selection change.

Term (Custom Display)

Fired when the top-level window is destroyed.

Unload, Reload

Fired when the plug-in is cached (reloaded) and uncached (unloaded). By default, all plug-ins are cached, but users can remove a plug-in from the cache (by right-clicking a plug-in in the plug-in tree and clearing the Cached checkmark).
