deoExitTrigger
deoExitTrigger(
g_application
[ l_args ]
)
=> t / nil
Description
When a plugin is being removed from a window, Design Editor calls the exit trigger before disabling all GUI components of the plugin and removes the plugin only if this trigger returns a non-nil value. The return value of the exit trigger is ignored if the window on which the plugin is installed is being closed. The default implementation is a no-op, and always returns t.
