Chapter 8. The Anatomy of Lingo > Points to remember

Points to remember

These are the main points I hope you've gleaned from the preceding pages:

  • Lingo is a living language; its vocabulary is growing and changing. Each major revision of Director brings with it new terminology and sometimes the abandonment of outmoded Lingo.

  • There are 41 distinct built-in occasions when Director looks for Lingo scripts to execute. These occasions are called events.

  • When an event is detected, Director sends a message to that effect. This message is routed in a certain order to various Lingo locations.

  • The scripts located in these various locations are classified as objects, and the order in which they receive the message is known as the object hierarchy.

  • If an object contains a script pertaining to the event, the object will execute it. Such a script is called an event handler. If an object doesn't have a relevant event handler, it will pass the message further down the hierarchy.

  • With one notable exception, the flow of a message usually stops at the first relevant event handler. But you can continue the message transmission down through the hierarchy by using the pass command, or you can stop the flow prematurely with stopEvent.
