Script Objects

Script objects are objects that you define and use in scripts. Like the application and system objects described earlier in this guide, script objects have properties and can respond to commands. Unlike application or system objects, script objects are defined within scripts.

AppleScript's script objects have capabilities common to object-oriented programming languages. For example, you can define groups of script objects that share properties and handlers, and you can extend or modify the behavior of a handler in one script object when calling it from another script object.

This chapter describes handlers in the following sections:

About Script Objects provides a brief overview of script objects and includes a simple example.
Defining Script Objects provides the syntax for defining script objects.
Sending Commands to Script Objects describes how you use Tell statements to send commands to script objects.
Initializing Script Objects describes how AppleScript creates a script object with the properties and handlers you have defined.
Inheritance and Delegation describes how you can share property and handler definitions among script objects without repeating the shared definitions.
Using the Copy and Set Commands With Script Objects describes differences in the way the Copy and Set commands work with script objects. It also describes how to write a handler that creates copies of script objects.
