CHAPTER 2

Finder Objects

16 Using Object Class Deﬁnitions

tell application "Finder"

set position of file "MyFile" to {29, 235}

end tell

The file in this example must be located on the desktop. A ﬁle can have only

one Position property, distinguished from the other properties of the ﬁle by its

label, position.

The Properties section of an object class deﬁnition lists all the property labels

deﬁned for that object and describes how to use them, including the class used

for each property’s value and whether or not the property can be modiﬁed.

Some objects inherit some or all their properties from other related objects. For

example, the deﬁnition for File that begins on page 61 lists several properties

that are inherited from the object class Item and several that are deﬁned

speciﬁcally for class File.

IMPORTANT

A property name has no plural form, even if you use it to

refer to more than one property. ▲

This script gets a list of the names of the ﬁles at the top level of the startup disk:

tell application "Finder"

name of files in startup disk

end tell

If you replace name with names, the script won’t compile.

Element Classes 2

Elements are objects contained by an object. For example, a folder can contain

ﬁles and other folders. The element classes listed in an object class deﬁnition

show what kinds of elements objects of that class can contain. An object can

contain many elements or none, and the number of elements of a particular

class may change over time.

A ﬁle can be an element of other Finder objects in which ﬁles can be stored,

such as folders, disks, or the desktop; so File is listed as one of their element

classes. The deﬁnition for object class File that begins on page 61 indicates that

a ﬁle can’t contain any other elements.
