Availability: Macintosh.
The aetypes defines classes used to represent Apple Event data
descriptors and Apple Event object specifiers.
Apple Event data is contained in descriptors, and these descriptors
are typed. For many descriptors the Python representation is simply the
corresponding Python type: typeText in OSA is a Python string,
typeFloat is a float, etc. For OSA types that have no direct
Python counterpart this module declares classes. Packing and unpacking
instances of these classes is handled automatically by aepack.
An object specifier is essentially an address of an object implemented
in a Apple Event server. An Apple Event specifier is used as the direct
object for an Apple Event or as the argument of an optional parameter.
The aetypes module contains the base classes for OSA classes
and properties, which are used by the packages generated by
gensuitemodule to populate the classes and properties in a
given suite.
For reasons of backward compatibility, and for cases where you need to
script an application for which you have not generated the stub package
this module also contains object specifiers for a number of common OSA
classes such as Document , Window , Character , etc.
The AEObjects module defines the following classes to represent
Apple Event descriptor data:
class Unknown( |
type, data) |
-
The representation of OSA descriptor data for which the aepack
and aetypes modules have no support, i.e. anything that is not
represented by the other classes here and that is not equivalent to a
simple Python value.
-
An enumeration value with the given 4-character string value.
class InsertionLoc( |
of, pos) |
-
Position
pos in object of .
-
A boolean.
class StyledText( |
style, text) |
-
Text with style information (font, face, etc) included.
class AEText( |
script, style, text) |
-
Text with script system and style information included.
class IntlText( |
script, language, text) |
-
Text with script system and language information included.
class IntlWritingCode( |
script, language) |
-
Script system and language information.
-
A quickdraw point.
class QDRectangle( |
v0, h0, v1, h1) |
-
A quickdraw rectangle.
-
A color.
-
An OSA type value with the given 4-character name.
-
An OSA keyword with the given 4-character name.
class Range( |
start, stop) |
-
A range.
-
Non-numeric absolute positions, such as
"firs" , first, or "midd" ,
middle.
class Logical( |
logc, term) |
-
The logical expression of applying operator
logc to
term .
class Comparison( |
obj1, relo, obj2) |
-
The comparison
relo of obj1 to obj2 .
The following classes are used as base classes by the generated stub
packages to represent AppleScript classes and properties in Python:
class ComponentItem( |
which[, fr]) |
-
Abstract baseclass for an OSA class. The subclass should set the class
attribute
want to the 4-character OSA class code. Instances of
subclasses of this class are equivalent to AppleScript Object
Specifiers. Upon instantiation you should pass a selector in
which , and optionally a parent object in fr .
-
Abstract baseclass for an OSA property. The subclass should set the class
attributes
want and which to designate which property we
are talking about. Instances of subclasses of this class are Object
Specifiers.
class ObjectSpecifier( |
want, form, seld[, fr]) |
-
Base class of
ComponentItem and NProperty , a general
OSA Object Specifier. See the Apple Open Scripting Architecture
documentation for the parameters. Note that this class is not abstract.
