System information

Besides fixing the specific problem, which was an internal bug in Classic, a change was made to Classic USB policy

for MacOS X 10.2 and later. The new policy is that if a USB device has multiple interfaces, some of which are of the

class that they might have been opened by Classic to be visible to the emulated MacOS 9 environment, yet others of

which are not and thus might successfully match to a Mac OS X driver, then the entire device is not opened by

Classic and thus will only function in the Mac OS X environment. In other words, "split cases" where a USB device

has some interfaces in use by Classic and some by "X" drivers, will no longer be allowed. For additional

information on which devices are seized by Classic, search for the document "Classic USB Device Arbitration" on

developer.apple.com and in the USB SDK; it has been updated for Jaguar. (r. 2761572).

Calling LMGetBootDrive() from classic now returns the correct volume reference number. (r. 2756118).

It is now possible for classic applications to extract the process serial number from an Apple event they received

from a Mac OS X application, save that process serial number, and later use it to send an Apple event to that

application. (r. 2392561).

A problem where Application Died events were not being sent for Classic applications that had unexpectedly quit

has been corrected. (r. 2922254).

When called from a Classic application, PBHGetDirAccess was failing with a paramErr (-50). This has been

corrected. (r. 2908703).

A problem where Gestalt() was returning the wrong system version - 9.2 rather than 9.2.1 - when called in a

classic application running in the Classic environment in Mac OS X 10.1 has been corrected. (r. 2771448).

Better Apple Event error checking and handling has been added to Classic Support's Apple Event handlers. This

helps prevent possible crashes inside Classic if an error occurred while an Apple Event was being processed. (r.

2749114).

A problem where applications in the Classic environment could not connect to localhost tcp servers running in Mac

OS X has been fixed. (r. 2831535).

A problem where PAP spoolers running in the Classic environment could not be seen over AppleTalk by

PrintCenter has been fixed. (r. 2720750).

Cocoa

A set of object-oriented frameworks that support rapid development and high productivity, using a dynamic runtime and

rich object hierarchy. Please refer to file:///Developer/Documentation/ReleaseNotes/AppKit.html on your 10.2 system

for detailed information on changes in Cocoa in 10.2.

AppKit

AppKit is a framework that provides graphical objects with default behaviors for rapid application development, including

windows, panels, buttons, menus, scrollers, text fields, and more.

The declaration of NSCopyBitmapFromGState() listed in NSGraphics.h was removed. (r. 2781664).

NSColor's +colorWithPatternImage method now returns an auto-released object, where before it did not

(r.2797049) .

AppKitJava

AppKitJava refers to the Java-language-specific portion of AppKit.

-outlineView:itemForPersistentObject: now has a Java based counterpart named

outlineViewItemForPersistentObject. As well, -outlineView:persistentObjectForItem: now has the Java based

counterpart outlineViewPersistentObjectForItem. (r. 2837824).

Cocoa-Java's NSSavePanel didn't have a way to set wether or not the extension is shown. Now, the following APIs

can be used to control extension hiding: setCanSelectHiddenExtension, isExtensionHidden, and setExtensionHidden.

(r. 2830102).
