System information

program is only interested in finding the control under the mouse, but not the part code describing the part of the

control under the mouse. (r. 2879400).

Date & Time Utilities

The Date & Time Utilities provide facilities for accessing the clock chip and APIs for converting dates between various

formats.

Fixed an obscure conversion problem with StringToDate() where it could fail on the date of January 1 of any year

where (year mod 400) equals 101. (r. 2860198).

Added support for time zone support for cities in Portugal, Croatia, and Slovenia. (r.2946953) (r. 2928698).

Dialog Manager

The Dialog Manager manages user interactions with windows containing controls arranged and positioned using dialog layout

templates.

RunStandardAlert disposes of the dialog before returning. More comments have been added in Dialogs.h for

RunStandardAlert and CreateStandardAlert to clarify the allocation/deallocation issues. (r. 2828656).

Problems where the DITL accessor routines could crash if passed NULL dialog item list handles have been

corrected. (r. 2603639).

Memory leaks that could occur when using GetNewDialog or DisposeDialog with sheets have been corrected. (r.

2967411).

A problem where GetDialogItem could alter the font information in the active window port, rather than the explicit

dialog port, has been corrected. (r. 2938978).

Display Manager

The Display Manager allows users to dynamically change the arrangement and display modes of the monitors attached to

their computers.

Problems with calling DMRegisterExtendedNotifyProc with kFullDependencyNotify have been corrected. (r.

2788058).

Added new Display Manager notifications for display sleep and wake. Check gestaltDisplayMgrSleepNotifies to make

sure it is available and see Displays.h for kDMNotifyDisplayWillSleep and kDMNotifyDisplayDidWake. (r.

2806290).

Drag Manager

The Drag Manager supports drag-and-drop operations between windows and applications.

A new constant, kDragStandardDropLocationTrash, has been added in Drag.h. When used with the new API,

SetStandardDropLocation, an alias to the Trash will be set as the drop location (r. 2916609). (r. 2829056).

Calling SetDragImage() can be called multiple times during a Drag to update the drag image. Unfortunately, there

was a problem where the image flags parameter was being ignored after the first call to SetDragImage(). Now, the

flags parameter is observed on subsequent calls to SetDragImage. This allows callers to turn on and off the drag

region during a drag by changing the kDragRegionAndImage flag. (r. 2641813).

A problem where the region offset of the masking region was being ignored by SetDragImage has been corrected. (r.

2640917).

A new API, SetDragImageWithCGImage, has been added to Drag.h to enable callers to specify a CGImage as a drag

image. (r. 2916609).
