System-Provided Images that Indicate Privileges

Mac OS X v10.5 and later provides images that represent the standard “user,” “group,” and "all” categories of permissions or privileges, including access control lists (or ACLs). Each of these images is shown in Table 11-6, along with its meaning and name. It is recommended that you use these images to clarify which users have permissions to read, write, or execute an item. These images allow you to avoid displaying Unix-style permissions indicators, such as rwxr-xrw-, which are suitable only for very sophisticated users.

Note that the “user group” permissions image shown in Table 11-6 looks similar to the image for the “user accounts” preferences category, shown in Table 11-4 (page 155). As with all system-provided images, however, similar appearance does not imply similar meaning or usage. Be sure to avoid using system-provided images incorrectly.

A System-Provided Drag Image

Mac OS X v10.5 and later provides an image you can display when a user drags multiple documents or items. As with all system-provided images, you should use the multiple-documents image in accordance with its intended meaning. Figure 11-29 shows the multiple-documents drag image. (The constant name of the drag image is NSImageNameMultipleDocuments.)
