Inside the System File (Continued)

Navigation Services 1.1

Navigation Services provides new Open and Save dialogs, allowing users to locate and select files and other resources. Navigation Services 1.0 is delivered as a separate shared library in the Navigation Services SDK. In Mac OS 8.5, Navigation Services 1.1 is built in to the System file.
  • Event procedures now receive appropriate mouseDown events before they are processed by Navigation Services.

  • Event procedures now receive a slightly different parameter block (which is backward-compatible with 1.0 callers) that allows them to see the dialog item index of an item that has been selected by the user.

COMPATIBILITY NOTE
Navigation Services effectively obsoletes the Standard File package. Developers interested in future Mac OS compatibility are encouraged to replace their calls to Standard File with calls to Navigation Services.
