Mac OS 9 introduces the concept of packages. Packages are file objects that combine an application or document with supporting files in a container. By default, Navigation Services does not display packages in the browser list; if you want your application to recognize packages, specify the
kNavSupportPackages
constant in the
dialogOptionFlags
field of the
NavDialogOptions
structure that you pass in the
dialogOptions
parameter of various Navigation Services functions. If you want your application to be able to navigate packages, specify the
kNavAllowOpenPackages
constant in the same way. Package support is available in Navigation Services 2.0 and later.
