Science Dept., University of Amsterdam Lines: 41 Summary: Summary: The strange resource mentioned is the so called "signature" resource of an application. It must have a resource type equal to the files creator, in order to enable the finder to associate the application with its specific data, such as icons. This specific data is specified in the so called bundle, a resource (type BNDL), that specifies the icons the finder must display for the application, as well as for the documents created by the application. In the bundle usually there are references to three types of resources: 1) To the signature resource. By the way, the signature may have any type, must have resource id 0, and must be the first resource defined for the application. 2) The ICN# resources. Icon lists contain an icon and its mask for each resource id. Such a pair must be defined for every different file typ the application creates, including its own file, with the type APPL. 3) FREF resources (file references), which tell the finder wich ICN# belongs to which file type. Some applications do not have a bundle resource. In the case the finder assigns them the default icons for application (the hand icon) and documents. -- Dolf Starreveld Computer Science Department University of Amsterdam The Netherlands {philabs, decvax, seismo}!mcvax!uva!dolf
