Abstract

A desktop publishing software program configured to propagate object content-defining and format-defining object properties so that user-defined object properties automatically propagate to other objects in the document. Object property propagation allows the author of the document to edit a number of linked objects by editing just one of the objects. To enable object property propagation, the desktop publishing software program includes a propagation table for each predefined layout. Each document is constructed from a number of components, and multiple instances of the same component may occur in a document. Each object has a name including an identifier and an instance code. The desktop publishing software program supports the following object property propagation rules, which may be applied to content properties and format properties separately: (1) do not propagate to any other objects; (2) propagate to objects in the same component whose identifiers belong to the same content or format group; (3) propagate to objects in the same document whose identifiers belong to the same content or format group; (4) propagate to objects in other components of the same document with the same identifiers and instance codes; and (5) propagate to objects in the same document whose identifiers belong to the same content or format group and save the object property in a registry so that the object property propagates to other documents as well.

receiving a layout selection command corresponding to a predefined layout for a document;

the layout comprising a predefined set of objects, each object having a set of object properties for defining a visible element of the document;
