Method and apparatus for dynamic update of an existing object in an object editor    
United States Patent5652884   
Link to this pagehttp://www.wikipatents.com/5652884.html
Inventor(s)Palevich; Jack H. (Sunnyvale, CA)
AbstractUser interface objects are stored in a user interface object archive which is a database physically located in the shared library of an associated application program. In order to facilitate "localization", or preparation of an application developed in one language for use in an "area" or a locale which uses another language, the user interface objects are stored in a hierarchical locale tree within the archive. All objects are stored in the base or root of the hierarchy, but only those objects which require a translation are stored in an area associated with a more specific locale. At runtime, a complete collection of objects is assembled by starting at the desired locale and proceeding up the hierarchy level-by-level. Translated objects at lower levels of the hierarchy "override" those at higher levels so that the most complete translations of each object are obtained during this search. The user interface objects which are stored in an archive are actually created via a predefined "constructor" program, and, in order to allow newly-created user interface objects to use the predesigned constructor program, each user interface object is contained in a special "escort" object that interfaces with the constructor program. A user can edit an existing object, and change its class. This results in a new object of the new class being created. The existing attributes of the old object are transferred to the new object. Only the attributes known to the common base class or classes of the two objects are transferred. The new object is substituted for the old object, and the old object is deleted.

A user interface object archive system according to claim 1 further comprising tree transversal means, operatively coupled to said storage means, for traversing said locale tree starting at said other locale level associated with the second local and proceeding to said root locale level to assemble a set of available user interface objects from said user interface objects stored in said other locale level and said root locale level.

5. A user interface object archive system according to claim 4 wherein said tree transversal means comprises means for retrieving copies of user interface objects from said user interface objects stored in said other locale level associated with said second locale and copies of user interface objects stored in said root locale level.

6. A method for use in an object oriented programming (OOP) based computer system which builds user interface objects while a runtime environment is operational and which creates new application programs without halting said runtime environment, said method comprising the steps of:

(a) storing objects in a hierarchical locale tree in a storage device, said locale tree having a root locale level associated with a first locale and at least one other locale level associated with a second locale;

A program storage device readable by a computer system tangibly embodying a program of instructions executable by the computer system to perform an object oriented programming (OOP) based method which builds user interface objects while a runtime environment is operational and which creates new application programs without halting said runtime environment, the method embodied on the storage device comprising the steps of:

(a) storing objects in a hierarchical locale tree in a storage device, said locale tree having a root locale level associated with a first locale and at least one other locale level associated with a second locale;

(a)(i) creating a structure for said hierarchical locale tree which is associated with said shared library.

13. A program storage device according to claim 11 wherein said method further comprises the step of:

(g) creating an archive viewer object from a predefined object class template and information about said objects stored in said storage device, said archive viewer object comprising a displayable form of said hierarchical locale tree of objects stored in said storage device.

14. A program storage device according to claim 11 wherein said method further comprises the step of:

(g) traversing said locale tree starting at said other locale level associated with the second local and proceeding to said root locale level to assemble a set of available user interface objects from said user interface objects stored in said other locale level and said root locale level.

(g)(i) retrieving copies of user interface objects from said user interface objects stored in said other locale level associated second locale; and

(g)(ii) retrieving copies of user interface objects in said root locale level.

1. Field the Invention

This invention relates generally to improvements in computer systems and, more particularly, to operating system software for managing user interface objects in a windows-oriented graphical user interface.

2. Background of the Invention

One of the most important aspects of a modern computing system is the interface between the human user and the machine. The earliest and most popular type of interface was text based; a user communicated with the machine by typing text characters on a keyboard and the machine communicated with the user by displaying text characters on a display screen. More recently, graphic user interfaces have become popular in which the machine communicate
