Abstract

PURPOSE:To easily change model information having complicated structure, to convert a window into various display forms and to flexibly convert data by setting not only a character string but also the window to be display elements which can be selected. CONSTITUTION:A control part 101 analyzes a selection operation by a user input part 106 and selects/displays the constitution element A selected in a constitution element display part 105. When the user input part 106 depresses a copy key during selection display, the control part 101 obtains model information which the constitution element A expresses from a model information definition part 102, generates a selection state expressing object and stores it in a temporary data holding part 104. When a paste key is depressed by following the selection operation of the constitution element B by the user input part 106, the control part 101 converts the stored selection state expressing object in an appropriate display form in a data conversion part 103 and displays or exchanges it in the constitution element B on the constitution element display part 105.

[Problems to be Solved by the Invention]
As seen in the application group on Open Systems of Rosystems, the transfer and movement of character string level data can be done not only inside the same application but also through different applications by using the clipboard for saving temporary data. It could be done in between. However, since there is no means provided for transcribing or moving windows, it is difficult to provide a system that handles complex data structures with a user interface for flexibly changing data. In addition, it makes it possible to easily display, change, and reuse a plurality of types of data including object-oriented data (JP-A-2-28).
7830), when executing information transfer via the clipboard, a protected field and an unprotected field are set in the source space and the destination space (Japanese Patent Laid-Open No. 3-127246), and even when the data attribute is converted, A multi-window method in which the data attribute before conversion is held and the data before conversion can be referred to even if there is a processing request for the data after conversion (JP-A-62-2519)
79) and the like have been proposed, but none of them was able to transfer or move the window itself.

The present invention has been made to solve the above-mentioned problems. In addition to a character string, a window is provided as a selectable display element, and it is possible to transfer or move within an application by the same operation method as in the case of a character string. By doing so, it is an object of the present invention to provide a data processing device that facilitates construction of an application for expressing model information having a complicated data structure.
