Abstract

PURPOSE:To change a terminal to be used without interrupting work by providing the computer system with a means for copying resources depending upon respective applications to another window system while holding the structure. CONSTITUTION:An inherent resources copying device 12 copies resources depending upon the applications while holding its structure switches the copied contents to another bit map display terminal, e.g. the device 12 copies from a window system 2 to a window system 6. The skeleton of the structure of the window resource 4 is copied as the skeleton 15 of the resource to the memory of the application, the display of the displayed window is stopped and the resources information is stored until the information is displayed in any terminal in the future. Consequently, the terminal to be used can be changed without interrupting the work, and even when an operator leaves the terminal on the way of operation, the working process up to that time is stored so that the operation can be successively continued by an optional terminal.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is applied to a computer system in which a plurality of computers are connected to a local area network.

TECHNICAL FIELD This invention relates to local area networks and multi-window systems, and more particularly to managing windows.

〔overview〕

The present invention is a computer system in which a plurality of computers having a multi-window system are connected to one local area network, and works by copying resources dependent on each application to another window system while preserving the structure. This allows you to change the terminal you are using without interrupting your work, saves the progress you have made up to that point, and allows you to continue working on any bitmap display terminal.

[Conventional technology]

Some conventional multi-window systems include window systems (e.g., X

However, even in such a window system, the ability to move or redisplay a window is limited to the bitmap display terminal that originally opened the window.

[Problem that the invention seeks to solve]

In the conventional window management described above, the redisplay of a window is limited to the bitmap display terminal where it was initially displayed, so when changing the bitmap display terminal used, the application that uses that window must be It is necessary to close the application and restart the application on other bitmap display terminals. When switching bitmap display terminals using this method, the disadvantage is that the work is interrupted and the work up to that point must be restarted from the beginning.

The present invention eliminates these drawbacks, and allows you to change the terminal you are using without interrupting your work.You can also save the progress of your work even in the middle of your work, and later use any bitmap display terminal to perform the work. The purpose is to provide a system that can continue.

[Means for solving problems]

The present invention provides a first computer having an application program means and resources, and a plurality of computers having resources and a multi-window system including a bitmap display terminal having a window and a window system, in one local area network. In a computer system connected to a second computer, there is provided a means for copying resources dependent on an application onto the local area network while preserving its structure and switching to another bitmap display terminal, and stopping display of a window. and a means for redisplaying the stored resource information on a designated bitmap display terminal when a display instruction is received. It is characterized by comprising a unique resource copying device including:

[Effect]

Copy application-dependent resources to another window system while preserving their structure and switch bitmap display terminals. In addition, the display of the currently displayed window is stopped and the resource information is stored until it is displayed on some bitmap display terminal in the future. Redisplay.

This allows you to change the terminal you are using without interrupting your work, and even if you leave the terminal in the middle of your work, you can save the progress of your work up to that point and use it later on any bitmap display terminal. I can continue.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

The figure is a block diagram showing the configuration of an embodiment of the present invention.

In the embodiment of the present invention, an application program means 10 and a resource 1 are connected to one local area network 11.
5 and a first calculator 9 with a window 13.14.
a plurality of second computers 1 each having a bitmap display terminal 3.7 and a multi-window system including a window system 2.6 and resources R4,8;
．． 5 is connected to the local area network 11, and there is a means for copying the resources dependent on the application while maintaining its structure and switching to another bitmap display terminal, and a means for copying the resources dependent on the application while maintaining the structure and switching to another bitmap display terminal, and a means for canceling the display of the window and copying it to another bitmap display terminal. A unique resource copying device 12 includes means for storing resource information until it is displayed on a display terminal, and means for redisplaying the stored resource information on a designated bitmap display terminal when a display instruction is received. Be prepared.

The embodiment of the present invention will be described as having two multi-window systems, window system 2 and window system 6.

The window system 2 manages a bitmap display terminal 3 connected to the computer 1. On computer 9 (calculator 1 and computer 9 may be the same computer)
The application program means 10 in operation displays a window 13 on the window system 2 via the local area network 11. The window system 2 allocates and holds resources 4 specific to the application program means 10 for displaying the window 13.

This resource 4 includes, for example, windows, fonts (fonts), etc.
, memory for non-display drawing, etc.

A computer 5 is further connected to the local area network 11 (the computer 9 and the computer 5 may be the same computer), and a window system 6 for managing the bitmap display terminal 7 is present there.

A window through which the application program means 10 interfaces with the user is initially displayed on the bitmap display terminal 3. That is, the application program means 10 operates in cooperation with the window system 2.

Displaying windows on other computers via the local area network 11 in this way is possible using conventional window systems (such as the X Window System).
However, in the conventional window system, it was impossible to dynamically switch the bitmap display terminal for displaying, for example, from the bitmap display terminal 3 to the bitmap display terminal 7.

This is because the resources for each application exist in an unorganized manner inside the window system, and even in arbitrary variables in the application program, and it is quite difficult to copy these resources to another window system. be.

In the present invention, the resources related to these applications are organized into a tree structure shown in resource 4 for each application, and the resources specific to each application are collectively managed, thereby making it possible to dynamically switch the bitmap display terminal to be displayed. did.

The unique resource copying device 12 is a device that copies resources that depend on these applications while maintaining their structure.
For example, window resources 4 in application program means 10 can be copied from window system 2 to window system 6. This copying corresponds to switching the bitmap display terminal for display.

It also has a function of copying the framework of the structure of the window resource 4 to the memory of the application as a resource framework 15. This copying is performed in order to stop displaying the currently displayed window and store the resource information until it is displayed on some bitmap display terminal in the future. This stored resource skeleton 15 is copied onto the window system and redisplayed in the window of any bitmap display terminal. This unique resource copying device 12
can be realized by hardware or software.

〔Effect of the invention〕

As explained above, according to the present invention, by dynamically switching the bitmap display terminal on which the window is displayed, it is possible to change the terminal to be used without interrupting the work. Even if you leave the site, you can save the work progress up to that point and continue the work later on any bitmap display terminal.
