The operation of a conventional personal computer configured as described above when performing multi-window display processing will be described.

When displaying a multi-window in the above system, window management information is set in the memory 2. This mainly stores the attributes of each window, such as its position on the screen, size, and background color.

When a command to display characters, figures, etc. to a window is received from an application program, an area to be displayed is set using management information corresponding to the window designated for display, and only the inside of that area is displayed. This allows drawing on multiple windows.

When processing such as moving, reducing, or deleting a window is performed in the above system, a command to update the screen is sent to the application program that has each window. The application program that receives this command analyzes the command and performs display according to the command. By executing this command by an application program having each window, the multi-window display is reconfigured.

In many personal computer systems, window control information is transmitted by allocating a shared memory area for each window and writing window control information there, or by using the interprocess communication function of the operating system that supports multitasking. This is achieved by sending window control information to each process and process.

Problems to be Solved by the Invention However, in the above configuration, since control information is transferred to each window using software, it takes time to transfer window control information, and multi-window display such as updating or deleting windows is difficult. The reconfiguration process of

Create elements of list structure. Next, the window control information management device memorizes the address to the area where the window control information has been copied, if the content of the information management device corresponding to the window specified as the transfer destination is empty, and stores the address and transfers the address to the area where the window control information is copied. If the address is stored in the information management device corresponding to the window, the address is added to the window control information of the last element of the window control information list indicated by the address, and the list structure is extended, thereby allowing the corresponding window to be added to the window at high speed. Transfer control information.

When deleting window control information, the window control information management device checks the information management device corresponding to the specified window, deletes the first element of the window control information list indicated by the stored address, and deletes the next element. address in the information management device. If there are no following elements, 0 is stored.

Embodiment FIG. 1 shows the configuration of a multi-window control information management device in an embodiment of the present invention.

In FIG. 1, 6 is a CPU, 7 is a memory, 8 is a display memory, 9 is a display control device that creates a video signal from the display memory, 10 is a CRT, and 11 is a list structure corresponding to each window on the memory 7. 12 is an arithmetic register that compares the value of the window number stored in the information management register with a specified value; 13 is a memory T; The area specified in
A data transfer device that transfers a specified data size and a specified area; 14 is window control information that controls the data transfer device 13, arithmetic register 12, and information management register 11 to create, delete, and transfer window control information; It is a management device.

FIG. 2 shows the configuration of the information management register 11.

The information management register 11 is composed of a plurality of registers,
Each register stores the number of a window and the address to the window control information list structure corresponding to that number2.
It consists of a combination of two storage units. 16 is an index section indicating the number of the corresponding window; 16
is an address indicator that stores an address to the window control information list.

FIG. 3 shows the structure of the window control information list. The window control information list is configured such that one piece of window control information is one element of the list, and the oldest element points to the address of the newer element in the order in which it is sent to the window.

18t [address indicating section indicating the head position of the window control information list of the information management register 11; 19 an attribute section storing the attributes of the window control information in the memory 7;
20 is a next address storage section that stores the location of the next window control information; 21 is a data size storage section that stores the data size of the window control information; and 22 is actual window control information.

The operation of the multi-window control device of this embodiment configured as described above will be described below.

First, the operation of transferring window control information to a designated window will be described. First, the application program creates a window control message (window redrawing, window size enlargement or reduction, etc.) to be executed for the window to be controlled. Then, it specifies a transfer destination window and issues a transfer command to the window control information management device 14. The movement of the window control information management device 14 that received this transfer command is
This will be explained using the flowchart shown in the figure.

3o, the window control information management device 14 first secures an area on the memory 7 to store the window control information. The size secured at this time is an area of the size necessary to create one element of the list structure shown in FIG.

Next, at 31, the window control information management device 14:
The data transfer device 13 is instructed to transfer the window control information from the area where the window control information specified by the application program exists to the area secured in the process 3o.

At step 32, the window control information management device 14 compares the designated window number with the contents of the index section 16 in the information management register 11 using the calculation register 12, and checks whether the same number exists. If a corresponding index section does not exist, one set of unused registers in the information management register 11 is secured.

33, the window control information management device 14 checks the value of the address instruction i1e of the corresponding index section,
If the content is 0, the process moves to 34, and if it is not 0, the process moves to 36.

At step 34, the start address of the transferred window control information is stored in the address instruction section 16.

In step 36, since the start address of the window control information list has already been registered in the address instruction unit 16, the window control information management device 14 first traces the list structure and moves to the last element of the window control information list. Next, the first address of the transferred window control information is stored in the next address storage unit 20 of the last element of the window control information list. As a result, the element is added to the window control information list for the specified window.

At 36, the window control information management device 14 sets 0 in the next address storage unit 2o of the window control information of the final element of the window control information list newly added in the process of 34 or 36.

Through the above processing, the window control information is transferred to the designated window.

Next, the process of reading window control information will be explained.

An application program that has a window instructs the window control information management device 14 to receive window control information for the window that it owns. The process of the window control information management device 14 that is requested to receive window control information for a designated window will be explained using the flowchart shown in FIG.

First, in step 37, the window control information management device 14 uses the arithmetic register 12 to compare the contents of the index section 16 in the information management register 11 to find a register corresponding to the specified window.

In step 38, the window control information management device 14 determines whether the corresponding information management register 11 does not exist or if the content of the address instruction section 16 of the information management register 11 is 00.
If so, the application controller is informed that there is no window control information, and this process is terminated. If it exists, the process moves to 39.

In step 39, the window control information management device 14 uses the data transfer device 13 to transfer the actual data 22 of the window control information to the area specified by the application.

At step 4o, the window control information management device 14 stores the contents of the next address storage section 2o of the transferred window control information in the address instruction section 16 of the corresponding window of the information management register 11.

In step 41, the window control information management device 14 performs an operation of reading window control information by performing 0 or more processes to release the area of the transferred window control information.

As described above, according to the present embodiment, information that stores and manages both the memory location of the window control information that gives control instructions to the window, such as redrawing the window, and the number indicating the window to which the window control information is to be sent. A management device, a data transfer device that transfers specified window control information to a specified memory area in a specified size, and a calculation result that compares the number indicating the window stored in the information management device with the specified value. and a window control information management device that generates, deletes, and transfers the window control information on the memory indicated by the information management device using the calculation register and the data transfer device. This allows window control information to be transferred and managed to the corresponding window at high speed.

As described in detail, according to the present invention, window control information can be transferred to the corresponding window at high speed, so the reconfiguration process of multi-window display, such as updating or deleting windows, becomes faster, and the user Immediate response to processing can be obtained. Furthermore, since the transfer and management processing of window control information is automatically performed, the program for window system information management can be simplified and the program size can be reduced, which has a great practical effect.
