Abstract

PURPOSE:To shorten the input waiting time by displaying a window set under an input waiting state after the end of its information processing job at the forefront side and setting again the previous state if no input is given to said window displayed at the forefront side for a fixed time. CONSTITUTION:A process control part 2 always checks the input given from an input device 6 and the information processing states of all windows and sends a window set under an input waiting state after the end of its task, if detected, to a CRT control part 3. The part 3 delivers the relevant window to a CRT display device 5 via a CRT memory 4 so that this window is set at the forefront side. Then the part 2 checks via a timer 2c whether or not an input is given to the window within a fixed time. If no input is given to the window, the part 2 transmits this fact to the part 3. The part 3 replaces the CRT display with the previous screen stored in a RAM. Thus it is possible to shorten the input waiting time and to produce no troublesomeness even though the window carrying out the current processing job is covered.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to process status display in an information processing device capable of displaying multiple windows on a display screen of a display device.

(Prior art and its problems) Conventionally, when an information processing device processes multiple pieces of information using multiple windows on the screen of a display device, when several windows are opened, the process may occur with a window that is hidden behind the screen. To find out whether the current process has finished, you have to move the window or call it to the front, which is inconvenient, and when you perform successive processes in a hidden window, you don't know when the previous process finished. This had the disadvantage of increasing unnecessary window calls and input waiting time.

(Means and effects for solving the problem) The present invention has been made in view of the above-mentioned circumstances. The process management means includes a timer circuit that determines the display time of the window and manages the process state in each window, and the control means controls the window display according to the execution state of the process, and executes multiple information processing. When the information processing that is being executed in the window that is hidden while the user is in The present invention provides an information processing device that returns to the previous state when no input is made.

〔Example〕

FIG. 1 is a block diagram showing the configuration of an information processing apparatus according to an embodiment of the present invention.

1 is a CPU that controls the entire information processing device, and a RAM that serves as a work memory for storing process data, etc.
It has 1a. Reference numeral 2 denotes a process management unit that examines and manages the process status of the CPU 1, and includes a ROM that stores a process management processing program (described later), a RAM 2b that is a memory for registering process data, and a timer circuit 2c. 3 is a CRT control unit that controls a CRT display device, and a ROM 3a that stores a window processing program to be described later.
and R as a working memory to expand process data.
It has AM3b.

4 is a CRT output memory, 5 is a CRT display device, and 6 is an input device such as a keyboard.

Figures 2 to 4 show the CRT of the information processing apparatus shown in Figure 1 when a multi-window is open and multiple information processes are being executed.
The state of the display device is shown. 2-1.3-1 is a CRT screen,
2-2 to 3-4 are windows in which information processing is being executed.

When there is an input from the input device 6 to execute unsealing information processing on the window of the CR7 display device 5, the process management section 2 transfers the information processing process to the CPU 1 and the CRT control section 3. The CPU 1 executes the information processing, and the CRT control unit 3 outputs a window for the information processing to the CRT memory 4. In FIG. 2, window 2-2 has just been opened, and windows 2-3 and 2-4 are information processing windows that were previously in the execution state. The process management section 2 constantly checks the input from the input device 6 and the information processing status of all windows, and when a task is completed and there is a window waiting for input, it notifies the CRT control section 3 of this fact. When the CRT control unit 3 receives notification of the end of information processing, the window is output to the CR7 display unit 5 via the CRT display 4 and displayed so that the window is brought to the front. When changing the CRT display, the CRT control section stores the state before the change in the RAM of 3a.

When the processing of information in window 2-3 is completed,
Through the operations described below, the CR7 display device 5 displays the screen shown in FIG. 3. The process management unit 2 indicates the end of information processing using the CRT.
When the control unit 3 is notified, the timer 2C checks whether there is an input in the window 3-3 within a certain period of time.

If there is, it informs the CRT control section 3 that there is no input unless it processes according to the input. When the CRT control section receives this notification, it stores it in the RAM and changes the display to the previous screen display (Fig. 2). FIG. 5 is a flowchart showing the process management operation of the process management unit related to the series of processes described above.

In step s1, the process management unit 2 checks whether there is an input from the input device to open a new window or to execute new information processing. If there is an input, it is registered in RAM2b, which is the process table, and the CPU
is transmitted to the CRT control unit 3 (step 32.S3).

If there is no input, the process directly advances to step s4.

In step S4, the process table is searched to determine whether all registered processes have been searched. If there is a process that has not been searched, the process status is checked via the CPUI in step S5. If the checked process is currently being processed, the process returns to step S4. If it is in the input waiting state (processing completed), the process advances to step S7, the process is removed from the process table, and the CRT control unit 3 is notified of the process completion (step S8).

It is checked in step s9 whether there is any new input in the window of the terminated process. If so, the process returns to step S2. If not, it is checked in step SIO whether a certain period of time has passed since step S7. If the elapsed time has not elapsed, the process returns to step S9, and if the elapsed time has elapsed, the CRT control unit 3 returns to step Sll.
A command is given to return to the previous display state, and the process returns to step S4.

When the process table search is completed in step S4, the process returns to step S1.

FIG. 5 is a flowchart showing the window processing operation of the CRT control section 3. In step S12, it is checked whether there is any notification from the process management section 2 in step S3. If so, the current CRT screen display information is stored in the RAM of 3b in step S13, and CRT display output is performed according to the notification (step 514); if not, in step S1
5, it is checked again from the process management section 2 whether there is any notification in step S8, and if not, the process goes to step S19.
If there is, it is checked in step 316 whether there is a hidden part of another window in the window of that process, and if not, the process goes to step S19, if so, step S
Step 17 saves the current CRT screen display to RAM and outputs the window of the process that received the notification to the forefront (
In step S8), if it is not checked in step S19 whether there is any notification from the process management unit to return to the previous screen, the process returns to step S12. If so, save the current CR7 screen to RAM.
(step 520), the previously saved RA
The contents of M are output to the CRT memory and displayed (step 521).

(Effects of the Invention) In the information processing device according to the present invention, when many windows are opened and a plurality of pieces of information are loaded at the same time, when the process ends and the input is waited, the window appears in the foreground. This has the effect of not only being able to grasp the status of processes that are no longer visible, but also shortening the time it takes to wait for input.

Furthermore, the window that appears in the foreground returns to its original position after a certain period of time, so it is not bothersome even if the window that is currently being processed is hidden.
