Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-window system for displaying in a plurality of windows.

UNIX such as workstations in recent years
With the spread of X windows in the system, it is required to develop software that effectively uses the multi-window function of X windows. Even in graphics software such as graph display, there is a strong demand for software that effectively uses the multi-window function. Therefore, it is desired to display in a plurality of windows without changing the conventional graphics software.

[0003]

2. Description of the Related Art There is no multi-window system such as X window in the environment of a conventional graphics display in a large-scale computer. The graphics software such as the graph display created above has a structure in which a single screen (window) is taken into consideration, as shown in FIG.

Further, recently created graphics software is structured from the beginning on the premise of a multi-window system such as X window, and a plurality of screens (windows) are recognized by a technique such as selection / switching of display screens. It has become software.

The following is a brief description of FIG. Figure 8
Shows an explanatory view of the prior art. FIG. 8A shows a block diagram of conventional graphics software.

In FIG. 8A, the system main body 21
Is composed of a graphics data creation process 22 for creating a graph, sending a graphics code and giving a display instruction, and the like.

The graphics display 23 is for displaying on the display based on the received graphics code, and is composed of a display process 24 for performing a display operation, a display and the like.

Next, the operation of the configuration of FIG. 8A will be briefly described with reference to the flowchart of FIG. 8B. Figure 8
In (b) of S, in S31, the graphics data creation process 22 reads data.

In step S32, a graph is created. S33
Sends the graphics code to the display process 24 as a display instruction.

In step S34, the display process 24 performs a display operation, and in step S35, the display is displayed on the display as illustrated. S36 is the graphics data creation process 22.
Changes the line type.

In step S37, a clear graphics code is sent as a screen clear instruction. In S38, the display process 24 performs a screen clear operation, and in S39, the screen is cleared on the display as illustrated.

In step S40, the graphics data creation process 22 sends a new graphics code as a display instruction. In step S41, the display process 24 performs a display operation, and in step S42, a graphic with the line type changed as shown in the figure is displayed (here, a dotted graphic is displayed).

As described above, conventionally, when the line type of the display A in S35 is changed from the solid line to the dotted line, the display A is first cleared to display A'as shown in S39, and then S4.
As shown in FIG. 2, the display A ″ in which the line type is changed to the dotted line is displayed.

[0014]

The above-mentioned conventional graphics software is conscious of only a single screen (window), and clears the original display A even when changing the type of line, for example. After that, the display A ″ in which the line type is changed is displayed, and there is a problem that the original display A and the changed display A ″ cannot be simultaneously displayed and compared. For this reason, it is desirable to display the multiple states as a multi-window and to compare them with each other while keeping the structure of the conventional graphics software that is only conscious of a single screen (window). It is rare.

The present invention solves these problems by
The display process can spawn a duplicate display process as needed to pass the current graphics code and display it in a window, effectively achieving multi-windowing without major changes to existing graphics software. Has an aim.

[0016]

[Means for Solving the Problems] Means for solving the problems will be described with reference to FIG. In FIG. 1, the display process 2 receives a graphics code, displays it on one window, and activates the duplicate display process 4 in response to a duplication instruction to pass the graphics code.

The duplicate display process 4 creates a new window and displays it based on the graphics code passed.

[0018]

According to the present invention, as shown in FIG. 1, the display process 2 receives a graphics code.
In addition to displaying on one window, in response to the duplication instruction, the duplication display process 4 is activated and the graphics code is passed, and the activated duplication display process 4 is passed by creating a new window. It is displayed based on the graphics code.

At this time, in the state where the display process 2 which has received the graphics code is displaying it on the window, the duplication display process 4 is activated in response to the duplication instruction and the graphics code currently being displayed is displayed. Pass the
The activated duplication display process 4 is displayed in a manner of duplication on a newly created window based on the passed graphics code.

Accordingly, the display process 2 activates the duplicate display process 4 as necessary, passes the current graphics code and displays it in the window, and effectively without changing the existing graphics software. It becomes possible to realize a multi-window.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the construction and operation of an embodiment of the present invention will be sequentially described in detail with reference to FIGS.

FIG. 1 shows a block diagram of an embodiment of the present invention.
In FIG. 1, a graphics data creation process 1
Is for creating a graph, sending a graphics code to instruct to display, or sending a clear graphics code to instruct to clear the screen.

The display process 2 displays on one window on the display 5 or moves / enlarges / reduces / reproduces the window based on the graphics code sent from the graphics data creation process 1. For example, the drawing is performed, the screen is cleared, the duplication display process 4 is activated in response to a duplication instruction, and the current graphics code is passed (described later with reference to FIG. 2).

The file 3 stores the graphics code currently displayed by the display process 2. The duplicate display process 4 is activated by the display process 2 and displays it on the newly created window based on the passed graphics code. The duplicate display process 4 is activated each time by the display process 2 in response to a duplicate instruction, and a plurality of duplicate presences are recognized at the same time.

The display 5 displays a plurality of windows. Next, the operation of the configuration of FIG. 1 will be described in detail according to the order shown in the flowchart of FIG.

In FIG. 2, S1 reads data. This reads the data to be displayed from a file not shown, and prepares to create a graph here.

In step S2, a graph is created. In S3, a display instruction is given. This is because the graphics data creation process 1 has a display instruction, as shown in an example of a graphics code in FIG. 3 to be described later, with "line display" set as a processing code and coordinate values set as parameters. Send the code to display process 2.

In S4, the display process 2 performs a display operation based on the graphics code sent in S3.
In S5, as the display A on the display 5, the solid line graph is displayed by the display operation of S4.

In S6, the graphics data creation process 1 changes the line type. In S7, the display process 2 receives the notification that the operator has pressed the copy button.

In step S8, the display process 2, which receives the copy button press notification in step S7, issues a copy instruction. S9 is
The display process 2 activates the duplicate display process 4.

In step S10, the graphics code currently displayed by the display process 2 is sent to the duplicate display process 4 started in step S9. In S11, the duplication display process 4 started in S10 creates a new window (display B here) on the display 5, and the data is displayed as shown in S12 based on the graphics code sent. Displayed in this window (display B), here a graph is displayed by a broken line.

In step S13, the graphics data creation process 1 sends a clear graphics code to the display process 2. In S14, a screen clear operation is performed. This causes the display process 2, which has received the clear graphics code sent in S13, to change the window (display A) to the clear display A '' as shown in S15. Either of the screen clearing of the window (display A) from S13 to S15 and the duplication operation from S7 to S12 may be performed first.

In S16, the graphics code creation process 1 gives a display instruction. This is because the graphics data creation process 1 sets “display line” as a processing code as a display instruction and sets coordinate values etc. in parameters. Here, a dotted line graphics code is sent to the display process 2. .

In step S17, the display process 2 performs a display operation based on the graphics code sent in step S16. In step S18, the display operation of step S17 is performed to display a dotted line graph as the display A ′ ″ on the display 5. As a result, the figure in which the line type has been changed is displayed in the cleared display A '', and the figure duplicated in the display B before the change is compared with the two, and the quality before and after the change is displayed in the multi-window (display A It is possible to make a judgment on the display B) as "".

In step S19, the end button is pressed. This is, for example, an end button (a QUIT of FIG. 4B, which will be described later) displayed on the window of the duplicated display B.
The operator presses a button) to instruct to end the duplicate display.

In step S20, the end operation is performed in response to the pressing of the end button in step S19. By this ending operation, the existing window is erased (data is also erased at the same time), and here, as shown in S21, the copy display B is displayed.
Is deleted, only the window (display A ′ ″) displayed by the display process 2 is displayed, and the series of operations for changing the graph from the solid line to the dotted line is completed.

As described above, when the graphics data creation process 1 instructs the display process 2 to display the window (display A) and the line type of the graph is changed, the operator performs S7. Corresponding to the pressing of the copy button at, the duplication display process 4 is activated, a new window (display B) is created, and the figure at this time is duplicated and displayed (display B of S12). And then display the modified graphics code Process 2
To display on the window (display A). As a result, the figure before change is displayed in the window (display B)
It is possible to judge whether the change is good or bad by displaying the changed figure on the window (display A ′ ″) and comparing the two. Then, in response to pressing the end button on the window (display B) before the change,
The duplicate display window (display B) is deleted.

The details will be sequentially described below. FIG. 3 shows an example graphics code of the present invention. This is created by the graphics data creation process 1 and displayed by the process 2.
When instructing to display on, it is for instructing to display on the window by specifying the following processing code and parameters. For example: -Processing code-01: Line display-02: Point movement-03: Screen clear-Parameters-Coordinate value-Graphics code that sets color information etc. is created and sent to the display process 2.

FIG. 4 is an explanatory diagram of generation of the copy display process of the present invention. (1) The display process 2 activates the duplicate display process 4 and duplicates the graphics code in response to pressing of the copy button by the operator or the like.
As a result, the duplication display process 4 is activated, and the currently displayed graphics code stored in the file 3 is displayed in the file 3 of the duplication display process 4.

(2) The duplication display process 4 started in (1) creates a new window and displays a figure in the window based on the graphics code extracted from the file 31.

(3) Similarly, the display process 2 activates the copy display process 4 and copies the graphics code in response to the copy button being pressed by the operator or the like. As a result, the duplication display process 4 is activated, and at the same time, the currently displayed graphics code stored in the file 3 is copied to the file 32 of the duplication display process 4 as the graphics code at the time of activation. Will be done.

(4) The duplication display process 4 started in (3) creates a new window and displays a figure in the window based on the graphics code extracted from the file 32.

As described above, the display process 2 activates the duplicate display process 4 each time the copy button is pressed, copies the graphics code currently displayed in the file, and activates the duplicate display. Process 4 creates a new window and displays a graphic based on the graphics code stored in the file. As a result, the display process 2 can create a large number of windows to display graphics and realize a multi-window.

FIG. 5 shows a replication explanatory diagram of the present invention. Figure 5
(A) shows an example of the COPY button (copy button). The COPY button is provided as "COPY" on the window in which the display process 2 displays a graphic or the like. In response to the operator pressing "COPY", as described above, the duplicate display process 4 is activated, the graphic code is passed, a new window is created, and the present figure is displayed.

The window display program 12 is shown in FIG.
The display process 2 corresponds to the display process 2. The notification of the graphics code from the main body program 11 to the window display program 1 is performed here by interprocess communication.

The redrawing graphics code 13 is the currently displayed graphics code stored in the file 3 of FIG. Copy display program 14
1 corresponds to the duplicate display process 4 in FIG. 1, and is started by the window display process 12 in response to the pressing of the copy button.

In the file 15, the window display program 12 at start-up has the graphics data 1 for redrawing.
It is a copy of 3. Based on the graphics code copied to this file 15, a process 14 for displaying a duplicate is displayed.
The figures are displayed in the newly created window.

The hard copy output program 16 prints the redrawing graphics data 13, and is started by the window display program 12. At this time, the redrawing graphics data 13 is copied to the file 17, and printing is performed based on the copied graphics code.

As described above, the graphics data (graphics code of FIG. 3) is sent from the main body program 11 having no multi-window function to the window display program 12 by interprocess communication, and the window display program according to the present invention is displayed. The program 12 activates the duplication display program 14 in response to the pressing of the copy button, passes the redrawing graphics data currently displayed, and creates a new window to display a figure or the like, or a hard copy. By starting the output program 16 and passing the redrawing graphics data that is currently displayed for printing, the conventional main body program 11 having no multi-window structure is left as it is, and the multi-window is effectively displayed. It can be realized.

FIG. 7 shows a display example of the present invention. this is,
According to the flowchart of FIG. 2, in addition to the window displayed by the display process 2 (display A), the copy button is pressed to display five copies at each time in the window (display B). As a result, the window (display A) and the plurality of duplicated windows (display B) can be compared with each other, and the contents of the window (display A) can be changed, and the multi-window can be efficiently used. .

[0054]

As described above, according to the present invention,
The display process 2 activates the duplicate display process 4 as needed, passes the current graphics code, and displays it in the window. Therefore, it is effective without making a large change to the existing graphics software. Multi-window can be realized. As a result, in the graphics software that does not have the concept of having a plurality of display devices at the same time, it is possible to effectively use the multi-window without changing the conventional software.

In particular, by separating the display process 2 from the graphics data creation process 1, without changing the conventional graphics software,
The multi-window can be realized only by enhancing the function of the display process 2 side, and it can be effectively used as follows.

(1) A plurality of graphs can be easily compared on the same workstation. (2) If you want to change the line type such as a line graph, first copy it and display it in a new window, then enter the line type change command and display it. You can easily compare and check the appearance of graphs due to the difference in the line type (difference in the parameters) without recreating.
