Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window display control device for selecting a corresponding window from a plurality of windows having a predetermined display area for an image and displaying the selected window on a display device, a method thereof, a storage medium and information. A processing device, a window display control device for performing display control for displaying a window and an icon arranged in the window on a display device, a method thereof, a storage medium and an information processing device, and a position on a display screen are designated. The present invention relates to an information processing apparatus for constructing a multi-window system having a position indicating means and capable of displaying a plurality of windows on a display screen, a method therefor, and a storage medium.

[0002]

2. Description of the Related Art In general, in an information processing apparatus, a multi-window system capable of displaying a plurality of windows having a predetermined display area for an image is constructed. In this multi-window system, a plurality of windows are superimposed on each other and displayed. In some cases, a technique for recognizing a window hidden by being superimposed on another window is employed.

One of the techniques for recognizing a window hidden by being superimposed on another window is a "computer device having a function of displaying a plurality of windows".
(JP-A-5-173743).

In the technique described in Japanese Patent Laid-Open No. Hei 5-173743, the "overwrite mode" and the "transparent mode"
The window is normally displayed by the "overwrite mode", and when searching for a window that is hidden by being overlaid on another window, the mode is changed to "transparent mode", and the window is hidden by being overlaid on another window By displaying the window so as to be visible through the other windows, all the displayed windows are made visible. For example, as shown in FIG. 31A, when the overwriting mode is designated by the icon I1 that designates the "overwriting mode" among the plurality of icons I1, I2, I3, and I4, the plurality of windows w1 , W2, w3,
w4 is superimposed and displayed. Of these windows, window w3 is superimposed on window w2 and hidden, and icon I3 is hidden by window w1.

When searching for a window that is hidden by being superimposed on another window, the mode is changed to "transparent mode" by the icon I2. With the mode change to the “transparent mode”, the display state of each window is as shown in FIG.
As shown in (b), a window w3 hidden and superimposed on the window w2 is displayed so as to be visible through the window w2, and an icon I3 superimposed and hidden on the window w1 is displayed via the window w1. The state is displayed so as to be visible, and the state is switched to a state where all the displayed windows and icons are displayed so as to be visible. As described above, it is possible to easily find the window w3 and the icon I3 which are superimposed and hidden by the “transparent mode”.

[0006] As another technique, "Information display method and information display apparatus" (Japanese Patent Application Laid-Open No. 8-195741).
Some are described in Japanese Unexamined Patent Publication No. Hei 8-1957
The technology described in Japanese Patent Application Publication No. 41 is to display a display expression (residual expression) of a residual object obtained by removing a background portion of a window (first object) to be superimposed, through the superimposed window. In the residual expression of the object, the outline of the object is performed by “expressing as an outline of a dotted line”.

For example, as shown in FIG. 32, when the windows 16 and 17 are superimposed on the window 15 on the digitizer input screen 14 provided on the display device 13 of the personal computer, they are hidden by the window 15. The windows 16 and 17 are displayed as dotted outlines, and the dotted outlines indicating the windows 16 and 17 are displayed through the window 15.

As still another technique, a C ++ drawing class library called InterViews implemented in an X window system is known. This technology adopts the concept of the transparency of a display object, prepares in advance several mask patterns corresponding to the transparency represented by a bitmap, and selects the patterns as appropriate to mask the corresponding objects. This realizes the display of a semi-transparent object. For example, as shown in FIG. 33, a mask pattern having a transparency of 50%, 70%, and 89% is given to each of the display objects 18, 19, and 20, and each of the display objects 18, 19, and 20 is provided.
By masking each of the display objects 20 with the corresponding mask pattern of transparency, each display object 18, 1 is masked.
The objects 9 and 20 are displayed in a semi-transparent manner, and an object hidden by being superimposed on another object can be recognized.

[0009]

However, the technique disclosed in the above-mentioned Japanese Patent Application Laid-Open No. Hei 5-173743 and the technique disclosed in Japanese Patent Application Laid-Open No.
According to the technology described in Japanese Patent No. 195741, since the windows superimposed on each other look visually the same, it is difficult to easily determine the vertical relationship between the windows.
In particular, when an object in each window is not recognized in advance, it cannot be easily identified which object belongs to which window.

In the C ++ drawing class library technology called InterViews, when objects having the same transparency mask pattern are displayed in a superimposed manner, these objects are masked by the same transparency mask pattern. Thus, the object superimposed by another object is completely hidden by this other object, and the recognition of the object superimposed by the other object becomes impossible.

SUMMARY OF THE INVENTION It is an object of the present invention to display not only an image contained in each window but also an image contained therein together with a plurality of windows so that the images contained therein can be easily visually identified when a plurality of windows are displayed in an overlapping manner. It is an object of the present invention to provide a window display control device, a window display control method, a storage medium, and an information processing device that can perform the operations.

Another object of the present invention is to provide a window display control device and a window display capable of easily managing multiple icons arranged on a window and improving the operability of the icons. It is to provide a control method, a storage medium, and an information processing device.

Still another object of the present invention is to provide an information processing apparatus, an information processing method, and a storage medium capable of improving operability in a window system capable of displaying a plurality of windows.

3 and a RAM 2. The CPU 1 constructs an OS by reading and executing an OS (Operating System) program stored in the ROM 3, and executes a corresponding application program on the OS using the RAM 2 as a work area.

Along with the OS program, a window display control program for selecting a corresponding window from a plurality of windows having a predetermined display area for an image and displaying the selected window on the CRT 7 is stored in the ROM 3 in a readable manner. I have.

This window display control program includes:
As shown in FIG. 2, a storage module 3a describing a process of storing the pixel components (red, green, green) constituting the image of each window and the transparency (t) corresponding to the pixel components in the RAM 2 is displayed on the CRT 7. When a window to be displayed with the image of the window being overlaid on the background image is selected as a background image, the pixel components constituting the foreground image overlapping the background image in the selected window and the transparency (t) thereof are read from the RAM 2.

Next, the principle of displaying a window using the transparency (t) by the above-described window display control program will be described with reference to FIGS. FIG. 4 is a diagram showing a correspondence relationship between pixel components constituting an image of a window displayed on the information processing apparatus of FIG. 1 and its transparency, and FIG. 5 is a window using the transparency (t) in the information processing apparatus of FIG. It is a figure showing the display principle of.

As shown in FIG. 4, the pixel components constituting the image of the window displayed on the CRT 7 are composed of red (r), green (g), and blue (b) color components. (T) is given. If the transparency of the window is uniform, t is given as a global parameter, and it is not necessary to give the transparency (t) for each pixel. The color components and the transparency (t) are stored in the RAM 2 as window attribute values for each window.

When a window to be displayed with the image of the window displayed on the CRT 7 superimposed on the background image is selected as a background image, as shown in FIG. 5, the foreground overlapping the background image in the selected window is selected. A color space vector Pf having a pixel component constituting an image, a transparency of the pixel component is represented by (t), a color space vector Pb having a pixel component of a background image, and each vector P
f and Pb are represented by Pf = (r, g, b) and Pb = (R, G, B).

By calculating a position vector P 'from the color space vector Pf to the color space vector Pb using the transparency (t) of the pixel component of the foreground image as a parameter, the position where the foreground image and the background image overlap is calculated. Is calculated. This position vector P 'is represented by P' = (R ', G', B ').

Here, in order to explain the general case, r, g, b, R, G, B and t all take real values in the range from 0 to 1, but in practice, It is often more convenient to multiply these by 255, which is one less than the number of tones, to obtain an integer value in the range from 0 to 255.

A position vector P 'is calculated from the color space vector Pf having the pixel components of the foreground image to the color space vector Pb having the pixel components of the background image, using the transparency (t) of the pixel components of the foreground image as a parameter. The calculation formula for this is expressed by the following formulas (1) and (2).

P ′ = (1−t) × Pf + t × Pb (1) (R ′, G ′, B ′) = (1−t) × (r, g, b) + t × Pb (R, G , B) (2) Here, if the transparency (t) is 0, that is, if the window serving as the foreground image is opaque, the expression (R ′,
G ′, B ′) = (r, g, b), and the window serving as the foreground image is completely overwritten regardless of the background image. Also, if the transparency (t) is 1, that is, if the window serving as the foreground image is transparent, then (R ′, G ′, B ′) = (R, G, B) from equation (2), and Window will not be displayed at all.

Therefore, by changing the transparency (t) in the range of 0 <t <1, the pixel component at the position where the foreground image and the background image overlap each other in consideration of the transparency (t) of the pixel component of the foreground image is obtained. Will be generated.

Next, a processing procedure by the above-described window display control program will be described with reference to FIGS. FIG. 6 is a flowchart showing a processing procedure by the window display control program in the information processing apparatus of FIG. 1, and FIG. 7 is a view showing an example of display of a window by the window display control program in the information processing apparatus of FIG. In this description, r, g, b, R,
G, B, and t take integer values in the range of 0 to 255.

When a window to be displayed with the image of the window displayed on the CRT 7 superimposed on the background image is selected, as shown in FIG. 6, first in step S1, the window to be superimposed is displayed. The position is obtained as (X, Y), the width is W, and the height is H, y = 0 in subsequent step S2, and x =
Set to 0. Here, the position (X, Y) is the starting point position of the area of the window to be overlaid, x is the unit increment in the width direction from the starting point position of the window,
y is a unit increment in the height direction from the start point of the window.

Then, the process proceeds to a step S4, wherein the position (X +
Each color component (R, G, B) of the pixel already displayed at (x, Y + y) is read, and at step S5, each color component (r) of the pixel corresponding to the position (x, y) of the window to be displayed from now on is read out. , G, b) and the transparency (t) associated therewith.

Then, the process proceeds to a step S6, wherein pixel components (R ', G', B ') at positions where the foreground image and the background image overlap are generated based on the above-described window display principle. Specifically, the following (3), (4),
Each pixel component (R ', G', B ') is calculated by equation (5).

R ′ = (255−t) × r + t × R (3) G ′ = (255−t) × g + t × G (4) B ′ = (255−t) × b + t × B (5) In the following step S7, the calculated color components (R ',
G ′, B ′) at the position (X + x, Y + y) on the VRAM 5
Write to.

Then, the process proceeds to a step S8, wherein the value of x is set to 1
Then, it is determined in step S9 whether the relationship of X + x ≦ W is established. When the relationship of X + x ≦ W is established, a region in the unit line extending in the height direction of the window to be overlaid and a region in the width direction and a region where the background image overlaps remain, and the process returns to step S4. It returns and repeats the processing from step S4.

If the relation of X + x ≦ W is not established, the unit line extending in the height direction of the window to be overlaid will not have an area where the area and the background image overlap in the width direction. Proceeding to S10, the value of y is incremented by 1, and in step S11, Y + y ≦
It is determined whether the relationship of H is established. When the relationship of Y + y ≦ H is established, an area in the height direction of the window to be overlaid is left with an area overlapping with the background image, and the process returns to step S3 again.
The processing from step S3 is repeated.

If the relationship of Y + y ≦ H is not established, there is no remaining area in the height direction of the window to be overlaid, which overlaps with the background image, and this processing ends.

For example, as shown in FIG. 7, when windows 22, 23, and 24 are sequentially superimposed and displayed on the root window 21, the pixels of the area of the window 21 overlapping the area of the window 22 are determined by the transparency (t) of the window 22. Are generated as pixel components having the parameters
Are generated as pixel components using the transparency (t) of the window 23 as a parameter, and the pixels of the windows 21, 22, and 23 that overlap the region of the window 24 have the transparency (t) of the window 24 as a parameter. It is generated as a pixel component, and the transparency (t) of the window is reflected on the background pixel every time a new window is superimposed. Therefore, the visibility of each overlapped window is not impaired, and each overlapped window can be easily recognized.

In this embodiment, the case where the transparency of the window to be overlapped is not uniform and the transparency (t) is given to each pixel has been described.
When the transparency of the windows to be overlapped is uniform, the transparency (t) is set in step S1 described above, so that the reading of the transparency (t) for each pixel in step S5 becomes unnecessary. It is also possible to do so.

In the present embodiment, the above-described display control program is stored in the ROM 3. However, instead of this, the display control program is stored in a hard disk, MO, FD, or the like.
The display control program may be stored in an external storage device such as D, and read out from the external storage device to the RAM 2 and executed when necessary.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 8 is a flowchart showing a processing procedure according to the window display control program in the second embodiment of the information processing apparatus of the present invention.

This embodiment is different from the first embodiment in that a displayable image is provided with a CRT in which a monochrome 16-tone image is provided, and the pixel components constituting each window have a gray level indicating an intermediate tone. This embodiment is different from the first embodiment in that the pixel of the foreground image read from the intermediate gray level of the pixel component of the read foreground image and the intermediate gray level of the pixel component of the read background image is determined by a predetermined operation. A proportional distribution value is calculated using the transparency (t) of the component as a parameter, and a gray scale component of the calculated proportional distribution value is set as a pixel component at a position where the foreground image and the background image overlap.
Note that the basic configuration in the present embodiment is the same as that in the above-described first embodiment, and a description of the configuration will be omitted.

Next, a processing procedure by the window display control program in the present embodiment will be described. Note that the window display control program according to the present embodiment is stored in the ROM 2 as in the above-described first embodiment, and the pixel g and the transparency (t) take integer values in the range of 0 to 15.

When a window to be displayed with the image of the window displayed on the CRT superimposed on the background image is selected as a background image, first, as shown in FIG.
In step 21, the position of the window to be overlaid is acquired as (X, Y), the width is W, and the height is H, and y = 0 in step S22 and x = 0 in step S23.

Then, the process proceeds to a step S24, wherein the position (X
The gray scale component G of the pixel already displayed at (+ x, Y + y) is read out, and in step S25, the gray scale component g of the pixel corresponding to the position (x, y) of the window to be displayed and the corresponding gray scale component g The read transparency (t) is read.

Then, the process proceeds to a step S26, wherein a gray scale component G 'at a position where the foreground image and the background image overlap each other is generated. Specifically, the gray scale component G 'is calculated by the following equation (6).

G ′ = (15−t) × g + t × G (6) In the following step S27, the calculated gray scale component G ′ is written to the position (X + x, Y + y) on the VRAM 5.

Then, the process proceeds to a step S28, where the value of x is incremented by 1, and in a succeeding step S29, it is determined whether or not the relationship of X + x ≦ W is established. When the relationship of X + x ≦ W is established, an area in the unit line extending in the height direction of the window to be overlaid and an area in the width direction and an area where the background image overlaps remain, and the process returns to step S24. Returning, the processing from step S24 is repeated.

If the relation of X + x ≦ W is not established, there is no remaining area where the area overlaps the background image in the width direction in the unit line extending in the height direction of the window to be overlaid. Proceeding to S30, the value of y is incremented by 1, and in the following step S31, Y + y ≦
It is determined whether the relationship of H is established. When the relationship of Y + y ≦ H is established, an area in the height direction of the window to be overlapped with the background image remains in the area in the height direction, and the process returns to step S23 again, and the processing from step S23 is repeated. repeat.

If the relation of Y + y ≦ H is not established, there is no remaining area overlapping the background image in the area in the height direction of the window to be overlaid, and this processing ends.

As described above, even when the pixel components forming each window are composed of gray scale components representing 16 intermediate gray levels, when a new window is superimposed, the transparency (t) of the window is increased. Since the reflected windows are reflected on the background pixels, the visibility of each overlapped window is not impaired, and each overlapped window can be easily recognized.

Referring to FIG. 14, first, at step S1
At 01, a process for detecting an input from the mouse 9 or the keyboard 10 is performed. This input includes coordinate data for detecting the area, and the input position of the command can be detected from the coordinate data.

Then, the process proceeds to a step S102, where it is determined whether or not the result of the input detection processing is an icon manager related command. If the detected result is not an icon manager related command, the process returns to the step S101 again, and the processing from the step S101 is repeated. Repeat.

If the result of the detection is an icon manager related command, the flow advances to step S103 to determine whether or not the icon manager related command is an attribute setting command. The process proceeds to a process (shown in FIG. 15), and if the icon manager related command is not the attribute setting command, the process proceeds to step S104.

In step S104, it is determined whether or not the icon manager-related command is a region division command. If the icon manager-related command is a region division command, the process proceeds to region division processing (shown in FIG. 16). If the icon manager related command is not an area division command, the process proceeds to step S105.

In step S105, it is determined whether or not the icon manager-related command is an icon generation command. If the icon manager-related command is an icon generation command, the process proceeds to icon generation processing (shown in FIG. 17). If the icon manager related command is not an icon generation command, the process proceeds to step S106.

In step S106, it is determined whether or not the icon manager related command is an end command.
If the icon manager related command is not the end command, the process returns to step S101 again,
Is repeated. If the icon manager related command is an end command, the process ends.

In the attribute setting process, as shown in FIG.
First, an attribute setting table (shown in FIG. 13) is displayed on the CRT 7 in step S111, and in the following step S112, title, name condition, time condition, and size condition attributes in the row or column direction of the icon arrangement area are input.

Then, the process proceeds to a step S113, wherein FIG.
The attribute setting is terminated by pressing the “setting end” key on the attribute setting table display screen shown in FIG. 6, and the process proceeds to step S114 in response to the icon arrangement area management processing execution interrupt issued upon completion of the attribute setting. Shift to area management processing.

In step S114, the icon arrangement area management table 85 (shown in FIG. 12) is updated based on the result of the setting using the attribute setting table. In step S115, it is determined whether the icon arrangement area has increased or decreased. I do. If there is an increase or decrease in the icon arrangement area, the process proceeds to step S116, and the icon arrangement area is changed to C by referring to the icon arrangement area management table.
It is displayed again on RT7. On the other hand, if there is no increase or decrease in the icon arrangement area, the process returns to step S101 (shown in FIG. 14), and the processing from step S101 is repeated.

In the area dividing process, as shown in FIG.
First, in step S121, an area division command is
It is determined whether or not a horizontal rule drawing command for dividing the window in the row direction is included. If the horizontal rule drawing command is included, the process proceeds to step S122 to draw a horizontal rule. Next, the process proceeds to step S123, where the number of rows is increased to increase the icon arrangement area in the row direction, and a transition to the icon arrangement area management processing (shown in FIG. 15) is performed by issuing an icon arrangement area management processing execution interrupt.

On the other hand, if the area dividing command does not include a horizontal ruled line drawing command, the flow advances to step S124 to draw a vertical ruled line, and in the subsequent step S125, the number of columns is increased to increase the icon arrangement area in the column direction. . Next, a transition to the icon arrangement area management processing is performed by issuing an icon arrangement area management processing execution interrupt.

In the icon generation process, as shown in FIG. 17, first, a new icon is generated in step S131. Since the icons are minimized windows,
It is under the control of the window system. Therefore,
When a new icon is generated, a memory area is newly secured as a tree-structured node of the window, similarly to a general window.

Then, the process proceeds to a step S132, where the shape of the icon is set. The shape setting of the icon is to set an image data file representing the display mode of the icon. In this shape setting, the image data file is automatically set according to the type of file, folder, device, or the like, or Set arbitrarily by the user.

Next, the process proceeds to step S133, where the name of the icon is set, and in step S134, the icon and the actual file are linked.

When the icon generation is completed in this way, it is necessary to display the generated icon on the CRT 7, and a transition to the area search processing is performed with the completion of the icon generation.

In the area search process, as shown in FIG.
First, in step S141, the attribute of the icon is obtained. Here, the attributes of the icon to be acquired are the name condition,
These are a time condition and a size condition indicating the generation time.

Then, the process proceeds to a step S142, wherein 1 is substituted for the line number I of the icon arrangement area and 0 is substituted for the variable K. This variable K is a number representing an area that meets the icon arrangement condition, and if the value is a value other than 1, it is processed as an error.

In a succeeding step S143, each condition (attribute) of row I of the icon arrangement area management table 85 is compared with the attribute of the icon, and each condition (attribute) of row I of the icon arrangement area management table 85 and the icon of the icon are compared. If the attributes match each other,
Proceeding to step S144, the value of the variable K is incremented by one, and the value of the row number I is incremented by one in step S145. In contrast,
If the conditions (attributes) of row I of the icon arrangement area management table 85 and the attributes of the icons do not match each other, step S1
Skipping to step S145, skipping to step S145
Is incremented by one.

After incrementing the value of the row number I by one, step S1
The process proceeds to 46, where it is determined whether or not the line number I is larger than the last line number. If the line number I is not larger than the last line number, the process returns to step S143, and the process returns to step S143.
Is repeated. When the line number I is larger than the last line number, the process proceeds to step S147, and it is determined whether or not the variable K is 1. When the variable K is 1, the process proceeds to step S148 (shown in FIG. 19) and the variable K If is not 1, the process proceeds to step S155 (shown in FIG. 19).

In step S148, as shown in FIG. 19, 1 is assigned to the column number J of the icon arrangement area, and the variable K
To 0. In a succeeding step S149, each condition (attribute) of column J of the icon arrangement area management table 85 is compared with the attribute of the icon, and each condition (attribute) of column J of the icon arrangement area management table 85 and the attribute of the icon are compared. If they match each other, the process proceeds to step S150, where the value of the variable K is incremented by one, and in the following step S151, the value of the column number J is incremented by one. On the other hand, if the conditions (attributes) in the J column of the icon arrangement area management table 85 and the attributes of the icon do not match each other, the process skips step S150 and proceeds to step S151 to increase the value of the column number J by one.

After incrementing the value of column number J by one, step S1
The process proceeds to 52, where it is determined whether or not the column number J is larger than the last column number. If the column number J is not larger than the last column number, the process returns to step S149 again, and the process returns to step S149.
Is repeated. If the column number J is larger than the last column number, the process proceeds to step S153, and it is determined whether the variable K is 1. If the variable K is 1, the process proceeds to step S154. If the variable K is not 1, the process proceeds to step S154. Proceed to S155.

In step S154, the icon placement area (I, J) is passed to the icon placement processing as a search result of the icon placement area, and the process shifts to the icon placement processing.

In step S155, the icon arrangement area (1,
The search result is passed to the icon arrangement processing as 1) as a search result of the icon arrangement area, and the process shifts to the icon arrangement processing.

In the icon layout processing, as shown in FIG. 20, first, in step S161, the icon layout area (I,
J) and the icon arrangement area management table 85 to acquire the icon arrangement coordinates.

Next, the process proceeds to step S162, where the position attribute of the icon is set based on the acquired coordinates of the position of the icon. Here, as described above, since the icon is obtained by minimizing the window, the icon needs an attribute to hold its position, similarly to the window, and this attribute is set as the icon position attribute. .

Next, the flow proceeds to step S163, where the icons are arranged in the icon arrangement area (I, J) passed as the search result of the area search processing and displayed on the CRT 7.

When the icon arranging process is completed in this way, the process returns to step S101 (shown in FIG. 14) again, and the process from step S101 is repeated.

As described above, the desired icons are automatically arranged in the tabular icon arrangement area obtained by dividing the window into the tabular areas, so that the icons can be easily managed and the icon management can be easily performed. Operability related to the arrangement of icons in the system can be improved.

(Fourth Embodiment) Next, a fourth embodiment of the present invention will be described with reference to FIGS. FIG. 21 is a diagram showing a display example of a schedule management table created by applying the icon management system in the fourth embodiment of the information processing apparatus of the present invention, and FIG. 22 is a fourth embodiment of the information processing apparatus of the present invention. FIG. 6 is a diagram showing a configuration of an icon arrangement area management table used for (1).

In the present embodiment, similarly to the third embodiment, an icon management system is constructed, and control for arranging and displaying icons in a schedule management table by applying the icon management system is performed.

For example, in the present embodiment, as shown in FIG. 21, in the window 121 representing the schedule management table, which is managed by the icon manager 80, the rectangular area excluding the window title area 122 is divided into horizontal ruled lines 123. Is divided into a plurality of icon arrangement areas 129 by the vertical ruled line 124 and each icon arrangement area 1
The titles 125 and 126 are assigned to the respective icons 29 to manage the respective icon arrangement areas 129, and the respective icons 127 are arranged in the corresponding icon arrangement areas 129.

As shown in FIG. 22, the icon arrangement area management table for managing the icon arrangement areas in the schedule management table shows the icon arrangement areas obtained by dividing the window in the rows and columns. It comprises an icon arrangement area number for dividing in the direction, a display area of each icon arrangement area, a title of each icon arrangement area, and attributes of a name condition, a time condition, and a size condition.

When arranging the icons corresponding to the respective icon arrangement areas of the schedule management table, for example, the icons of “camp” in the first week are changed to “regular meetings” every Friday.
When the icon of “section” is arranged on the second Monday of each icon, an attribute setting table is displayed and an attribute for each icon arrangement area is input, as in the third embodiment. For example, since a row represents the first to the fourth week, if the time condition is December 1996, “12/1
Since the date is input as "-12/7" and the column indicates the day of the week, assuming that the day number indicating Sunday is "(0)", "(0)" is input on Sunday as a time condition. Is done. By inputting this attribute, the above-described icon arrangement area management table shown in FIG. 22 is updated. Since a plurality of attributes are managed by the icon arrangement area management table obtained in this manner, unlike the conventional case where icons are arranged based on the time (date) simply designated as the attribute of the icon, the plurality of attributes are different. The icons corresponding to the respective icon arrangement areas can be arranged by using the attributes of (1), and a schedule management table capable of more diversified management can be easily created.

(Fifth Embodiment) Next, a fifth embodiment of the present invention will be described with reference to FIGS. FIG. 23 is a block diagram showing a main part configuration of a fifth embodiment of the information processing apparatus of the present invention, FIG. 24 is a view showing a display example of a window in the information processing apparatus of FIG.
5 is a diagram showing a configuration of a table of a multi-window system in the information processing device of FIG. 23, FIG. 26 is a diagram showing a program management state of a schedule queue in the information processing device of FIG. 23, and FIG. FIG. 3 is a diagram showing a memory map for constructing a window system.

This embodiment is an information processing apparatus having a position designating means for designating a position on a display screen and constructing a window system capable of displaying a plurality of windows on the screen.

More specifically, as shown in FIG. 23, the information processing apparatus has a mouse 9 and a keyboard 10 for indicating a position on the screen of the CRT 7 and a window capable of displaying a plurality of windows on the screen. System 201
Is building.

The window system 201 includes, for each window, a window-program table (hereinafter referred to as a table) 208 in which the window and a corresponding program are described in association with each other, and a CRT 7 designated by the mouse 9 or the keyboard 10. A coordinate reading unit 205 for reading a coordinate position on the screen, a schedule changing unit 207, and a display control unit 206 are provided.

As shown in FIG. 25, in the table 208, the window number of the window displayed on the CRT 7 and the name of the program running on the window, that is, the program being executed, are described in association with each other. .
The window number is, for example, a number assigned in ascending order when the window is generated. When the window disappears, the window number and the program name associated therewith are deleted from the table 208.

[0146] The schedule changing means 207
Alternatively, the operation priority of each window displayed on the screen of the CRT 7 indicated by the keyboard 10 is assumed in accordance with the coordinate position on the screen, and the operation priority of each window assumed with reference to the table 208 is followed. To CRT7
Is instructed to change the execution schedule of the program corresponding to each window displayed on the screen. In particular,
The schedule changing unit 207 is configured to change one of the windows.
When one window is designated by the mouse 9 or the keyboard 10, the operation priority of the one window is assumed to be the highest. For example, as shown in FIG. 24, each window 2 displayed on the screen of the CRT 7
When the window 211 among 11, 212, and 213 is designated by the cursor 214 indicating the designated position such as the mouse 9, the window 211 is assumed to have the highest operation priority of the window. An instruction is given to change the execution schedule of the program corresponding to each window displayed on the screen of the CRT 7 according to the assumed operation priority of each window.

The display control means 206 captures the coordinate position on the screen of the CRT 7 via the schedule changing means 207, displays a cursor at the captured coordinate position, and controls the display of the corresponding window.

The instruction to change the execution schedule of the program issued from the schedule changing means 207
Nine schedule queues 210, and the schedule queue 210 changes the execution priority of the program in response to an instruction to change the execution schedule of the program. The execution priority of the program changed in the schedule queue 210 is given to the scheduler 211, and the scheduler 211 gives the execution right of each program to a CPU (not shown) according to the changed execution priority of the program. For example, in the schedule queue 210, FIG.
As shown in (1), execution priorities are given to programs to manage the execution order of the programs. In this example, since the program “CC” is located at the head, the execution right of the program “CC” is given to the CPU by the scheduler 211.

Such a window system 201
It is constructed by reading and executing a multi-window program stored in a ROM (not shown). As shown in FIG. 27, this multi-window program stores a table 208 in a table storage area 2 for storing a table 208.
08a, a coordinate reading processing module 205a for constituting the coordinate reading means 205, and a schedule changing means 2
07, and a display control processing module 206a for configuring the display control means 206.

Next, a processing procedure in the information processing apparatus will be described with reference to FIG. FIG. 28 shows FIG.
6 is a flowchart showing a processing procedure in the information processing apparatus of FIG.

Referring to FIG. 28, first, at step S20
In step 1, the coordinates of the cursor 214 are read.

Then, the flow advances to step S202 to perform a process for determining which of the windows displayed on the CRT 7 the cursor 214 indicates based on the read coordinates of the cursor 214. Assuming that the window designated by the cursor 214 has the highest operation priority of the window, the program executed on the window is recognized with reference to the table 208.

Next, the process proceeds to step S204, where the execution priority of the program having the recognized program name is set to the highest priority, and in the next step S205, the schedule queue 210 is set so that the program is set at the head.
To instruct.

As described above, when one of the windows displayed on the screen of the CRT 7 is designated by the mouse or the like, the operation priority of the one window is assumed to be the highest priority, Since the schedule queue 210 is instructed to change the execution schedule of the program corresponding to the window displayed on the screen of the CRT 7 so as to follow the operation priority of the window assumed with reference to the table 208, The above program can be executed with higher priority than the programs on other windows, and operability in a window system capable of displaying a plurality of windows can be improved. Further, the present window system can be easily constructed without making significant changes to existing information processing apparatuses.

(Sixth Embodiment) Next, a sixth embodiment of the present invention will be described with reference to FIGS. FIG. 29 is a diagram showing a display example of a window in the sixth embodiment of the information processing apparatus of the present invention, and FIG. 30 is assumed according to the display state of the window in the sixth embodiment of the information processing apparatus of the present invention. It is a figure showing an example of operation priority of a window.

This embodiment is different from the fifth embodiment in that, when a plurality of windows are displayed on the screen of the CRT 7, the operation priority of each window is changed according to the display state of each window. CRT so as to follow the operation priority of each window assumed by referring to the table
7 in that an instruction to change the execution schedule of the program corresponding to each window displayed on the screen 7 is provided.

[0157] Specifically, when a window displayed on the CRT 7 overlaps with a window displayed on the CRT 7 and a window independently displayed on the screen, the frontmost one of the windows displayed on the CRT 7 overlaps with each other. It is assumed that the respective operation priorities of the window displayed in the window and the window displayed independently are the highest priority.
