DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a block diagram showing the overall configuration of the data processing apparatus.
The CPU 1 is a central processing unit that controls the overall operation of the data processing device according to various programs. The storage device 2 includes a storage medium 3 in which an operating system, various application software, a database, character font data, and the like are stored in advance, and a drive system thereof. The storage medium 3 is fixedly provided or detachably mountable, and is constituted by a magnetic / optical storage medium such as a floppy disk, a hard disk, an optical disk, or a RAM card, and a semiconductor memory. The program and data in the storage medium 3 are loaded into the RAM 4 under the control of the CPU 1 as necessary. Further, the CPU 1 receives a program and data transmitted from another device via a communication line or the like and stores them in the storage medium 3 or stored in a storage medium provided on the other device. Existing programs and data can be used via a communication line or the like. An input device 5 and a display device 6 which are input / output peripheral devices are connected to the CPU 1 via a bus line, and the CPU 1 controls their operations in accordance with the input / output program.
The input device 5 has a pointing device such as a keyboard or a mouse for inputting character string data or inputting various commands. The display device 6 is a liquid crystal display device, a CRT display device, a plasma display device, or the like, and a display screen having a different aspect ratio can be switched as a vertical screen installed in a vertically long state or a horizontal screen installed in a horizontally long state. Yes. Here, in this embodiment, two types of screen formats are not prepared for the vertical screen and the horizontal screen, but other screen formats are created based on one type of screen format.
[0007]
FIG. 2 shows a part of the storage device 2, and the reference format table 2-1 stores the preset horizontal width and vertical width of the reference screen as a reference screen format. A) shows the data structure of the reference format table 2-1. Here, in this embodiment, the reference screen is based on a 12-inch horizontal screen (maximum screen), and the maximum horizontal width X0 and the maximum vertical width Y0 are used as the reference size (physical size). In addition, a reference font size F and a minimum font size Fmin are stored as character font sizes. Here, the chart shown on the right side of FIG. 3 shows specific numerical values of various data. This horizontal screen is a screen having a maximum horizontal width size X0 of “800” and a maximum vertical width size Y0 of “600”. The reference size of the character font displayed in the screen is “12” points, which indicates that it can be reduced to a minimum of 8 points.
The current screen information table 2-2 stores current screen information indicating the current screen state acquired from the display device 6, and FIG. 3B illustrates the contents of the current screen information table 2-2. . Here, if the current screen state is a 12-inch horizontal screen, the current screen width X01 and the current screen vertical width Y01 are set. If the current screen state is a 12-inch vertical screen, the current screen width X01 and the current screen vertical width are set. Y01 is set.
[0008]
The screen format file 2-3 defines the screen format for the reference screen for each application. In addition to defining the display position and display size for each object such as the title area, text input area, and control area, Defines the character font size etc. displayed in the object. In the figure, the detail column start point, detail row start point, detail column end point, and detail row end point set corresponding to the user detail area define the display position and display size of the user detail area. Similarly, the start point position (XY coordinate) and end point position (XY coordinate) set corresponding to the group control display area define the display position and display size of the control area. In addition to the font size of each object, character modification information is also defined.
FIG. 15 shows a display example when a 12-inch horizontal screen is designed as a reference screen for an application. The application screen is designed so that the maximum display using the entire horizontal screen is achieved. FIG. 6 shows this horizontal screen. Is a display example when the screen is switched to a 12-inch vertical screen. Here, each object is expanded / compressed in accordance with the maximum screen so that the maximum display using the entire screen can be obtained on the vertical screen as well as the horizontal screen. In this case, when switching from the horizontal screen to the vertical screen is instructed, based on the horizontal size and vertical size of the reference screen (horizontal screen) and the horizontal size and vertical size of the current screen (vertical screen) Thus, the horizontal width expansion ratio and the vertical width expansion ratio of the current screen with respect to the reference screen are obtained, a current screen format in which the current screen size is changed based on the expansion ratio is generated, and the current screen display is performed according to the generation format.
[0009]
Next, the operation of this data processing apparatus will be described with reference to the flowchart shown in FIG. Here, a program for realizing each function described in this flowchart is stored in the storage medium 3 in the form of a readable program code, and the CPU 1 sequentially executes operations according to the program code. . The same applies to other embodiments described later.
FIG. 7 is a flowchart showing display control when the display screen is spun.
First, the CPU 1 accesses the reference format table 2-1, and acquires the reference screen size (step A1). In this case, the reference screen is a 12-inch horizontal screen, and the horizontal width reference size X0 “800” and the vertical width reference size Y0 “600”, which are the maximum screen width, are acquired. Next, the current screen size is acquired by accessing the current screen information table 2-2 (step A2). In this case, since switching to the vertical screen is instructed, the current screen width X01 “600” and the current screen vertical width Y01 “800” are obtained from the current screen information table 2-2 as the size information of the 12-inch vertical screen. . Then, the horizontal width expansion ratio and the vertical width expansion ratio are calculated based on the size information of the reference screen and the size information of the current screen (step A3). That is, the horizontal width expansion ratio Xx and the vertical width expansion ratio Yx of the current screen with respect to the reference screen are calculated according to the following equations. Width expansion ratio Xx = Horizontal width of current screen (X01) ÷ Horizontal width of reference screen (X0), Vertical expansion ratio Yx = Vertical width of current screen (Y01) ÷ Vertical width of reference screen (Y0)
Here, since the reference screen has the horizontal width reference size X0 = 800 and the vertical width reference size Y0 = 600, when spinning from the horizontal screen to the vertical screen, Xx = X01 ÷ X0 = 600 ÷ 800 = 0.7500, Yx = Y01 / Y0 = 800/600 / = 1.3333. Further, when spinning from a vertical screen to a horizontal screen, Xx = X01 ÷ X0 = 800 ÷ 800 = 1.0000 and Yx = Y01 ÷ Y0 = 600 ÷ 600 = 1.0000.
[0010]
After obtaining the horizontal width expansion ratio Xx and the vertical width expansion ratio Yx of the vertical screen with respect to the horizontal screen in this way, the CPU 1 accesses the screen format file 2-3 and reads the data from the head object (step A4). It is checked whether there is an object (step A5). Here, if there is an object, the start point (X1, Y1) and end point (X2, Y2) coordinates corresponding to the object are taken in, and the horizontal width expansion rate and the vertical width expansion rate are set in the X component and Y component of the start point coordinate, respectively. By multiplying, new start point coordinates (NX1, NY1) and end point coordinates (NX2, NY2) are obtained (step A6). That is, the start point and end point defining the display position and size of the object on the vertical screen are calculated by calculating NX1 = X1 * Xx, NY1 = Y1 * Yx, NX2 = X2 * Xx, NY2 = Y2 * Yx. Generate as screen format.
[0011]
Next, whether or not there is character data in the object is checked by referring to the screen format file 2-3 (step A7). If not, the process returns to step A4 to specify the next object. Then, the font size is changed (step A8). That is, the CPU 1 accesses the reference format table 2-1, reads the reference font size F (12 points), and converts the font size by multiplying the reference font size F by the horizontal width expansion rate Xx or the vertical width expansion rate Yx. Do. In this case, when the horizontal width expansion ratio Xx ≦ the vertical width expansion ratio Yx, a new font size NF is obtained by multiplying the reference font size F by the horizontal width expansion ratio Xx, but the horizontal width expansion ratio Xx> the vertical width expansion ratio Yx. In this case, a new font size NF is obtained by multiplying the reference font size F by the vertical width expansion rate Yx. Thereafter, returning to step A4, the above-described operation is sequentially repeated for each object. If the end of the object is detected in step A5, the process proceeds to step A9 to redraw each object. Thereby, switching from the horizontal screen shown in FIGS. 5 and 6 to the vertical screen and from the vertical screen to the horizontal screen is performed.
[0012]
If the value NF falls below the lower limit limiter Min defined in the standard format table 2-1, as a result of multiplying the width expansion ratio Xx by the font size F, NF = Min, and Xx = NF / F It may be modified so that each object is recalculated. In this case, the portion that protrudes from the screen may be scrolled as usual.
[0013]
As described above, in the first embodiment, when the horizontal width size and vertical width size of the reference screen are set in advance as the reference screen format, the horizontal width size and vertical width size of the current screen and the horizontal width size of the reference screen Based on the vertical size, obtain the current screen width expansion ratio and vertical width expansion ratio relative to the reference screen, and generate the current screen format by changing the current screen size and the character font size in the current screen based on the vertical and horizontal expansion ratio. Since the current screen is displayed according to this generation format, it is possible to respond to the orientation of the current screen by designing only one type of screen format regardless of whether the current screen is a vertical screen or a horizontal screen. Display is possible. Therefore, it is not necessary to prepare a plurality of screen formats according to the orientation of the screen, and the man-hour for application design can be greatly reduced, and customization thereof is also advantageous. In addition, since the reference screen is designed based on the maximum screen of a 12-inch horizontal screen, the vertical screen uses the entire screen even when the application screen is switched from the horizontal screen to the vertical screen. Maximum display. In addition, since characters and objects in the current screen are also changed according to the expansion rate, each object and font size can be expanded to the same size as the current screen. That is, as shown in FIG. 8, in a 12-inch horizontal screen with an aspect ratio of 3: 4, an object area has start point coordinates (10, 10), end point coordinates (50, 12), and font size 12P. When it is switched to the vertical screen, the object becomes the start point coordinates (7.5, 13.2), the end point coordinates (37.5, 16), and the font size 9P. It is expanded by the same magnification.
(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. In the first embodiment described above, the vertical and horizontal expansion ratios are obtained and expanded when switching between the vertical screen and the horizontal screen. In the second embodiment, the display screen currently in use is used. When the resolution of the application is changed, the application screen is expanded at the same magnification in the vertical and horizontal directions according to the resolution.
FIG. 9A shows the reference format table 2-11. The reference format table 2-11 stores the horizontal resolution X0pt and the vertical resolution Y0pt of the reference screen as the reference screen format. Like the above-described first embodiment, the reference screen is a 12-inch horizontal type of a predetermined application screen. Based on the screen (maximum screen), its resolution is the same as its horizontal size and vertical size. In the reference format table 2-11 of this embodiment, font sizes (reference font size F, reduced font size Fmin) are also stored. FIG. 9B shows the standard format table 2-12, which stores the current screen resolution acquired from the display device 6. If the current screen is a 12-inch horizontal screen, the horizontal resolution X1pt is stored. If the vertical resolution Y1pt is a vertical screen, the horizontal resolution X1pt is the vertical resolution Y1pt. Similarly, if the screen is a 14-inch horizontal screen, the horizontal resolution X1pt is vertical. If the vertical resolution Y1pt is a vertical screen, the horizontal resolution X1pt is The vertical resolution Y1pt is set in the current screen information table 2-12. Note that the screen format file 2-3 described above is also provided in the second embodiment.
[0014]
Next, the operation of the second embodiment will be described with reference to the flowchart shown in FIG. FIG. 10 is a flowchart that starts when the screen resolution is changed. First, the horizontal resolution X0pt and the vertical resolution Y0pt are obtained from the reference format table 2-11 (step B1), and the current screen information table 2-12. To obtain the horizontal resolution X1pt and the vertical resolution Y1pt of the current screen (step B2). Here, on condition that X0pt ≠ X1pt or Y0pt ≠ Y1pt is not satisfied (step B3), the process proceeds to a process of calculating the horizontal width expansion ratio and the vertical width expansion ratio of the current screen (step B4). It is executed on the condition that the screen is changed to another screen having a different horizontal resolution or vertical resolution. First, the current screen width expansion ratio Xx = current screen horizontal resolution X1pt ÷ reference screen horizontal resolution X0pt, the current screen height expansion ratio Yx = current screen vertical resolution Y1pt ÷ reference screen vertical resolution Y0pt is calculated. Thus, the expansion rates Xx and Yx are obtained (step B4). Thereafter, as in the first embodiment, the object data is read from the screen format file 2-3 (step B5). If there is an object (step B6), the start point (X1, Y1) and end point (X2, By multiplying Y2) by the expansion rates Xx and Yx, new start points (NX1, NY1) and end points (NX2, NY2) are obtained (step B7). If there is a character in the object (step B8), a process of changing the font size according to the expansion rate is performed (step B9). When the same processing is performed on all objects in this way, each object is redrawn (step B10).
[0015]
FIG. 11 shows a display example in this case. FIG. 11A shows a 12-inch vertical screen, and FIG. 11B shows a 14-inch vertical screen. Here, even when the 12-inch vertical screen is changed to the 14-inch vertical screen, or when the 14-inch vertical screen is changed to the 12-inch vertical screen, the maximum display using the entire screen is obtained. As shown in FIG. 12, the object and font size in the screen are also expanded at the same magnification in the vertical and horizontal directions. Although not shown, this is exactly the same between a 12-inch horizontal screen and a 14-inch horizontal screen.
As described above, even in the second embodiment, it is only necessary to design one screen format without preparing a plurality of screen formats, so that the design man-hours for the application can be greatly reduced. In addition to the advantage of customization, the maximum display is possible even if the screen resolution is changed, and the size of each object and character font in the screen can be expanded by the same magnification.
(Third embodiment)
Hereinafter, a third embodiment of the present invention will be described with reference to FIGS.
This third embodiment is a combination of the first embodiment and the second embodiment described above, and only when a single reference screen format is designed and the screen is spun into a horizontal screen or a vertical screen, Even if the resolution is changed, the screen can be converted accordingly. In this case, the reference format table 2-21 can set the reference size (horizontal width reference size X0, vertical width reference size Y0) and resolution (horizontal resolution X0pt, vertical resolution Y0pt) as shown in FIG. That's fine. Also in the current screen information table 2-22, as shown in FIG. 13B, the current screen horizontal width X01, the current screen vertical width Y01, the horizontal resolution X1pt, and the vertical resolution Y1pt can be fetched from the display device 6 and set. That's fine. Since the display control in the third embodiment is the same as that in the first and second embodiments described above, this flowchart is omitted. In this third embodiment, in addition to the screen conversion process associated with the screen spin, Then, a screen conversion process accompanying the resolution change is performed.
FIG. 14 is a diagram showing a screen conversion state in the third embodiment, and a mutual change between a 12-inch horizontal screen and a 14-inch vertical screen and a mutual change between a 12-inch vertical screen and a 14-inch horizontal screen are possible. Become.
(Fourth embodiment)
Hereinafter, a fourth embodiment of the present invention will be described with reference to FIGS. 15 and 16. This fourth embodiment shows screen conversion during screen spinning as in the first embodiment, and is basically the same as the first embodiment described above, but in addition to that, a specific object (detailed area) The number of detail lines in is controlled when the screen is spun.
FIG. 15 is a flowchart which is started when the screen is switched from the horizontal screen to the vertical screen. The horizontal width reference size X0 and the vertical width reference size Y0 of the reference screen are acquired from the reference format table 2-1 (step C1). Then, the current screen horizontal width X01 and the current screen vertical width Y01 of the current screen are acquired from the current screen table 2-2 (step C2). In this case, as in the first embodiment, the reference screen is based on a 12-inch horizontal screen, and the expansion ratio of the vertical screen is obtained with respect to this reference screen (step C3). The horizontal width expansion rate Xx is obtained by the calculation of Xx = X01 ÷ X0 as in the first embodiment described above, but the vertical width expansion rate Yx is fixed to “1”.
[0016]
Then, in the next step C4, in accordance with the switching from the horizontal screen to the vertical screen, the vertical coordinate conversion of the header area object, the total area object, and the total area object (the Y component start point and end point coordinate conversion) is performed. A process for increasing the number of lines in the detail area is performed. In this case, the horizontal width of the header area and the total area of the horizontal screen is not changed, the header area is allocated according to the top edge of the vertical screen, and the total area is allocated according to the bottom edge of the vertical screen. Therefore, the vertical width of the detail area allocated between the header area and the total area on the vertical screen is larger than that of the horizontal screen. That is, as shown in FIG. 16, when the vertical width of each object in the screen is specified by the Y coordinate components Y10, Y11, Y12, and Y13 of the horizontal screen, each object of the horizontal screen is displayed as the vertical screen. When assigned to Y, the Y coordinate component of each object on the vertical screen is Y20, Y21, Y22, Y23 (Y2x). Here, the coordinate conversion of the detail area object is performed by Y11 = Y21, Y22 = Y23− (Y13−Y12), and the coordinate conversion of the total area object is performed by Y22 = Y2x− (Y13−Y12), Y23 = Y2x.
Here, if Y13 = 600 and Y23 = 800, and Y11 = 100 and Y12 = 500, then Y21 = Y = 100, Y22 = Y23− (Y13−Y12) = − (600−500) = 700. Become. Therefore, the vertical width of the detail area object becomes 700-100 = 600 by Y22-Y21. In this case, if the height Ya per detail line is assumed, the number of detail lines is obtained by (Y22−Y21) ÷ Ya.
[0017]
Then, the object data is read from the screen format file 2-3 (step C5). If there is an object (step C6), the start point and end point coordinates of the area object are converted (step C7). In this case, similarly to the first embodiment described above, the start point (NX1, Y1) on the vertical screen is obtained by multiplying the start point (X1, Y1) and end point (X2, Y2) by the horizontal width expansion rate Xx and the vertical width expansion rate Yx. NY1) and end point (NX2, NY2) are obtained. In this case, since the vertical width expansion rate Yx is fixed to “1”, the vertical width of the area is not changed, and only the horizontal width is reduced according to the horizontal width expansion rate. Is done. Here, the start point coordinates of the detail area are NY1 = Y11, and the end point coordinates of the total area are NY1 = Y22. Further, the end point coordinates of the detail area are NY2 = Y22, and the end point coordinates of the total area are NY2 = Y23. If a character is included in the object (step C8), the font size is converted. In this case, the size is converted by the calculation formula of NF = F * Xx. Is reduced (step C9). When the conversion of each object is thus completed, the process proceeds to step C10. If there is a detail area object, the number of detail lines is determined based on the number of detail lines obtained in step C4 and the height Ya per detail line. A new detail line is automatically generated. In other words, the horizontal width of the detail area object is reduced according to the expansion ratio, but the vertical width is specified by the start point Y21 and the end point Y22 and is expanded more than the vertical widths Y11 and Y12 of the horizontal width screen. New detail lines are additionally generated for the number of lines corresponding to the number of lines. Note that the height of each detail line is the same for both the horizontal screen and the vertical screen. Then, each object is redrawn (step C11).
[0018]
As described above, the fourth embodiment has the same effects as those of the first embodiment described above, and the number of detailed lines that can be displayed on the screen is limited due to physical restrictions on the screen. By changing the screen to a vertical screen, the number of detailed lines can be increased significantly, and even if the amount of information increases accordingly, it is not necessary to scroll the screen, and improvement in workability can be expected.
In the above example, the number of detail lines is increased when switching from the width screen to the portrait screen. However, when the screen is switched from the portrait screen to the landscape screen by the same method, the detail area is changed. The number of column items may be increased. Further, it goes without saying that the same applies even when switching from a 12-inch horizontal screen to a 14-inch vertical screen or from a 12-inch vertical screen to a 12-inch horizontal screen.
FIG. 17 shows another display example. In this example, the detail lines are increased by 8 lines before and after the screen switching.
[0019]
