An embodiment of the present invention will be described in detail with reference to the drawings of FIGS.

FIG. 1 is a block diagram showing a schematic configuration of a chart editing apparatus according to the present invention.

In the figure, a keyboard / mouse control unit 11 controls input of various data, commands and the like from a keyboard 12 and a mouse 13 connected to the keyboard 12.

A central processing unit (hereinafter, referred to as a “CPU”) 14 executes a keyboard / mouse control unit 11, a disk control unit 15, a display control The control section 17 and other control sections and the real memory 19 are collectively time-divisionally controlled, and execute predetermined calculations and processes including display control of an array of items and windows according to the present invention.

The disk device 16 stores display data (contents,
Width, height, number, etc.), window display data (maximum,
(Minimum width and height) and data of the contents of the message displayed in the window. The disk control unit 15 controls the disk device 16 to read and write the data. .

The real memory 19 stores various execution programs including a data and item array from the disk device 16 and a program for controlling display of windows, and the CPU 14 performs various controls based on the execution programs on the real memory 19. ing.

The display control unit 17 controls a display device 18 such as a CRT based on the control of the CPU 14 to display items, windows, messages, and the like.

Next, the display control operation of the display control device for items and windows will be described with reference to the flowcharts of FIGS.

FIG. 2 and FIG. 3 show an item display control operation. When a user gives an instruction to display each item using the keyboard 12 or the mouse 13, the CPU 14 firstly sets the number of items (Inu).
mber), maximum width (Imaxwidth), maximum height (Imaxheigh
t) is initialized to 0 (step 101). Next, one item of display data is read from the real memory 19 (step 102), and it is determined whether or not all items of display data have been read (step 103).

Here, since the display data of all the items has not been read yet, the process proceeds to step 104 to add one to the number of items (step 104), and measures the width of the item based on the read display data of the item (step 104).
105). Then, it is determined whether or not the width (Iwidth) of the item is larger than the maximum width (Imaxwidth) of the item (step 106).

Here, the width of the above item (Iwidth) is the maximum width (Imax
If it is larger than (width), the width of the item is set to the maximum width of the item (step 107), and then the height (Iheight) of the item is measured based on the display data of the item (step 108). If the width of the item is smaller than or equal to the maximum width, the process directly proceeds to step 108 to measure the height of the item. And the height of the above item (Ih
eight) is the maximum item height (Imaxheight) (step 109).

Here, if the height (Iheight) of the item is higher than the maximum height (Imaxheight), the height of the item is set to the maximum height of the item (step 110), and the process returns to step 102 to return to the next step. The display data of the item is read, and the above operation is repeated. If the height of the item is lower than or equal to the maximum height, the process directly returns to step 102 to read the display data of the next item, and repeats the above operation. Then, when reading of the display data of all items is completed in step 103, the control operation proceeds to FIG.

FIG. 3 is a flowchart in which the items are arranged in a square close to the screen of the display device 18.
In the figure, an array of items is calculated based on the number of items, the maximum width and the maximum height. Or Therefore, seeking a route item number / (maximum width / maximum height) First, the obtained value as M ₁ (step 111), further to portrait the array of items of the menu to be displayed, Horizontal Or the above value to determine the number of columns of items
The value M ₂ truncating the decimal point M _1, obtaining the value M ₃ which carry a decimal point (step 112). Next, it is determined whether both the values M ₂ and M ₃ obtained above are 0 (step 113).

Here, if the values M ₂ and M ₃ are both 0, it is determined that there is an error in the arithmetic operation (step 114). If the values M ₂ and M ₃ are not 0, only the value M ₂ Is determined to be 0 (step 115).

Here, when only the above value M ₂ is 0, the value M ₃ that the number was moved up horizontally above a row of menu items (step 116). If the value M ₂ is not 0, M ₂ and M ₃
It is determined whether or not the values are equal (step 117).

Here, when the value of M ₂ and M ₃ are equal, because the sequence of menu items is a square, the number of columns of items and M ₂ (step 118). In the above case, M
Since ₂ and M ₃ are equal, the number of columns of items may be M _3. Further, when the value of M ₂ and M ₃ are not equal, M ₂ or M ₃
To determine which array is closer to a square,
Wherein the value M of - {maximum width of the item × M ₂ largest item height × value of carry decimal (number / M ₂ items)}
_4, {maximum width of the item × M ₃ - maximum height × Item
Finding the value M ₅ from the equation decimal point advance value} in (item number / M ₃₎ of (step 119). Next, it is determined whether a value M ₅ ≧ M ₄ was determined from the two formulas (step 120).

Here, if the value M ₅ ≧ M ₄ is the number of columns of the menu item and the value M ₂ of the portrait (step 121). Also, if not the value M ₅ ≧ M ₄ is the number of columns of the menu item as the value M ₃ in the horizontally long (step 122), and ends the operation.

Thereby, each item of the menu is displayed on the entire screen of the display device 18 in an array having a shape close to a square.

Therefore, according to the present invention, the arrangement of the menu items is calculated and the display is controlled so as to have a shape close to a square which is the shape of the screen of the display device, so that the listability of the menu can be improved.

FIG. 4 shows a window display control operation. When a user gives an instruction to display a message using the keyboard 12 or the mouse 13, the CPU 14 is first set in advance from the display device 18 and the real memory 19. Minimum width of window (Wm
in), the maximum width (Wmax), the minimum height (Hmin) and the maximum height (Hmax), and the maximum read width (Wmaxread) of the window is set to Wmin (step 201). Next, one display data such as a chart is read from the real memory 19 which is a message storage device (step 202), and it is determined whether or not the display data such as all the charts is read (step 203).

If the display data of all the charts or the like has not been read, the process proceeds to step 204, where the width of the chart or the like is measured based on the read display data, and the value is read.
Then, it is determined whether or not Wread is larger than the maximum read width (Wmaxread) (step 205).

Here, when the width (Wread) of the chart or the like is larger than the maximum read width (Wmaxread) of the window, the maximum read width (Wmaxread) is set to the width (Wread) of the chart or the like (step 206), and step 202 Then, the display data such as the next chart is read, and the above operation is repeated. If the width (Wread) of the chart or the like is smaller than or equal to Wmaxread, the process directly returns to step 202 to read the display data of the next chart or the like and repeat the above operation.

Then, when reading of display data of all charts and the like is completed in step 203, the control operation proceeds to step 207. Here, the smaller one of the maximum width (Wmax) and the maximum read width (Wmaxread) of the window is set as the minimum value and set as W. Then, the window is deformed and controlled so that the width of the window becomes the set W (step 208), and the window is deformed and controlled so that the height of the window becomes a preset minimum height (Hmin). (Step 209), create a temporary window,
Display a message in the above window (step 21
0). Next, the CPU 14 measures the height of the message displayed in the temporary window, and sets the value as the window height (Hread) (step 211). First, the highest of the minimum height (Hmin) and the height (Hread) of the window is set to the maximum value so that the height of the window is suitable for displaying the message. Further, the lower one of the maximum value and the maximum height (Hmax) of the window is set as the minimum value and set as H (step 212). Then, the window is deformed and controlled so that the height of the window becomes the set H (step 213), and the operation ends.

Thus, the window is displayed on the screen of the display device 18 in a size suitable for displaying the message.

Therefore, according to the present invention, the display area of the window is calculated according to the data amount of the message to be displayed and the display is controlled, so that the message can be displayed in a window within an appropriate range.
