Abstract

PURPOSE:To utilize a window system without making operability adverse even at a compact device. CONSTITUTION:When an already opened window has a super attribute, the window is not closed but any new window is opened (steps S2 and S5). When the window to be newly opened has the super attribute, the already opened window is not closed but the window is displayed (step S3) as well. When the already opened window does not have the super attribute and the window to be newly opened does not have the super attribute, the already opened window is closed and instead of it, the new window is opened (steps S4 and S5).

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display method suitable for use in a portable computer typified by an electronic notebook device.

0002

2. Description of the Related Art Window systems are employed in recent information input/output devices such as computers. In this system, multiple windows can be displayed simultaneously on one screen. Therefore, multiple windows can be compared as needed. This allows the user to proceed with the work more quickly.

0003

[Problem to be Solved by the Invention] By the way, when this window system is used in a small device such as an electronic notebook device, the display screen is small, so even if many windows can be opened at the same time. , you can't actually see many windows at the same time. Therefore, it is necessary for the user to manually close unnecessary windows. As a result, operability deteriorates,
There were some issues that were more inconvenient.

[0004] The present invention has been made in view of this situation, and it is an object of the present invention to enable the use of a window system without deteriorating the operability.

[0005]

[Means for Solving the Problems] The image display method of the present invention is an image display method for displaying a window on a screen, in which the window is divided into a first type of window and a second type of window. The second window can be opened at the same time as other windows, and the second window cannot be opened at the same time as other windows.

[0006]

[Operation] In the image display method configured as described above, the window is divided into a first window that can be opened at the same time as other windows, and a second window that cannot be opened at the same time as other windows. Therefore,
It becomes possible to use the window system without deteriorating the operability.

Embodiment FIG. 2 is a block diagram showing the configuration of an embodiment of an electronic notebook device to which the image display method of the present invention is applied. Reference numeral 1 denotes an input unit including a power switch and other switches, the input of which is supplied to the CPU 4 via an interface 2. The power supply circuit 3 has a built-in battery 3b and an emergency backup capacitor 3a, and supplies necessary power to each part. ROM
5 stores various preset data including programs necessary for the operation of the CPU 4. The RAM 6 stores data necessary for operation as needed. Further, the RAM 7 is a memory backed up by the power supply circuit 3.

[0008] The LCD 9 and the tablet 8 are integrated so that images displayed on the LCD 9 can be viewed through the tablet 8. The tablet 8 constitutes a pressure-sensitive or capacitance type coordinate detection device, and is capable of inputting data input using a pen or the like (not shown) to the CPU 4 via the interface 2. Further, the speaker 10 is configured to output a predetermined audio signal as required.

Next, referring to the flowchart of FIG.
Let's explain its operation. When the CPU 4 receives a window open command from the output of the tablet 8, it executes the processing shown in the flowchart of FIG. That is, in step S1, it is determined whether a window is already open. If no window is open yet, step S5
, and open the window instructed by Tablet 8. That is, the CPU 4 reads out the window from the ROM 5 or the RAM 6 via the interface 2.
Output to D9 and display.

[0010] In step S1, if it is determined that another window is already open, the process proceeds to step S2, where it is determined whether the already open window has the super attribute. If the already opened window has the super attribute, the process advances to step S5 and the designated window is opened. That is, in this case, windows that are already open are not cleared, and 2
Two windows will be displayed at the same time.

[0011] In step S2, if it is determined that the already opened window does not have the super attribute, the process proceeds to step S3, and it is determined whether the newly opened window has the super attribute. . If the newly opened window has the super attribute, the process advances to step S5 and the window is opened. That is, even in this case, an already opened window without a super attribute and a newly opened window with a super attribute are displayed at the same time.

On the other hand, if it is determined in step S3 that the newly opened window does not have the super attribute, the process proceeds to step S4 and the already opened window is closed. Then, proceed to step S5,
The specified window will be opened. That is, in this case, since neither the already opened window nor the newly opened window has the super attribute, only one window will be displayed.

[0013] Therefore, in the case of a window having the super attribute, it is opened together with other windows, and in the case of a window without the super attribute, only one window is displayed.

Furthermore, examples of window display will be explained with reference to FIGS. 3 to 7. In FIG. 3, the LCD
9, a window W1 is displayed on the screen 21. This window W1 is used when copying data to a predetermined page, and does not have a super attribute. In this state, for example, if a command is given to read window W2 (a window that does not have the super attribute) for deleting a predetermined page shown in FIG. Delete W1. Then, as shown in FIG. 5, the designated window W2 is read out, and finally, as shown in FIG.
display on top.

[0015] This allows the user to view window W2 instead of window W1.

On the other hand, as shown in FIG. 7, when the window W4 for the type plate is read out while the window W3 for basic settings is already opened and displayed,
As shown in the figure, the type plate window W4 is opened at the same time as the basic setting window W3. That is, the window W4 of this type plate is set to have the super attribute. The window W4 of the type plate is used to input predetermined characters, and the window W3 is a window in which the characters input from the window W4 are to be recorded. Therefore, in terms of use, it is preferable that both are displayed at the same time. For this reason, window W4 is given the super attribute.

In the embodiment, the characters "Heisei" input from window W4 are written in window W3.

In this way, windows that do not have the super attribute can display only one window at any time, and only windows that have the super attribute can open at the same time as other windows. The capacity of the work memory (RAM 6) used for this purpose can be reduced. Therefore, the window system can be used even in small devices.

[0019]

As described above, according to the image display method of the present invention, a window is divided into a first window and a second window, and the first window can be opened at the same time as other windows. Since the second window cannot be opened at the same time as other windows, the window system can be used without deteriorating the operability.
