2. Description of the Related Art In the office, the creation of multimedia documents using computers has become popular. In some cases, multiple applications are processed simultaneously to create a single document.

In such a system, a plurality of windows may be displayed in an overlapping manner, or the data of one application may be used by another application.

Normally, when inputting data in an application, a data input request window is displayed and input is made. When a data input request window is displayed by a certain application, it is not possible to input to other windows in the application, but it is often possible to input to the windows of other applications.

In the conventional input control device in the multi-window system, the shape of the mouse pointer is the same in the input enabled window and the input disabled window, and it is impossible to determine whether the input is enabled or disabled on the screen.

[0006]

The input control device in the above-mentioned conventional multi-window system is such that when a plurality of windows are displayed, the mouse pointer of the same shape is displayed in any window regardless of whether the input is possible or not. Since it is displayed, there is a problem that an erroneous operation such as an attempt to perform an input operation on a non-input window is easy.

There is also a problem that it is impossible to determine whether the input is possible or not unless the mouse is actually input.

An object of the present invention is to provide an input control device in a multi-window system in which erroneous operations can be markedly reduced by changing the display of the mouse pointer between the input enabled window and the input disabled window.

[0009]

An input control device in a multi-window system according to the present invention comprises an input means for inputting a command and data, a command received by the input means, decoding the command and corresponding processing. Command instructing means for instructing, the command processing means for performing the processing instructed by the command instructing means, and the data input by the instruction of the command processing means when the input command requests the display of the data input request window. When the mouse pointer is in the data input enabled window, a first display signal is generated, and when the mouse pointer is in the data input disabled window, a second display signal is generated. Generated and input from the input means Input control means for prohibiting, and when the input command requests the display of the data input request window, the data input request window is displayed according to the instruction of the command processing means and responds to the supply of the first display signal. Display means for displaying the display of the mouse pointer in the first shape and displaying the display of the mouse pointer in the second shape in response to the supply of the second display signal.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an input control device in the multi-window system of the present invention.

The input control device in the multi-window system of this embodiment, as shown in FIG. 1, executes an input means 1 for inputting a command or data, a decoding decision of the command input by the input means 1 and a corresponding process. Command instructing means 2 for instructing, command processing means 3 for reading out data from the data storage file 6 in accordance with an instruction from the command instructing means 2 and giving an instruction to the display means 5 and the input control means 4, a mouse for displaying a data input request window The position of the pointer is judged and the display means is instructed to change the display shape of the mouse pointer depending on whether it is in the input enabled window or the input disabled window. From the input control means 4 which sometimes instructs the input means 1 to prohibit the input, and the command processing means 3. And a display means 5 for displaying by changing the display shape of the mouse pointer according to an instruction from the display data input request window also input control means 4 by an instruction.

FIG. 2 shows an example of a screen on which a plurality of windows are displayed when this embodiment is operated.
Before the data input request window is displayed on the screen 21, the display shape of the mouse pointer is the same in each inputtable window. When the data input request window is displayed on the screen 22, a mouse pointer of an arrow mark indicating that input is possible is displayed in a window where input is possible, and a mouse pointer of a prohibition mark indicating that input is impossible is displayed in a window where input is not possible.

FIG. 3 is a flow chart showing the operation of the input control device in the multi-window system of this embodiment. The operation of this embodiment will be described with reference to FIGS.

First, a command is input from the input means 1 (step 31).

The input command is decoded by the command designating means 2 to determine whether it is a "data input request window display" command (step 32).

When it is determined that the input command is not the "data input request window display" command (NO branch of step 32), the process corresponding to the command is executed (step 41) and the process ends.

When it is determined that the input command is the "data input request window display" command (YES branch of step 32), the command processing means 3 reads the necessary data from the data storage file 6, and An instruction is given to the display means 5 to display the data input request window. Further, the command processing means 3 gives an instruction to the input control means 4, and by this instruction, the input control means 4
Divides the input-enabled window and the input-disabled window (step 33).

Then, the input control means 4 judges whether the window in which the mouse pointer is currently positioned is ready for input or not (step 34). If the window is not ready for input (NO branch of step 34), the mouse pointer The display means 5 is instructed to set the display shape of the mark as a prohibition mark which cannot be input.
This is displayed and the input means 1 is instructed to prohibit input (step 35), and the mouse pointer is moved to the input enabled window (step 3).
6, 34 and 35).

When the above-mentioned judgment of the input control means 4 is possible (YES branch of step 34), the display means 5 is instructed to make the display shape of the mouse pointer into an enterable arrow mark, and the display means 5 displays this. Is displayed (step 37) and the mouse pointer is moved to a predetermined data input position (steps 38, 36, 34 and 37).

If the mouse pointer is positioned at a predetermined data input position (YES branch of step 38), data input is started (step 39) and input of all data is finished (YES branch of step 40).

[0022]

As described above, the input control device in the multi-window system of the present invention, when the data input request window is displayed, moves the mouse pointer between the input enable window and the input disable window. By changing the shape, it is possible to explicitly determine whether the input is possible or impossible, and it is possible to significantly reduce the erroneous input operation.
