Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard input suppression computer for suppressing input of keys not used by a keyboard in a plant monitoring system employing a multi-window.

In a plant monitoring system employing a multi-window, a plurality of window screens can be simultaneously displayed on a monitor.
In this case, by selecting (active) a window screen to be operated by a mouse or keyboard operation, a key event or a mouse click event from an input means such as a keyboard or a mouse is delivered to the selected window screen, and the event is transmitted to the selected window screen. The function assigned to is executed.

For example, in a plant monitoring system employing a multi-window, there is a plant monitoring system in which buttons for executing functions A and B are arranged on an activated window screen.
In addition, keys are assigned so that these functions can be executed by keyboard operation, and a key “A” is assigned to the function A and a key “B” is assigned to the function B.
In such a print monitoring system, when the user wants to execute the function A, he or she clicks the area of the button A by operating the mouse or presses the key 'A' assigned as the key for executing the function A.
The mouse click event generated by the mouse click is transmitted to the window screen displayed at the clicked coordinates, and is delivered to the active window screen when the key “A” on the keyboard is pressed.
The window screen to which the event is delivered is determined from the coordinate position where the mouse is clicked or the transmitted key code, and executes the function A.

JP-A-5-109336 (page 2, FIG. 2)

In the above-described example, when the function A cannot be executed, the print monitoring system informs the user that the operation cannot be visually performed, for example, by turning off the button.
In this state, when the mouse is clicked on the coordinates of button A, the mouse click coordinates are distributed to the window screen displayed at the coordinates.
The window screen that has received the distributed mouse click coordinates does not perform any processing because the function A cannot be performed.
In addition, since the user is invisible, the user can intuitively understand that the operation cannot be performed.

On the other hand, when the function A is to be implemented by operating the keyboard, when the key 'A' on the keyboard is pressed, the key 'A' is delivered to the active window screen. Since the function A cannot be performed on the window screen, the function A is not performed.
However, since the user can physically press the keyboard, it is not known whether the function assigned to the key 'A' has been executed.
Therefore, it is common to display an error message to the user to indicate that the function A could not be executed.
As described above, when there are both the input means of the mouse operation and the keyboard operation, it is possible to visually indicate that the mouse operation is not possible, whereas in the case of the keyboard operation, the keyboard is physically pressed. It will be displayed in an error message later.
For this reason, when performing an input operation from a keyboard operation, it is necessary to temporarily suspend the operation and determine the content of the error message, and there has been a problem that the operation efficiency is reduced.

As a method of suppressing input of a key on an unused keyboard, for example, in Patent Literature 1, keys other than keys (functional keys) displayed on a menu (screen) do not function by being locked by a key switch lock function. Only keys that work are delivered to the menu because the keys cannot be physically pressed.
When this patent document 1 is applied to a multi-window compatible program, keys outside the active window do not function even if displayed on a monitor. Patent Literature 1 does not refer to correspondence to keys outside these active windows.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and has as its object to provide a keyboard input suppression calculator that suppresses input of keys not used by a keyboard even in a multi-window display.
