Abstract

PURPOSE:To easily process a key input monitor task by comparing a cursor position, and a window position designation of all window defining information which has been registered, and displaying a task discrimination corresponding to the window. CONSTITUTION:A central processor 1 is connected to a window defining information managing means 3 through a bus 2, and the means 3 executes a registration and an elimination of window defining information with respect to a pair information store means 4. Also, a pair information register means 5 fetches and stores all the window defining information by one information each, which has been registered in the means 4, and in the window defining information in the means 5, a window position designation is compared with a cursor position which is sent from a cursor position signal 7, in a cursor/window comparing means 6. As a result, if the cursor is contained in the window corresponding to the window defining information in the means 5, a task identifier display means 8 displays a task identifier in the means 5, to the bus 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a graphics control device that performs graphics state change processing based on data input in a computer graphics system, particularly an interactive multi-window system.

[Conventional technology]

Conventional graphics control devices, when displaying the current cursor position on the screen, do not store a correspondence table between window positions and tasks, and instead display the identifier of the window containing the current cursor position. , there is no way to check and display the task identifier corresponding to that window.

[Problem that the invention seeks to solve]

When trying to realize a multi-window system using the conventional graphics control device described above, the task of monitoring input from the operator is to obtain the cursor position from the graphics control device every time there is an input,
Refer to the table of window definition information in memory,
The process of determining the task that should receive the input data and sending the input data to that task must be performed.

Since this processing is performed every time data is input by the operator in a multi-window system, it has a large effect on the performance of the entire system and the response speed to input from the operator.

Conventional graphics control devices have not been devised to speed up this processing, so the performance of multi-window/stem cannot be improved.

[Means for solving problems]

A graphics control device according to the present invention includes: a window definition information storage means for storing pair information of a task identifier and window position specification as window definition information; a window definition information management means for adding and deleting the pair information; pair information processing/task means for sequentially extracting and storing all pair information registered in the window definition information storage means in response to a graphics state change request caused by an input operation from a data input device by an operator; A cursor that compares the window position specification, which is part of the window definition information stored in the pair information register means, with the cursor position information to determine whether the cursor is included in the window corresponding to the pair information. It has a window comparison means, and a task identifier display means for extracting and displaying a task identifier from the corresponding information register means when the cursor is included in the window according to the output determination information from the cursor/window comparison means. ing.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 represents one embodiment of the invention.

For the sake of simplicity, the entire graphics control device is not described in FIG. 1, but only the means that characterize the invention are described.

The central processing unit @1 is connected via system path 2 to the graphics control unit. The window definition information management means 3 of the graphics control device registers and deletes window definition information in the associated information storage means 4.

The counter information register means 5 is a means for extracting and storing all the window definition information registered in the counter information storage means 4 one by one. - The window comparison means 6 compares the cursor position with the cursor position sent from the cursor position signal 7. As a result, when the cursor is included in the window corresponding to the window definition information in the counter information register means 5, the task identifier display means 8 displays the task identifier of the counter information register means 5 to the system bus 2. do.

Self-made 2 yen Zl soil - Ument 9 Tsugo de 2 & Jujuji qσ) -
It is expressed as a state stored in the pair information register means 5. The window definition information consists of a task identifier 9 and a window position specification IO.

The present invention will be described in detail below based on an example of operation of a multi-window system.

In a multi-window system, the operator first
Assume that a screen-operable file editing program (hereinafter referred to as a screen editor) is started by specifying that a certain window on the screen, for example, window 1, be used. Then, the screen editor uses the window definition information management means 3 for the graphics control device to register window definition information consisting of its own task identifier and the window position designation of window 1 in the counter information storage means 4. . Window 1 displays characters and the like for file editing.

Then, to view the contents of another file, the operator:
Assume that you start a file print program by specifying that a certain window on the screen, for example window 2, be used. The file print program uses the window definition management means 3 to register window definition information consisting of its own task identifier and the window position designation of the window 2 in the information storage means 4. Window 2 displays part of the contents of the file. At the bottom left of window 2, the part that follows the fully displayed part of the file (next -)) and the part immediately before it (
A menu (
Assume that a menu (hereinafter referred to as the Zeno scroll menu) is displayed. The state of the screen at this time is shown in FIG.

In this situation, assume that the operator moves the cursor to the second scroll menu 13 and presses a certain key in order to instruct the display of the next item on the file/print/program.

At this time, the window position designation in the two window definition information registered in the pair information storage means 4 and the current cursor are compared by the cursor window comparison means 6, and as a result, the task identifier display means 8 displays the file. By displaying the print glogram task identifier, the key human monitoring task can easily know that the key that the operator has just entered is for the file print program. You can quickly receive instructions to scroll.

Suppose that the operator then terminates the file printing program. At this time, the file print program requests the graphics control device to delete the file definition information together with its task identifier by requesting the window definition information management means 3 to delete the contents of the information storage means 4. , can be managed as the window changes. When comparing the cursor position and the specified window position, by setting the order in which the window definition information is output from the pair information storage means 1 in the order in which they were newly registered, it is possible to compare windows that overlapped with each other. It is also possible to correctly extract and display the task identifier.

〔Effect of the invention〕

As explained above, the present invention stores window definition information, compares the cursor position with the window position specifications of all registered window definition information, and determines the task identifier corresponding to the window containing the cursor. The display facilitates the processing of key human monitoring tasks in multi-window systems, thereby reducing the CPU load and increasing overall system performance, while also increasing the responsiveness of multi-window systems. It brings about the effect that it can be realized.
