Description

The present invention relates to a display device having a window function and capable of specifying a position with two types of cursors, a character cursor and a pointing cursor.

B) Conventional technology Conventionally, a display device, which is a terminal of an information processing device such as a computer, displays a position of a point coordinate on a display screen in addition to a character cursor for displaying a position of a character to be input next. A pointing cursor that does is used. This pointing cursor moves its position on the display screen by operating a pointing device such as a mouse (for the mouse, see Japanese Utility Model Publication No. 60-660).

Many of these display devices have a multi-window function, and a window is formed by designating point coordinates with a pointing cursor. If the pointing cursor does not move after the window is formed, the character cursor will be displayed at the position where the pointing cursor is stopped.Therefore, when entering characters in the window, the normal character input position is determined in advance. Therefore, it is necessary to move the pointing cursor or the character cursor displayed instead of the pointing cursor to the character input position by operating the pointing device or the cursor control key.

C) Problems to be solved by the invention As described above, when inputting characters in the window,
It is necessary to move the cursor to the character input position by operating the pointing device or the cursor control keys.Especially, when the number of windows is multiple, you must move the cursor to the character input position each time you input characters in each window. It was very time-consuming, and the operability was poor.

The present invention has been made in view of this point, and provides a display device capable of easily inputting characters in a window.

D) Means for Solving Problems The present invention is a display device capable of window display and position designation by a pointing cursor corresponding to the operation of a character cursor or a pointing device, and an appropriate number of display devices on the display screen. A window management unit that stores a window area, a character input position management unit that stores position information for character input for each window, a cursor position storage unit that stores a display position of a pointing cursor, and a pointing device And a timer means for counting a predetermined time from the last operation.

(E) Action When the timer means counts a predetermined time, the window management means obtains the window in which the display position of the pointing cursor stored in the cursor position storage means is present, and the character input position management means A character cursor is displayed at the position in the stored window where the character should be input.

F) Embodiment FIG. 1 is a schematic configuration diagram of an embodiment of the present invention. (1)
Is a CPU that controls the information processing apparatus, and (2) is the CPU
It is a main memory in which the control program or data of (1) is stored.

(3) is a keyboard as a key input means, and (4) is a mouse as a pointing device, which is connected via an interface (5) to an input / output control circuit (6) which controls the display device. Reference numeral (7) is a timer connected to the interface (5), which is reset and starts counting each time the last operation of the mouse (4), that is, each time the mouse (4) is operated. Seconds) Outputs a time-up signal when counted.

(8) CRT controller for controlling display of CRT (9) display data, display timing, etc., (10) font memory for storing character patterns, (11) generating character cursor and pointing cursor pattern A cursor pattern generating circuit (12) is a save memory for temporarily storing the original display data of the portion where the cursor is displayed when the cursor pattern is displayed.

(13) is a window management memory that stores a plurality of window areas on the CRT (9) screen, (14) is a character input position management memory that stores position information for inputting characters for each window displayed, (15) is a pointing cursor CRT that moves in response to the operation of the mouse (4)
(9) A pointing cursor position register for storing the indicated position on the above.

Now, assume that two windows are provided and displayed on the CRT (9) screen. That is, the window management memory (13) stores two window areas, and the character input position management memory (14) stores position information for the next character input in each of the two windows. A pointing cursor is displayed on the CRT (9) screen, and its display position is stored in the pointing cursor position register (15). The display of the pointing cursor is CRT
The controller (8) is the cursor pattern generation circuit (11)
Extract the pointing cursor pattern from the CRT
It is displayed at (9) (see FIG. 2A). When the pointing cursor is displayed, the display data before the portion where the pointing cursor is displayed is stored in the save memory (12). When the mouse (4) is operated, the X
The amount of movement in the −Y direction is sent to the input / output control circuit (6) via the interface (5), and the CRT controller (8)
The pointing cursor is moved and displayed in accordance with the moving amount, and the position information of the cursor in the pointing cursor position register (15) is rewritten. The contents of the save memory (12) are also rewritten by the CRT controller (8) by moving the pointing cursor.

When the mouse (4) is operated, the timer (7) starts counting from the time when it is operated. When the mouse (4) is operated again before counting for a predetermined time, the timer (4) is reset and counting is started from the beginning. When the timer (4) counts a predetermined time (for example, 2 seconds), the timer (4) transmits a time-up signal to the input / output control circuit (6) via the interface (5).

Then, the input / output control circuit (6) compares the contents of the pointing cursor position register (15) with the contents of the window management memory (13) to check in which window area the pointing cursor is displayed. When the pointing cursor is not in any window area, the pointing cursor is displayed as it is. When the pointing cursor is in either window area, the character input position management memory (14) further reads the position information for the character input of the window in which the pointing cursor is displayed,
The CRT controller (8) erases the display of the pointing cursor, reads the original data from the save memory (12) and displays it, and at the same time, the cursor pattern is generated in the position where the pointing cursor was displayed in the character input window. A character cursor pattern is generated and displayed from the circuit (11) (see FIG. 2B). At this time, if there is a display in advance at this position, the display data is stored in the save memory (12). Then, when inputting characters, if key input is performed from the keyboard (3) in this state,
The character pattern corresponding to the input key is read from the photon memory (10) and input at the position where the character cursor is displayed. When a character is input, the character input position of the corresponding window in the character input position management memory (14) is 1
Move forward.

When the mouse (4) is operated while the character cursor is displayed, the character cursor is erased and the pointing is performed in correspondence with the movement amount operated from the position stored in the pointing cursor position register (15). The cursor is displayed and moves.

Further, when there is a key input from the keyboard (3) while the pointing cursor is being displayed or the mouse (4) is being operated and the pointing cursor is being moved, the window in which the pointing cursor is displayed is determined in the same manner as described above, and the A signal of the key input to the window is sent, and the processing is performed for each window, such as input to the pointing cursor pointing position or the position indicated by the character input position management memory (14).

It is obvious that the present invention can be applied even if the number of windows is one or more.

As is apparent from the above description, the present invention is such that, when a character is input in a specific window, the pointing cursor or the pointing device or cursor control key is moved to a position where the character should be input. Even if it is not operated, the character cursor is displayed after a predetermined time has passed to the character input position in the window where the pointing cursor is located. Therefore, when inputting characters in a window, especially when multiple windows are set and characters are input across each window, the character cursor is automatically displayed at the character input position, improving operability. Can be achieved.
