JP2541612B2 - Multi-window display - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a plurality of areas (hereinafter, referred to as “display areas”) displayed on a screen.
It is called a "window". ), Each of which displays an independent image.

(Prior art) Multiple display areas are provided on the screen of CRT at the same time to display the contents of multiple documents, different parts of the same document can be displayed at the same time, and the contents and layout of documents can be displayed at the same time. There is a multi-window type image display device that can be displayed.

This multi-window type image display device displays, for example, a plurality of windows W superimposed on the screen such as the CRT shown in FIG. 2 and simultaneously displays images such as independent character groups or figures in these windows W respectively. It is configured to be displayable, and it is possible to easily compare independent images for each window W.

You can also change the size of the window and scroll the display information in the window.

(Problems to be Solved by the Invention) However, in such a multi-window display device, a window frame area is controlled in order to control the display position of a document or the like in a window and control for changing the size of the window. It was provided and the icons were used to give instructions. Therefore, the display area of the display information of each window is reduced by the window frame area.

The present invention has been made in view of such a conventional situation, and displays the window control icon required for the multi-window display device while opening the window frame area for display information as much as possible. However, the purpose is to enlarge the display area of the currently displayed document or the like to facilitate the operation / judgment for the document or the like, which is the original work of the operator.

(Means for Solving the Problems) The multi-window display device of the present invention is required for a plurality of display information displayed in each of a plurality of windows set on one screen and for controlling the plurality of windows. Main memory means for storing a window frame pattern provided with various icons, a frame memory for storing the window frame pattern in the display information and storing it as one window, and a display means for displaying the information in the frame memory. In the multi-window display device,
For the icon writing device that performs writing along with the display and movement of the icon on the frame memory, and the area other than the icon after writing, or the area that is not displayed due to the movement of the icon, the background information that writes the display information. Built-in device.

(Operation) In the window frame area, a so-called scroll bar for indicating the position of the current display area of the window and for moving the current display area up, down, left and right in the currently displayed document,
Also, an icon necessary for controlling the window itself such as enlargement / reduction / movement of a so-called size box for changing the size of the current display area is provided.

Conventionally, as shown in FIG. 2, the window frame area occupies a considerable area in the entire window, and a portion for displaying display information such as a document is small. The icon itself is indispensable for window control, but it is not necessary to occupy the area around the icon or the movable area as a window frame area, and the display information displayed in the window can be extended to that area. It may be displayed as a background.

Window frame pattern of the present invention Fig. 3 (a), (b)
Displays only icons such as a scroll bar and a size box, and the area other than the icons in the window frame area extends the display information in the window and displays it as the background. Specifically, in the present invention, the icon writing device performs display accompanying the movement of the icon, and the background writing device displays the display information in the blank area after the icon movement.

(Example) A multi-window display device of the present invention will be described below based on an example shown in the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

Is a main storage means for storing a plurality of documents (TEXT 1 to n) displayed in a multi-window and a window frame pattern according to the present invention. Is a central processing unit (CPU), which edits the display information read from the main storage means for performing multi-window display, controls each window including the window frame pattern according to the present invention, and processes the control information. Has the function of performing. Is a frame memory (VRAM) in which a window frame pattern according to the present invention is fitted to a part or all of display information of a document or the like and stored in a multi-window form corresponding to the processing situation of each document or the like. Outputs memory information to CRT. Is the CPU bus and this CP
Input devices such as main memory, frame memory, keyboard unit and mouse are connected to the U bus.

In multi-window display, the CPU cuts out the entire display information such as a document in the main storage unit or one page, etc., which is necessary for the current display, and the window extracted from the main storage unit on the frame memory. Fit the frame pattern and display it on the CRT.

Next, the display of the window frame pattern performed by the CPU will be described. Is an icon writing device, and is a background writing device.

The icon writing device deletes the corresponding icon in the frame buffer to change the display position of the icon when the input device is instructed to control the window, that is, to change the window size or scroll the data in the window. Perform the action of writing the icon in the position. When a new window is newly created, the above icon deleting operation is skipped and the same operation is performed.

On the other hand, the background writing device receives a background omission caused by the above icon writing operation from the icon writing device, calls display information corresponding thereto from the main storage means, and performs the writing operation as the background. When a new window is newly created, the background information is similarly written in the window frame area other than the icon display area.

In the above embodiment, the main storage means is accessed for each rewriting, but the information displayed in one window is copied from the main storage means to the window memory in advance, and the window memory is accessed at the time of rewriting. You can also

(Effects of the Invention) As described above, the multi-window display processing device of the present invention reduces the display area of the window frame pattern on the screen and increases the content information display of a document or the like, so that the operator's original It is possible to facilitate operations and judgments on documents, which are business tasks, and significantly improve the work efficiency of office work.
