Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a screen display control method, and in particular to a screen display control method, in which a non-transparent window and a transparent window are provided on the screen, and multiple types with different properties are provided, such as displaying characters etc. in the background. The present invention relates to a screen display control method that enables two-way display/editing by integrating information on the screen.

(Technical Background and Problems) Conventionally, in order to integrate and display multiple types of information on one screen, multi-windows have been provided to display predetermined information.

For this reason, 2. For example, when trying to display characters etc. overlapping the background, 2. extract only the part corresponding to the characters, etc. to be displayed, and write the extracted characters etc. overlappingly on the background. The process was complicated and inconvenient.

It is also conceivable to provide a transparent window in addition to the non-transparent multi-window described above, write the background on the non-transparent window, and provide a transparent window with characters etc. written on top of the non-transparent window. There has been no screen display control method for effectively controlling a system in which non-transparent windows and transparent windows coexist.

(Object and Structure of the Invention) An object of the present invention is to solve the above-mentioned problems, and to provide a non-transparent window and a transparent window on one screen, and to write new characters etc. in the position where the transparent window exists. When doing so, first remove all transparent windows that exist above the text, etc. of the current window, including the window to be written, and after writing the text, etc. in the window, perform the process of overlapping the windows again. By doing so, the objective is to realize a transparent window through simple processing, and to easily integrate, display and edit multiple types of information with different properties. Therefore, the screen display control method of the present invention divides one display screen into a plurality of independent transparent windows and non-transparent windows that are allowed to overlap, and displays the visible area displayed by the plurality of windows. a window definition body for defining the window, a screen division map calculation unit that calculates an area to be displayed on the screen based on information from the window definition body, and a map table on the screen division map calculation side; and a display control unit that displays a predetermined image on the screen based on the information stored in the screen pollution IJA table, and when the window to be drawn is itself a transparent window or the window to be drawn. a drawing pre-processing means for temporarily removing all the overlying transparent windows, including the transparent window, from the window definition body when a transparent window covers the top; A drawing means that performs a predetermined drawing after temporarily removing a predetermined transparent window from the window definition body, and a drawing reconfiguration that displays a screen while sequentially separating the removed transparent window again after drawing by the drawing means. It is characterized by comprising a processing means.

(Example of the invention) The present invention will be described in detail below with reference to the drawings.

Window buffers 2-1 to 2-ri in the figure are for storing the contents written in the windows, respectively.

In the figure, the display control unit 3 refers to the screen division map table 6 to transfer the information stored in the window buffers 1 to n to the screen buffer 7 in order to display a predetermined screen according to instructions from the operation console 1. It is for storing.

A window definition body 4 in the figure defines each window arranged on the screen. The contents of this definition will be described later using FIG.

In the figure, the screen bone 1pj map calculation unit 5 is the window definition body 4
Contents stored in 1. For example, information such as the degree of overlap between windows and the vertical relationship. A screen division map that determines how the characters written in each window should be displayed on the divided screen based on this information. It is for calculating qF@. The calculation result is stored in the screen division map table 6.

A screen buffer 7 in the figure is used to store contents to be displayed on the screen 8 in units of pixels.

FIG. 2 shows an example of the structure of a window definition body stored in the window definition body 4, in which all information regarding the position and vertical relationship between windows is stored.

Wo to Wn at the left end of the figure indicate windows, and fi
Indicates that +1 windows are defined.

In the figure, Po through Pn are used to create a table that stores window definitions, and store pointers having relationships shown by arrows.

In the figure, FO to Fn describe the order, etc. indicating the vertical relationship of the windows.

In the figure, Xla and Yla indicate the coordinates (Xla, Yla) of the upper left corner defining the rectangular window WO.
b and Ylb indicate the lower right coordinates (Xlb, Ylb). Thus, by indicating the size and position of each window with coordinates.

Easily calculate the relationship between each window with screen division map calculator 5
It can be calculated by Information such as whether the window is transparent or non-transparent is also stored.

The following describes the process for changing the character "C" in the 9th screen to the character "B" to change the character to the character (105) when the character 1 (101) in FIG. 3 is displayed on the screen 8. . At this time, the vertical relationship of the windows is as follows from the bottom to the top: WO→W1→W2→W3. Windows WO and W3 are non-transparent windows, and WO has a diagonal line rising to the right as a background, and W
There is nothing written in 3. On the other hand, Wl and W2
is a transparent window, the letters "AC" are written in Wl, and a diagonal line downward to the right is written in W2.

In the figure, (102) indicates processing that must be performed in advance to change the character "C" drawn in the transparent window W1 to the character "B". In other words, the transparent window W1 in which the character "aC" is written and the transparent window W2 existing above the area of the character "C" are removed from the window definition body and the two-screen division map is recalculated.Then, the two-screen division map is recalculated. This shows a state in which the area on the window WO corresponding to the area (ΔA) where `` was drawn has been cleared.

In the figure, (103) shows a state in which a diagonal line rising upward to the right, which is the same as that drawn in the non-transparent window WO, is drawn in the area (ΔA) on the cleared non-transparent window.

In the figure, (104) is after adding the transparent window W1 to the window definition body and calculating the screen division map.

A state in which the character "B" is drawn by performing a logical OR operation between the area corresponding to the ΔA and the character "B" to be written is shown.

In the figure, (105) is after the transparent window W2 is added to the window definition body and the screen division map is calculated.

This shows a state in which a diagonal line downward to the right is drawn by performing a logical OR operation with the diagonal line downward to the right, which is the content of the transparent window W2.

The character “C” (illustrated (101)) drawn on the transparent window W1 as explained above is changed to the character “B” (
(105) shown in the figure.
