Abstract

PURPOSE:To reduce the quantity of processing for redisplay operation and to speed up the processing by interrupting retrieval for other redisplay areas and moving to next investigation when a display is made in a specific redisplay area among redisplay areas which are rearranged and integrated. CONSTITUTION:A redisplay control part 3 after rearranging and integrating redisplay object areas indicated from a screen control part 1 checks whether or not all vector data defined in a currently aimed window among plural redisplay object windows indicated from the screen control part 1 are included in the individual redisplay areas. When vector data is included in a checked redisplay area, the vector data is displayed and the subsequent investigation of the necessity of a display in other display object areas is interrupted and whether next vector data is included in a display object area or not begins to be investigated. Consequently, the need to investigate whether or not redisplay processing is performed in other display areas is eliminated and the redisplay processing is speeded up.

Description

[Detailed Description of the Invention] [Summary] Regarding a method for displaying image data in a multi-window, when a certain window is deleted, part of graphic data in a plurality of windows below it is redisplayed. In order to reduce the amount of redisplay processing and perform redisplay at high speed, we provide a means to organize and integrate multiple redisplay areas designated for each window, and all shapes unique to each window. A means for searching data to determine whether or not it exists within the redisplay area that has been organized and integrated is provided. While searching for something, when it is displayed in a specific redisplay area among the redisplay areas that have been organized and integrated,
The configuration is such that the search for the other re-display areas is interrupted and the process moves on to search for the next graphic data as to whether or not it exists within the re-display area.

[Industrial application field]

The present invention relates to a system for displaying graphic data in multiple windows, in which when a certain window is deleted, part of the graphic data in a plurality of windows below it is redisplayed.

With the recent diversification of data processing and improvements in the processing power of data processing devices, the number of windows that display data in multi-windows has increased, and the number of graphical data, such as vector data, displayed in each window has also increased. There is a trend to do so.

Therefore, if a certain window is deleted during data processing, the process of redisplaying some of the graphical data of the multiple windows below it can be performed as quickly as possible. A refresh method is required.

[Prior art and problems to be solved by the invention] FIG. 3 is a diagram illustrating a conventional window redisplay method.
(a) shows the concept of window redisplay, (b) schematically shows a configuration example of the redisplay mechanism, (c) shows the processing flow when redisplaying, and (d) shows the concept of redisplay processing. It shows.

Typically, multiple windows, e.g. windows A, B,
In a system that displays data in C, when a certain window B is removed, for window A and window C that are below window B, (a) as shown in the figure, The area that needs to be redisplayed is a combination of multiple rectangles.

For example, as shown in Figure (b), the redisplay mechanism performs operations on individual windows, such as opening and deleting windows, based on requests from each application.
In order to process movement and manage which area needs to be redisplayed for the target window, for example, have window area data for each application,
When a certain application instructs the deletion of a specific window, the area of multiple windows below the deleted window is divided into rectangular areas, and a redisplay instruction is issued to the redisplay management unit 3a, which will be described later. Screen management units 1 and 1 manage graphic data (for example, vector data) defined in each window for each window Data management units 2 and 5 To redisplay necessary graphic data for each window The redisplay management section 3a executes the processing (see figure (C)).

Conventionally, the redisplay management section 3a has executed the process shown in FIG.

The feature of this conventional method is that, as the concept is shown in FIG. , all the graphic data in the window (
vector data) is within the redisplay area (processing steps 36 and 37), and if it is within the redisplay area, display the vector data (processing step 33). This is repeated for all vector data in the window for the redisplay area.

The reason for this type of processing is that it was originally a process for opening a window and displaying various graphical data in the window. 37. Focusing on the existence of the routine 33, use that routine to check whether there is data to be displayed in each redisplay area, and if there is, configure it to display it. This is because the process for redisplaying can be easily configured.

In this conventional method, as shown in FIG.
All graphic data (vector data) in the window
is within the redisplay area (processing steps 36 and 37), and if it is within the redisplay area, display the vector data (processing step 33). However, since it is repeated for all the vector data in the window, if the number of windows is small and the number of vector data in each window is not large, as in the case of It took advantage of its simplicity and was sufficiently practical.

However, recently, the number of windows has increased,
In addition, as the number of graphic data (vector data) displayed in each window increases, the comparison process (processing steps 36 and 37) to determine whether or not there is vector data in each redisplay area is performed as follows. There was a problem in that the number of regions increased by the number of vector data.

Furthermore, if certain vector data spans multiple re-display areas, the above comparison process for the vector data is executed multiple times, and the display of the vector data is also performed multiple times. There was a problem.

In view of the above-mentioned conventional drawbacks, the present invention provides a system for displaying graphic data in a multi-window, in which when a certain window is deleted, some of the graphic data in the plurality of windows below it are re-displayed. It is an object of the present invention to provide a window redisplay method that can perform redisplay at high speed by reducing the amount of processing required for redisplay.

[Means to solve the problem]

FIG. 1 is a diagram explaining the principle of the present invention, in which (a) shows the concept of processing, and (b) shows the processing flow.

The above problem is solved by a window redisplay method configured as follows.

A certain window was deleted when displaying graphic data in multiple windows. In this case, a method for redisplaying part of the graphical data in multiple windows under the above-mentioned window is provided. Means 30, 31, and 32 are provided to search for all graphical data unique to the above-mentioned organized and integrated redisplay area to determine whether or not it exists within the redisplay area that has been organized and integrated. While searching for whether or not it exists in the redisplay area, if it is displayed in a specific redisplay area among the redisplay areas that have been organized and integrated, the search for other redisplay areas may be performed. 32, 33, and 30, the process is interrupted and the process moves to a search process for determining whether or not the next graphic data exists within the above-mentioned re-display area.

[Effect]

That is, in the window redisplay method according to the present invention,
While the conventional window redisplay method performs a comparison process for all vector data in each redisplay area of each window to see whether the vector data exists in the redisplay area, first, Focusing on one of the windows that needs to be redisplayed, a list of rectangular areas that have needed to be redisplayed up to the present time is created for that window, and then each area is organized and integrated.

Specifically, when a certain area α includes a specified area β due to the deletion of another window, means ■a for including the area β in the area α, and a certain area γ, When there is an area δ specified due to the deletion of another window, an area ε including the area γ and the area δ is set, and most of the set area ε is transferred to the area γ , and, when it is determined that the area δ occupies, means (ii) b for integrating the areas γ and δ as the area ε are provided.

By organizing and integrating the redisplay areas, it is possible to reduce the amount of processing required to determine whether certain vector data exists in the redisplay area.

Next, it is checked whether or not there is vector data to be displayed in the certain window of interest, and if there is vector data to be displayed, the following processing is performed.

That is, for each hector data defined in the window, it is checked whether it is included in the redisplay area in the window, and if it is included in the redisplay area, the vector data is displayed. .

Since the displayed vector data has already been displayed, it is unnecessary to investigate whether it is included in the remaining unexamined redisplay area, and the investigation process is interrupted and the same process is performed on the next vector data. Move the investigation process. (See FIG. 1(a)) In other words, the redisplay method according to the present invention determines for each window whether or not all vector data within the window needs to be displayed in the individual redisplay area. Check whether the vector data is included in the redisplay area, and if it is recognized as included in one redisplay area, the vector data will not be displayed again even if it spans multiple redisplay areas. By not performing the above-mentioned investigation on the area, the redundant processing required in the conventional method can be avoided, which has the effect of speeding up the redisplay processing.

〔Example〕 Embodiments of the present invention will be described in detail below with reference to the drawings.

The above-mentioned FIG. 1 is a diagram explaining the principle of the present invention, and FIG. 2 is a diagram showing an embodiment of the present invention, in which (a) shows an example of the system configuration, (bl), (b2 ) shows an example of organizing and integrating redisplay areas.

In the present invention, when there is an instruction from the screen management unit 1 to redisplay a plurality of windows, first, attention is paid to a specific window, and the redisplay area required up to the present time is means (2) for extracting, organizing and integrating the above, and means (3) for determining whether or not all graphic data (vector data) defined in the window are included in the re-display area that has been organized and integrated.
0.31.32, if a redisplay area containing the corresponding vector data is found, an instruction to display the vector data is issued, and from now on, whether or not the hector data is included in another display area is determined. Means 32, 33, and 30 for interrupting the investigation of vector data, extracting the next vector data, and proceeding to the same investigation process are necessary means for carrying out the present invention. Note that the same reference numerals indicate the same objects throughout the figures.

Hereinafter, the window redisplay method of the present invention will be explained with reference to FIG. 2 while referring to FIG.

First, in the screen management department, from each application, 1
When receiving an instruction to delete one or more specific windows, it refers to the window area corresponding to the application that it manages, and deletes the multiple windows located below the window that was instructed to be deleted. recognize the redisplay area for each redisplay area, divide the redisplay area into a plurality of rectangular areas,
The redisplay management unit 3 of the present invention is notified of the divided redisplay area.

The redisplay area organization/integration unit in the redisplay management unit 3 focuses on one of the windows that received the notification, and creates a list of areas that have required redisplay up to this point for that window. After creating , the redisplay areas shown in Figures 2 (bl) and (b2) are organized and integrated.

■a: Redisplay area organizing process As shown in Figure 2 (bl), an N area β is specified in a certain area α due to the deletion of another window.
is included, by including the region β in the region α, step 30 shown in FIG. 1(b) is performed for the region β.
33 can be made unnecessary.

■ b = Redisplay area integration process When there is a certain area γ and an area δ specified due to the deletion of another window, the area γ and the area δ
Most of the set area ε,
For example, when it is determined that the area γ and the area δ occupy 80% or more, by integrating the areas γ and δ as the area ε, the area ε is replaced with the area T and δ. Therefore, it is sufficient to execute the processes of steps 30 to 33 shown in FIG. 1(b), and the amount of processing for redisplaying can be reduced.

Next, the redisplay management unit 3 sends the data management unit 2 the following information:
Inquire about the vector data to be displayed, and perform the above sorting and processing for each window based on the vector data of that window.
The processes of steps 30 to 33 shown in FIG. 1(b) are executed on the integrated redisplay area.

Step 30: Search whether vector data exists for the window of interest.

Step 31: If vector data exists in the window of interest, check whether there is an area to be redisplayed.

If not, the process returns to step 30 and proceeds to process the next vector data, but if there is a region to be redisplayed, the process proceeds to the next step 32.

Step 32: Check whether the vector data of interest is included in the area to be redisplayed.

Then, when it exists in the redisplay area, the next step 3
3, but if it does not exist, return to step 31 and perform the same investigation for the next redisplay area.

Step 33: Display the hector data, interrupt the investigation to see if it exists in the unexamined re-display area, and return to step 30 to display the next vector data. , perform the same investigation process.

Therefore, in the present invention, one vector data is
Even if vector data spans multiple redisplay areas, the vector data is displayed as soon as it is found to exist in the first referenced redisplay area. No display processing is performed.

As described above, the present invention organizes and integrates the areas to be redisplayed as instructed by the screen management unit, and then selects the area that is currently being focused on among the multiple windows to be redisplayed that have been notified from the screen management unit. All vector data defined in the current window is checked to see if it is included in each redisplay area, and if it is included in the redisplay area checked at that time, that vector data is displayed and other The investigation of the necessity of display in the display target area (that is, whether or not it is included in the display target area) is discontinued, and the investigation is started on whether or not the next vector data is included in the display target area. There is a characteristic in the place where it is made.

〔Effect of the invention〕

As explained above in detail, the window redisplay method of the present invention is a method for displaying graphic data in multiple windows, and when a certain window is deleted, some of the graphics in the multiple windows below it are When redisplaying data, means for organizing and integrating multiple redisplay areas specified for each window, and for all graphic data unique to each window, the redisplay area is organized and integrated. In the process of searching for whether or not certain graphic data exists within the redisplay area that has been organized and integrated,
When displayed in a specific redisplay area in the integrated redisplay area, the search for other unexamined redisplay areas is interrupted, and the next figure data is checked to see if it exists in the above redisplay area. Since it is designed to move on to search processing, −
Once the decision is made to display the data once, there is no need to investigate whether to perform redisplay processing on other redisplay areas.
Redisplay processing is sped up. Furthermore, by organizing and integrating the display areas, it is possible to reduce the area to be processed. Furthermore, since one vector data is displayed only once, the redisplay process is also simplified.
