Abstract

PURPOSE:To allow plural user programs to designate window attribute constituting elements by using a window attribute data base to facilitate generating user programs which indicate generation of windows. CONSTITUTION:After registration of window WND attributes to a WND attribute data base 7 is completed, a WND name is designated by a user program 2 to indicate generation of WND. A WND attribute analyzing mechanism 4 retrieves the pertinent WND name from a WND name list 10 of the data base 7. It is decided whether the WND attribute of this WND name is that of a slave or not based on an identifier stored together with the WND name. If it is not the WND attribute of a slave, a pointer stored in the list 10 is used to take out a pertinent entire set of WND attribute constituting elements from a WND attribute entity 8. This set is given to a WND generating means 5, and the means 5 generates WND on a display device 6 in accordance with the given set of WND attribute constituting elements.

Description

[Detailed Description of the Invention] C. Industrial Application Field] The present invention relates to a window generation method using a window attribute database, and particularly to a window generation method for generating a window using a window attribute database in a computer system having a multi-window function. Regarding the method.

[Conventional technology]

In an electronic military aircraft system with a multi-window function, in order to generate a window on the display device, various parameters such as the window size, font size within the window, color of the window frame, and shape of the cursor within the window must be set. It is necessary to determine all the components of window attributes (hereinafter referred to as window attribute components).

Conventionally, in this type of window generation method, in order to determine all the window attribute components required for window generation, the individual user program that instructs window generation must determine all the window attribute components at the time of window creation. It specified a large number of arguments.

(Problems to be Solved by the Invention) In the conventional window generation method described above, a large number of arguments are specified from the user program when a window is generated. This has the disadvantage that it is cumbersome to create a user program, as it must be written each time a window is generated.

Another drawback is that specifications of window attribute components created for a certain program cannot be used by other user programs.

A further disadvantage is that some of the window attribute components cannot be easily changed by the end user.

In view of the above, an object of the present invention is to facilitate the creation of a user program that instructs window generation by using a window attribute database, and to specify multiple window attribute components once created. The object of the present invention is to provide a window generation method using a window attribute database that can be shared by user programs.

[Means for solving problems]

The window generation method using the window attribute database of the present invention includes a window attribute database for registering window attributes, and all window attribute walls for registering window attributes in this window attribute database.
a window attribute analysis mechanism that searches and analyzes window attributes registered in the window attribute database; and window generation means that generates a window based on the window attributes analyzed by the window attribute analysis mechanism.

[Effect]

In the window generation method using the window attribute database of the present invention, the window attribute database registers the window attributes, the window attribute registration mechanism registers the window attributes in the window attribute database, and the window attribute analysis mechanism causes the window attributes to be registered in the window attribute database. The attributes are searched and analyzed, and the window generation means generates a window based on the window attributes analyzed by the window attribute analysis mechanism.

〔Example〕

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

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.9 The window generation method using the window attribute database of this embodiment is implemented by a user who instructs registration, modification, and deletion of window attributes in the window attribute database 7. A program 1, a user program 2 that instructs the generation of a window based on the window attributes registered in the window attribute database 7, and a user program 2 that instructs the window attribute registration, modification, and deletion in the window attribute database 7 according to instructions from the user program 1. a window attribute registration mechanism 3 that searches and analyzes window attributes registered in the window attribute database 7 according to instructions from the user program 2; window generation means 5 for generating a window on the display device 6 based on the window generation means 5;
The display device 6 includes a display device 6 for generating windows, and a window attribute database 7 for registering window attributes.

The window attribute database 7 includes a window attribute entity 8 that indicates the window attributes of a window, a window attribute genetic relationship 9 that indicates the genetic relationship of window attributes between windows, and a window name list 10 that registers window names, etc. It is.

Referring to FIG. 2, a plurality of window names are registered in the window name list IO. The window attribute entity 8 also includes a window attribute component entire set 81 that includes all window attribute components that define window attributes, and a window attribute component difference that includes some window attribute components that define window attributes. A set 82 is registered.

Furthermore, window attribute genetic information 91 between windows is registered in the window attribute genetic relationship 9.

Window attributes are broadly classified into window types that can be parents and child window types. Now, as shown in Figure 2, if the window attribute to the window name is the window type that can be the parent,
The window master includes an identifier indicating that the window attribute may be a parent, and a pointer indicating the entire set 81 of window attribute components in the window attribute entity 8. Also, if the window attribute of window name B is the child window type, then window name B
Inside is an identifier indicating that it is a child window attribute,
A pointer pointing to a window attribute component difference set 82 in the window attribute entity 8 and a pointer pointing to genetic information 91 in the window attribute genetic link 9 are included.

Next, the operation of the window generation method using the window attribute database of this embodiment configured as described above will be explained.

When an instruction to register window attributes in the window attribute database 7 is issued from the user program l,
The window attribute registration mechanism 3 is activated and the window attributes are registered in the window attribute database 7.

First, when registering a completely new window attribute,
The user program 1 specifies the window name and all the window attribute components constituting the window attribute, and instructs the window attribute registration mechanism 3 to register the window attribute. Upon receiving the instruction, the window attribute registration mechanism 3 registers the entire set 81 of window attribute components including all the window attribute components specified in the window attribute entity 8 of the window attribute database 7, and also The specified window name, the identifier indicating that it is a window attribute that can be a parent, and the entire set of window attribute components 8
A pointer to 1 is registered.

In addition, when registering a child window attribute using a window attribute already registered in the window attribute database 7 as a parent, the user program 1 uses the window name given to the child window attribute and the window of the parent window attribute. An instruction to register the window attribute is given to the window attribute registration mechanism 3 by specifying the name and the difference indicating the changed part of the child window attribute component with respect to the parent window attribute component. Upon receiving the instruction, the window attribute registration mechanism 3 registers a window attribute component difference set 82 containing the differences of the window attribute components specified in the window attribute entity 8 of the window attribute database 7, and registers a window attribute component difference set 82 that includes the differences of the window attribute components specified in the window attribute entity 8 of the window attribute database 7. Genetic information 91 indicating the parent is registered in , and the window name of the child window attribute, an identifier indicating the child window attribute, and a pointer to the window attribute component difference set 82 are added to the window name list IO. Genetic information 9
A pointer to 1 is registered.

Note that the user program 1 can instruct not only the registration of window attributes in the window attribute database 7 but also change and deletion, and based on this instruction, the window attribute registration mechanism 3 registers the window attributes in the window attribute database 7.
You can change or delete window attributes registered in .

After registration of window attributes in the window attribute database 7 is completed, when the user program 2 specifies a window name and instructs generation of a window, the window attribute analysis mechanism 4 registers the window attribute in the window attribute database 7.
The window name list 10 is searched for the corresponding window name, and it is determined whether the window attribute of this window name is a child window attribute based on the identifier stored together with the window name. If it is not a child window attribute, the entire set 81 of the corresponding window attribute components is retrieved from the window attribute entity 8 using the pointer stored together with the integer in the window name list lO, and the set of window attribute components is retrieved. It is given to the window generating means 5 as a.

In addition, if it is a child window attribute, the genetic information 9 is selected from the window attribute genetic relationship 9 using the pointer stored together with the window name in the window name list lO.
Extract 1 0 Next, obtain the window name of the parent window attribute from the extracted genetic information 91, search for this window name in the window name list 10, and use the pointer stored with the corresponding window name. Then, the window attribute component difference set 82 is extracted from the window attribute entity 8 using the pointer stored together with the child window name in the window name list 10. Next, the extracted entire set of window attribute components 81 and the window attribute component difference set 82 are analyzed to create a correct set of window attribute components of the child window attributes, and this set of window attribute components is used as the window attribute component set. It is given to the generating means 5.

The window generation means 5 generates a window on the display device 6 according to a given set of window attribute components.

In this way, in this embodiment, it is possible to register a window type with arbitrary window attributes from the user program 1. In addition, it is possible to register a new window type by changing part of an already registered window type. In this case, only the difference, which is the changed part of the window attribute component, is registered using the already registered window type as the parent. Just specify it.

It has been explained that the user program 2 can only generate the corresponding window by specifying the window name to the window attribute analysis mechanism 4, but the user program 2 can also specify the window name and the difference between the window attribute components. Then, without registering the window attribute component difference set 82 in the window attribute entity 8, the window attribute analysis mechanism 4 creates a set of window attribute components of the child window attributes and directly generates the desired window. It is also possible to

〔Effect of the invention〕

As explained above, by providing the GF of the present invention and the window attribute database, there is an effect that it becomes easy to specify window attribute components in a user program that instructs window generation.

In addition, window attributes can be changed extremely easily, and end users can easily create windows of a wide variety of window types.

Another advantage is that the created window type can be shared by multiple user programs.
