Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] The present invention relates to a display / input priority management method for managing display / input priorities of objects such as figures, and recognizes the correspondence between each object and its display / input priority. In addition to facilitating the display / input processing in the order of priority and the priority order, it is also intended to facilitate the recognition of the attributes of each object and the change of the object attribute table when the display / input priority is changed. In a display / input priority management method for managing display / input priority, a display / input priority table in which objects are arranged in the display / input priority order and an attribute of each object are stored. The display / input priority order of the target object is managed by using the target object attribute table together. When the display / input priority order of the target object is changed, the display / input priority table is changed, and the change obtained at that time is changed. The display / input priority of the attribute table of each change target is changed based on the target and its display / input priority change information.

[Industrial applications]

The present invention relates to a display / input priority management method for managing the priority of display of an object such as a graphic displayed on a display unit and / or input (hereinafter, referred to as display / input).

[Conventional technology]

In computer graphics, display processing for displaying objects such as a plurality of figures on a display unit and input processing for extracting one object from the plurality of objects displayed on the display unit are performed.

When a plurality of objects are displayed on the display unit, as shown in FIG.
It is common practice to display an object with a higher priority in preference to an object with a lower priority. In the case of FIG. 5 (A), the priority of the object is the highest, and in the following, the order of the object → the object.

There are the following two methods for managing the display priority of a plurality of objects.

(A) Management method using display priority table In this management method, as shown in FIG. 6 (A), each object is managed using a display priority table arranged in the order of display priority. When an object is displayed, by referring to this display priority table, the name of the object in that order can be directly known from each display priority, so that the display can be easily made as shown in FIG. 5 (A). can do. Conversely, the display priority can be directly known from the object name.

(B) Management method using object attribute table In this management method, as shown in FIG. 6 (B), an attribute table is provided for each object, and display priorities are set as attributes of the object itself, and other attributes are set. It is stored and managed together in the attribute table together with the attributes such as cotton width and color.

At the time of displaying an object, these attribute tables are referred to, the objects having the lowest display priority are searched in order, and displayed as shown in FIG. 5 (A).

Next, the input processing will be described. When the objects are displayed in an overlapping manner, if the objects are opaque, it is clear that the pointers P, Q and R point to the objects and, respectively, as shown in FIG. 5 (A). It is.

However, if each object is transparent, it becomes as shown in FIG. 5 (B), so it is unclear which of the same pointer P indicates the object 〜, and the pointer Q indicates which of the object and It is unknown whether to instruct. Also in such a case, in order to take out one object, the following two methods (a) 'and (b)' similar to the management of the display priority order of the object are performed. Input priority management is performed.

(A) 'Management method by input priority table In this management method, input priority is given to each object, and each object is arranged in the order of the input display priority as shown in FIG. 6 (C). It is managed by the input priority table. In the case of FIG. 6 (C), the input priority is lower in the order of the object →→. Note that the display priority and the input priority may be different.

(B) 'Management method using object attribute table This management method, like the display priority management method, sets the input priority along with other attributes in the object attribute table shown in FIG. 6 (B). Store and manage.

The object having the highest input priority is extracted by referring to the input priority table or the object attribute table. For example, in FIG. 5 (B), when point P is pointed, the object having the highest input priority among the objects to becomes the input object,
For example, it highlights and instructs the operator. When the point Q is pointed, the object and the object having the higher input priority among the objects are selected as the input object and highlighted.

If the priority of both display and input is managed, it is managed by a method using a display and input priority table or a method using an object attribute table in which both display and input priority are stored.

[Problems to be solved by the invention]

Conventional display / input priority management methods include (a) a management method using a display / input priority table and (b) a management method using an object attribute table, as described above. (A) The management method using the display / input priority table is to know the display / input priority of each object, and conversely, to know the object name corresponding to each display / input priority.
Although it is easy to display or input each object in the order of priority, on the other hand, when obtaining individual attributes of each object, it is necessary to search other attribute information storage units for attributes other than priority. Therefore, there is a problem that the search is troublesome.

On the other hand, in the method using the object attribute table in FIG. 2B, it is easy to obtain the attribute of each object, but on the other hand, it takes time and effort to search for the correspondence between each object and its priority, and the priority There is a problem that it is not easy to display or input in order. When the display or input priority is changed, the display or input priority is set by relative designation such as "the display (or input) priority of the object X is higher than the display (or input) priority of the object Y". However, in the case of such a relative designation, it is necessary to separately obtain the display (or input) priority order after the range of the object that causes a change in the display (or input) priority order. However, there is a problem that it takes time to change the object attribute table.

The present invention facilitates the recognition of the correspondence between each object and its display / input priority, thereby facilitating the display / input processing in the order of priority, and also facilitates the recognition of the attribute of each object, and the display. It is an object of the present invention to provide a display / input priority management method improved so that an attribute table can be easily changed when the input / input priority is changed.

[Means for solving the problem]

In the conventional display / input priority management methods (a) and (b), as can be seen from the above description, one of the advantages and disadvantages is the other. Therefore, if a management method can be obtained only by the advantages of both management methods, a display / input priority management method having both advantages can be realized. The present invention, from this viewpoint,
By using the display / input priority table and the object attribute table together, it has the advantages of both management methods,
The object attribute table can be easily changed when the display or the input priority is changed.

Hereinafter, means employed by the present invention to solve the above-described problem will be described with reference to the principle diagram of FIG.

In FIG. 1, reference numeral 111A denotes a display priority order table in which objects are arranged in the order of their display priority order.
Reference numeral 111B denotes an input priority table in which objects are arranged in the order of the input priority.

112 _i (i = 1.2...) Is an object attribute table, which is provided corresponding to the object i (i = 1, 2,...) And stores information relating to the attributes of the object including the display / input priority order. Is done.

The display / input priority management method of the present invention manages display / input priority using both the display / input priority table 111A / 111B and the object attribute table 112, as follows. It is composed of

That is, in a display / input priority management method for managing display / input priorities of objects, (a) a display / input priority table in which each object is arranged in the display / input priority order ( 111A / 111B) to manage the correspondence between each object and its display / input priority and the display / input processing, and (b) the object in which the attribute information of each object including the display / input priority is stored The attributes of each object are managed by the object attribute table (112 ₁ etc.). (C) When the display / input priority of the object is changed, the display in the display / input priority table (111A / 111B) In addition to rearranging the input priorities in accordance with the change order, display based on the information on the display / input priorities that have changed the display / input priorities obtained by the change processing and the display / input priorities after the change. / Enter Performs change processing of the search and the display / input priority attribute table of the object which caused the changes in the priority, as configured.

[Action]

The operation of the present invention will be described with reference to FIG. 1 by taking a display priority management method as an example.

There are 5 objects, and the display priority is
Assuming that the order is higher in the order of →→→→, the display priority table 111A stores the object names,..., In the order of priority 1 to 5, as shown in FIG. Rank 1 of the object is the lowest, and rank 5 of the object is the highest. By referring to the display priority table 111A, the correspondence between each object and its display priority can be directly known, and each object can be easily displayed in the order of its display priority.

Each object attribute table 112 _i (i = 1 to 5) stores the attribute of the corresponding object i (i = 1 to 5). As shown in FIG. 1 (C), 3, 4, 2, 5, and 1 are stored as the display priority of the object to. By using this object attribute table, all attributes of each object can be immediately known.

Next, a description will be given of a process of changing the display priority order table 111A when the display priority order of the target object is changed and the respective object attribute tables in which the display priority order is changed. It is assumed that a change instruction has been given so that the display priority of the object is lower than the display priority of the object. in this case,
The display priorities of all objects (one of the objects in FIG. 1 (A)) having a display priority intermediate to that of the object are also changed at the same time.

By rearranging the display priorities in the display priority table 111A in accordance with the designated change order, the objects corresponding to the display priorities 1, 2, and 3 become as shown in FIG. Each is changed (details of the changing method will be described in the embodiment section).

By this display priority table changing process, information on the object whose display priority has been changed and the display priority after the change can be obtained, so that the process of changing the object attribute table can be easily performed. That is, the object information whose display priority has been changed from this information is
And the object attribute table
112 _1, 112 ₃ and 112 ₅ accesses, by changing in accordance with the display priority order information after the change the display priority, easily object attribute table as shown in FIG. 1 (C) changing process It can be performed. That is, the display priority of the object and the display priority of 3, 2, and 1 is changed to 1, 3, and 2 respectively (details of the change method will be described in the section of the embodiment). Thus, the combined use of display priority order table 111A and the object attribute table ₁₁₂₁ and the like, it is possible to change the processing of the object attribute table easily and quickly in case of change in the display priority order .

So far, we've described how to manage display priorities.
The management method of the input priority table and each object attribute table in the input priority management method, and the change processing of both tables when the input priority is changed, are the same as in the case of the display priority management method. Done.

As described above, the display / input priority order is managed using both the display / input priority order table and the respective object attribute tables. Therefore, at the time of display / input, each object and its object are determined from the display / input priority order table. The correspondence of the display / input priority can be directly known, and the display / input processing can be performed easily and promptly.

If the display / input priority is changed, the display / input priority is changed by the display / input priority table change processing.
Since the information on the input priority is obtained, it is possible to easily and promptly change the necessary object attribute table based on this information.

It is explanatory drawing of the change process of a display priority order table and an object attribute table. FIG. 5 is an explanatory diagram of the display method of a plurality of objects already described.

(A) Configuration of Implementation Device In FIG. 2, reference numeral 11 denotes a priority management unit, which internally includes a display priority table 111A and an input priority management table.
It has 111B and object attribute tables 112 _{0 to} 112 _n−1 and manages display / input priority and attributes of each object.

Reference numeral 12 denotes a control unit, which performs display processing, input processing,
The processing of changing the display priority management table 111A, the input priority management table 111B, and each object attribute table whose display / input priority has been changed is performed.

Reference numeral 13 denotes a display unit on which each object is displayed according to its display priority.

Reference numeral 14 denotes an input unit for performing various inputs using a keyboard, a mouse, a light pen, and the like, and for instructing a change in display / input priority.

(B) Operation of Embodiment The operation of the embodiment will be described with reference to FIGS.

In the priority management unit 11, the display priority management table 111A, the input priority management table 111B
And attributes of the object name and the object corresponding to the display / input priority to each object attribute table ₁₁₂₀ and the like are stored.

FIG. 3A shows an example of the display priority management table 111A, FIG. 3B shows an example of the input priority management table 111B, and FIG. 3C shows the attribute table 112 ₀ of each object.
And the like.

In the display and input priority, “0” is the lowest, and the higher the number, the higher the priority. The case of 32 objects is shown. In this example, both the display and the input priority are the lowest for the object and the highest for the object. In FIG. 3, the display and input priorities of the respective objects are the same, but the display and input priorities of the respective objects do not need to be the same, and different priorities may be given. it can.

The names in parentheses indicate the names according to PHIGS. Currently, computer graphics are being standardized. One of them is PHIGS (the Programmer's).
s Hierarchical Interactive Graphics System). In the PHIGS graphic data, a set of various elements such as an output basic element, attribute specification, visual field index specification, modeling conversion, label and data insertion has a hierarchical structure. PHIG
The "field of view" in S indicates one display window frame or window, and corresponds to the object in the description so far.
Further, the visual field index corresponds to the object name.

By referring to the display (or input) priority management table 111A (or 111B), at the time of display (or input), the display (or input) priority can be directly obtained from the object name. , The object name can be directly obtained from the display (or input) priority. In addition, each object can be displayed (or input) easily and promptly in the order of the display (or input) priority. Hereinafter, display processing, input processing, and table change processing will be described.

(1) Display Processing When displaying each object, the control unit 12 refers to the display priority management table 111A and displays the objects on the display unit 14 in ascending order of display priority. At this time, objects having a higher display priority are displayed with priority over objects having lower display priorities.

Assuming that the objects to be displayed are and, the display priority is lower in the order of the objects →→.
As shown in FIG. 7A, the object is displayed at the highest position, and the object is displayed at the lowest position.

(2) Input Processing It is assumed that the respective objects and are now displayed in a transparent window on the display unit 13 as shown in FIG. 5 (B). In this embodiment, the input priorities of the objects are set to be lower in the order of the object →→.

The input unit 14 is used to point to an input point using a cursor or a light pen. When the point P is input, the coordinates of the point P are sent from the input unit 14 to the control unit 12.

The control unit 12 detects each object having the coordinates of the point P therein. Next, referring to the input priority table 111B of the priority management unit 11, when detecting that there is an object having the highest input priority, the display unit 13 is instructed that there is an input object. Upon receiving this instruction, the display unit 13 highlights the target object and notifies the operator that the target object has been selected.

Similarly, when the point Q is pointed, the target object and the target object having the higher input priority are selected and highlighted.

(3) Table Change Process The process of changing the display priority management table 111A and the corresponding object attribute table when the display priority is changed will be described with reference to FIG.

Now, there are five objects, and the display priority order of the objects is as shown in FIG. 1 (a).
It is assumed that 1 → 2 → 3 → 4 → 5 in the order of →. Also,
It is assumed that the change of the display priority is set by relative designation as in PHIGS, and the input unit 14 is set so that the display priority of the object is lower than the priority of the object.

When receiving the instruction to change the display priority from the input unit 14, the control unit 12 performs a process of changing the display priority table 111A and the attribute table of each object whose display priority has been changed in the following procedure.

(A) As shown in the process S ₁ 4 (a), the display priority order table 11
The object (display priority 3) is taken out from 1A (evacuated to a work area not shown), and the object having the display priority 2 lower than the object by one is moved to the place where the object was. And its display priority is 3. Then, access the attribute table 111 ₃ of the object a change has occurred in the display priority, to change the display priority 2-3.

As shown in (b) processing S ₂ FIG. 4 (b), transferring the object was displayed Priority 1 one lower than the object in a the place of the object, and 2 the display priority I do. Then, access the attribute table 112 ₅ of the object a change has occurred in the display priority, to change the display priority from 1 to 2.

(C) as shown in process S ₃ Figure 4 (c), where there was the object,
An object that has been outside until then is put in, and its display priority is set to 1. Then, access the attribute table 112 ₁ of the object a change has occurred in the display priority, to change the display priority from 3 to 1.

As described above, when the change of the display priority is set by the relative designation, the display priority table can be changed by sequentially obtaining all the objects having the change in the display priority, and The display priority of each object attribute table can be changed. Similarly, when the change of the display priority of any two objects among the objects more or less than five is set by the relative designation, the change is similarly made to the display priority table 111A and the display priority. The display priority of each object attribute table that has occurred can be changed.

As described above, one embodiment in the case where the display priority has been changed has been described. The input priority of the object attribute table can be changed.

〔The invention's effect〕

As described above, according to the present invention, the following effects can be obtained.

(1) Since the display / input priority is managed by using both the display / input priority table and each object attribute table, at the time of display / input, each object and its display are displayed from the display / input priority table. The user can directly know the correspondence between the input / input priorities, and can easily and quickly perform the display / input processing.

(2) When there is a change in the display / input priority, the display / input priority of each object whose display / input priority has been changed by the display / input priority table change processing and the display / input priority after the change are changed. Since the information is obtained, the necessary change processing of each object attribute table can be easily and promptly performed based on this information.
