Description

[0001]
[Industrial application fields]
The present invention relates to a link control method of a hypertext system used when setting a link in a hypertext system.
[0002]
Currently, for example, a document created by a word processor or the like is stored in a hierarchical directory (Directory). However, it is pointed out that there is a limit in a hierarchical directory when managing such documents.
[0003]
A hypertext system is known as one that goes beyond hierarchical directories. However, since the hypertext system is difficult to operate, the user who creates the hypertext and the browser (program for displaying information) are currently separated.
[0004]
In operating the hypertext system, a particularly bottleneck is an operation of associating a node called a link with a node (node: object that can be associated).
[0005]
Therefore, it has been desired to simplify the link setting operation in the hypertext system.
[0006]
[Prior art]
12A and 12B are explanatory diagrams of the prior art. FIG. 12A is a display screen example 1 and FIG. 12B is a display screen example 2. In FIG. 12, 1 is a menu, 3 is a link destination selection window, 4 is a node list section, 5 is a setting section, and 6 is a cancellation section.
[0007]
Conventionally, a hypertext system (Hypertext System) has been known as a system that stores various types of information in a file and searches and uses the information.
[0008]
Character data (text data) is stored in the hypertext system file, and the character data includes words and phrases in the sentence, headings attached thereto, and a table of contents collecting the headings. Yes.
[0009]
At the time of information retrieval, it is configured so that necessary character data can be extracted by setting a link and tracing the above-mentioned words and headings. A hypertext link setting method will be described below.
[0010]
When setting a link, first, the menu 1 is displayed on the display screen, and the link source node is selected from the menu 1.
For example, if the selected link source node is “node # 1”, window # 1 is displayed on the display screen as shown in FIG. 12A after the link source node is selected. In this window # 1, the contents (ABC...) Of the node # 1 are displayed.
[0011]
Next, when a link is selected from the menu 1 on this screen, a link destination selection window 3 for selecting a link destination node is displayed as shown in FIG. 12B. In the link destination selection window 3, a node list part 4, a setting part 5, and a cancel part 6 are displayed.
[0012]
The node list part 4 displays link destination nodes (for example, node # 2 to node # 5), and one of these nodes can be selected.
The setting unit 5 is for setting the node selected by the node list unit 4, and the cancel unit 6 is for canceling the node selected by the node list unit 4.
[0013]
For example, when node # 2 is selected in the node list unit 4 and then the setting unit 5 is designated, the node # 2 is set as the link destination node.
In this way, the link setting of the link source node and the link destination node can be performed.
[0014]
[Problems to be solved by the invention]
The conventional apparatus as described above has the following problems.
When a link is set in a conventional hypertext system, a link source node is first selected, and then a link destination node is selected.
[0015]
Therefore, it is necessary to always select the link source node and the link destination node (at least the selection operation is required twice), which is troublesome.
An object of the present invention is to solve such a conventional problem and to link displayed nodes with one operation in a hypertext system so as to improve operability at the time of link setting. To do.
[0016]
[Means for Solving the Problems]
FIG. 1 is a diagram for explaining the principle of the present invention. In FIG. 1, the same components as those in FIG. 9 is a display device, 16 is a window management unit, 17 is a browser unit, 18 is a node management unit, 19 is a window control block, 20 is a window management table, 21 is a node, 22 is a link control block, and 23 is data. Show.
[0017]
In order to solve the above-mentioned problems, the present invention is configured as follows.
That is, the present invention focuses on the fact that in a hypertext system, if multiple windows are used, a plurality of nodes can be displayed at the same time, and the simultaneously displayed nodes are often related in one operation. The displayed nodes can be linked to each other, and the configuration is as follows.
[0018]
(a) : A window control block 19 having control information related to a window on the display screen, a window management unit 16 capable of controlling a plurality of windows, a link control block 22 having link information, and a node 21 composed of data 23 In a hypertext system including a node management unit 18 that performs management and a browser unit 17 that manages a window management table 20 composed of window numbers and node names, a current indication is displayed when a user instructs a link. ing For each node A hypertext system link control method for obtaining a node name from the window management table 20 and setting link information in a link control block 22 of the node.
[0019]
(b) : The above configuration (a) In the hypertext system link control method, the hypertext system link control method of setting a link according to the display order by referring to "display order information" indicating the upper and lower sides of the window of the window control block 19.
[0020]
(c) : The above configuration (a) In the link control method of the hypertext system, information regarding windows such as “relative position of window” and “window size” calculated from the display position of the window in the window control block 19 is set when the link is set. A hypertext system link control method that reproduces the physical relationship of nodes when displaying (browsing) on a screen by including the setting in the link control block 22.
[0021]
[Action]
The operation of the present invention based on the above configuration will be described with reference to FIG.
(1) : The above configuration (a) Is as follows. On the display screen of the display device 9, for example,
Assume that window # 1 and window # 2 are displayed.
[0022]
In this case, the contents of node # 1 are displayed in window # 1, and the contents of node # 2 are displayed in window # 2.
In this state, in the window management table 20, the node name corresponding to the window number 1 is the node # 1, and the node name corresponding to the window number 2 is the node # 2.
[0023]
Here, when the user selects a link from the menu on the display screen, the hypertext system operates as follows.
The node management unit 18 obtains the name of the node being displayed by inquiring the browser unit 17 about the name of the node currently being displayed.
[0024]
The node management unit 18 links the node 21 corresponding to the node name obtained from the browser unit 17 by setting a node name other than its own node name in the link destination node name field of the link control block 22.
[0025]
In this case, since the node # 1 and the node # 2 are obtained, the node # 1 side uses the node # 2 as the link destination node name of the link control block 22 of the node, and the node # 2 as the link destination node name. The node sets node # 1.
[0026]
By performing the above control, a link can be set with a single operation for the nodes # 1 and # 2.
(2) : The above configuration (b) Is as follows. For example, assume that the contents of node # 1 are displayed on window # 1, the contents of node # 2 are displayed on window # 2, and the contents of node # 3 are displayed on window # 3 on the display screen.
[0027]
The window display order is assumed that window # 1 is at the top, window # 2 is below it, and window # 3 is at the bottom.
When the user selects a link from the menu in this state, the system operates as follows.
[0028]
The node management unit 18 inquires of the browser unit 17 about the name of the node that is currently displayed. Further, the node management unit 18 inquires of the window management unit 16 about the display order of the window # 1, the window # 2, and the window # 3.
[0029]
The node management unit 18 sets a link in the link destination node name field of the link control block 22 for the node corresponding to the node name obtained from the browser unit 17.
[0030]
In this case, the node management unit 18 displays on the window # 1 because the window # 1 is the top and the window # 2 is the bottom in the display order based on the display order information obtained from the window management unit 16. A link is set from the current node # 1 to the node # 2 displayed in the window # 2. Similarly, a link is set between node # 2 and node # 3.
[0031]
As described above, the link setting between the node # 1 and the node # 2 and the link setting between the node # 2 and the node # 3 can be performed by one operation.
(3) : The above configuration (c) Is as follows. For example, assume that node # 1 is displayed in window # 1 of the display screen and node # 2 is displayed in window # 2.
[0032]
In this state, when the user instructs a link, the following processing is performed.
The node management unit 18 inquires of the browser unit 17 about the name of the node that is currently displayed.
[0033]
At the same time, the node management unit 18 inquires of the window management unit 16 about the display positions of the window # 1 and the window # 2. From the inquiry result, the relative position of window # 2 from window # 1 is obtained. Further, the node management unit 18 inquires of the window management unit 16 about the size of the window # 2.
[0034]
The node management unit 18 sets a node name other than its own node name in the link destination node name field in the link control block 22 of the node corresponding to the node # 1 and the node # 2 obtained by the browser unit 17, and (a) The relative position of window # 2 and the size of window # 2 are also set.
[0035]
In this way, when browsing (displaying), the window display position and the contents of the window size are displayed using the window relative position information and the window size information set when linking. Can be reproduced in the same physical situation as when linked.
[0036]
As described above, the displayed nodes can be linked with one operation. Therefore, the operability at the time of link setting can be improved.
