DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
The present invention is described in detail hereinafter with reference to the accompanying drawings. FIG. 1 is a functional block diagram showing one embodiment of a method of displaying a right click menu screen of an operation monitoring apparatus, according to the present invention. In the figure, elements identical to those of the related-art configuration that are described with reference to FIG. 8 are each denoted by a like reference numeral, thereby omitting description thereof.
In FIG. 1, upon execution of right click of an object 101 on an operation-monitoring screen 100 of an operation monitoring apparatus according to the present invention, an object name of the object 101 is delivered to a retrieval means 200.
The retrieval means 200 retrieves an individual menu definition file 301 of an object file holding means 300, and a common menu definition file 302 that is the same as the individual menu definition file 301 except that identification data is embedded and described therein, by making use of an object name acquired as a key, thereby extracting a file wherein the object name is in agreement with an identification data of the common menu definition file, whereupon display information of the file is notified to a screen display means 30.
The screen display means 30 displays a right click menu screen 102 on the operation-monitoring screen 100 on the basis of the display information acquired from the retrieval means 200. A right click menu unique to the object 101 as selected is displayed on the right click menu screen 102 displayed at this point in time.
The individual menu definition file 301 of the object file holding means 300 is made up of a plurality of definition files edited on an object-by-object basis, and object names are affixed to the respective definition files, serving as respective file names.
FIG. 2 is a view showing a display example of the right click menu screen 102 according to the present invention. The menu is of a hierarchical structure wherein a reference right click menu B in a first hierarchical layer is displayed after a select object name A, and further, a submenu C is displayed in a second hierarchical layer.
The reference right click menu B is identical to the general-purpose menu in common with all the objects, as explained with reference to FIG. 8 for describing the related-art method, and the submenu C corresponds to the right click menu unique to the select object IFIC200 in FIG. 8.
FIG. 3 is a flow chart showing a procedure for displaying the right click menu screen according to the present invention. Upon startup of processing, the retrieval means 200 acquires an object name allocated to a right click location on the right click menu screen 102 to be defined (step S1).
In step S2, the retrieval means 200 executes retrieval of a file under the name of “object name.csv” under a specified folder of the object file holding means 300. If the file is found during a branching processing in step S3, the processing proceeds to step S4 where a menu-construction processing is executed. The menu-construction processing will be described in detail with reference to FIG. 7 later on.
If an effective menu definition exists in a branching processing in step S5, the processing proceeds to step S6 where processing for replacement of a special keyword is executed, and the right click menu is displayed in step S7, thereby completing the processing in step S8. If a file in agreement with the file under the name of “object name.csv” is not found in the branching processing in the step S3, and if the effective menu definition does not exist in the branching processing in step S5, the processing is completed without menu definition (step S9).
FIG. 4 shows an example of a menu definition information format according to the present invention. Menu information necessary for executing a menu selected by displaying the right click menu is expressed by a character string record in the form of CSV (comma separation value) in three columns, comprising hierarchy, menu display item, and execution command definition, per one menu item. The following table shows items in the respective columns, and explanation about the contents thereof.

the case with related-




art technologies, a

A menu definition file described in a predetermined format is one file against one object, and an object name+extension (“.csv”) is affixed to the file. For example, a definition file name against a tag IFIC200 is IFIC200.csv. A group of these CSV files are all preserved under a specified folder.
When the retrieval means 200 has acquired an object name, the retrieval means 200 retrieves a CSV file having an object name designated under a predetermined folder by use of the function of a standard file system mounted on an operating system without use of a commercial database system and so forth. By so doing, a right click menu function can be realized with low cost.
A PC of the latest model has a performance such that even if a CSV file having a specific object name is retrieved out of several tens of thousands of files, the PC can attain retrieval in about 100 ms, and is equipped with sufficient retrieval capability for display of the right click menu careen.
FIG. 5 is a view showing an example of description of a hierarchy menu definition file according to the present invention, and an example of display of the screen thereof. In a hierarchy menu definition file (A) having an object name TagName001.csv, Parent Menu as the main menu in a first hierarchical layer is described, being followed by Child Menu items A, B, C, in a second hierarchical layer.
The display result of the right click menu screen of the hierarchy menu definition file (A) having an object name TagName001.csv shows that the main menu in the first hierarchical layer is displayed in (B), and submenu in the second hierarchical layer is displayed in (C).
FIG. 6 is a view showing an example of description (A) of the individual menu definition file and the common menu definition file, according to the present invention, and examples of displays (B), (C) of the respective screen thereof. The common menu definition can be designated by describing “0” in the hierarchy in the column 1.
The common menu definition is definition shared by a plurality of menus. Accordingly, all the menus referred to can be concurrently changed by changing the common menu definition. A unique identification data, for example, Common001.csv, is affixed to the common menu definition file as well to be preserved under a predetermined folder.
As shown in (A) of FIG. 6, a lower-level Context Folder F2 is placed below a higher-level Parent Folder F1, and further, a Common Folder F3 is placed below the Context Folder F2, whereupon the individual menu definition file 301 is preserved under the Context Folder F2, and the common menu definition file 302 is preserved under the Common Folder F3.
An individual menu definition file having an object name TagName002.csv is provided with description where a common menu definition file (file name: Common001.csv) having “0” in the hierarchy, and menu items X, Y, Z, is embedded in the lowest line. The retrieval means 200, upon detection of this description, retrieves the common menu definition file under the Common Folder F3, and extracts a common menu file having a file name Common001 to be delivered to the screen display means 30.
Menu items of an individual definition portion of the individual menu definition file are displayed in a front-stage (B) of the right click menu screen 102 displayed on the operation-monitoring screen 100, and the menu items X, Y, Z of a common definition portion of the common menu definition file are displayed in a subsequent-stage (C) of the right click menu screen 102.
FIG. 7 is a flow chart showing a detailed procedure for the menu-construction processing according to the present invention, shown in the step S4 of FIG. 3. Upon startup of the processing, an individual menu definition is read in step S1, and if a next line exists in menu definition during a branching processing in step S2, the processing proceeds to step S3 to thereby make a decision on effectiveness.
If neither a line to be ignored, nor invalid definition exists during a branching processing in step S4, the processing proceeds to step S5 to refer to a common menu, and if the common menu does not exist, the processing proceeds to step S6 to add an individual menu item.
Further, the processing proceeds to step S8 via a branching processing in step S7, in the step S8, the case where either the line to be ignored, or the invalid definition exists during the branching processing in the step S4 being inputted, and thereafter, the processing reverts to the step of making a decision on the next line as in the step S2. If the next line exists, the processing via this loop is repeated to be completed in step 9 when the next line disappears. If the common menu exists in the branching processing in the step S5, the processing proceeds to step S10 to read the common menu. If the next line exists in the common menu definition as read in the step S10 during a branching processing in step S11, the processing proceeds to step S12 to make a decision on effectiveness. If neither the line to be ignored, nor the invalid definition exists during a branching processing in step S13, the processing proceeds to step S14 to add a common menu item. Further, the processing proceeds to step S15 where the case where either the line to be ignored, or the invalid definition exists during the branching processing in the step S13 is inputted, and thereafter, the processing reverts to the step of making a decision on the next line as in the step 11.
If the next line exists in the step of making the decision on the next line as in the step S11, this loop is repeated, and the processing proceeds to the branching processing in the step S7 when the next line disappears, thereby reverting to the routine of the construction processing of an individual menu.
Thus, with the processing for displaying the right click menu screen, there is adopted a flow whereby the contents of the individual menu definition are successively interpreted, and upon detection of a reference to the common menu at a midpoint, the common menu file is opened to thereby interpret the contents thereof, reverting to processing for interpretation of the original individual menu definitions upon completion of the above-mentioned.
Now, there are described hereinafter checking of the effectiveness of the individual menu definition executed in the step S3, and checking of the effectiveness of the common menu definition executed in the step S12. In this processing, the following decisions are executed against respective lines (record) in a CSV file. The decisions are basically pursuant to the rule of the definition of the CSV format of RFC4180.
1. Lines to be Ignored
The following lines contained in the individual menu definition files, and the common menu definition file, respectively, are ignored:
a blank line, or a line with white space only
comment (including a line with “#” prefixed thereto, and a line with white space preceding “#”)
However, the context of the line ignored is secured.
2. Invalid Definition
The following lines of the individual menu definition files, and the common menu definition file, respectively, are regarded as invalid definition to be thereby ignored:
record (a blank line is ignored) described in a format not based on RFC4180
record containing a line feed (CRLF or LF) in a character string column
record where the number of columns is other than 3
record where a first column is not at an effective value (0 to 2)
record where a second column is only a blank line, or a line with white space only
record defined at the head of a file, having a first column at 2, and records successively defined thereafter, having a first column at 2
in the case of a record immediately preceding records where a first column is at 2 having a first column at 0, and records successively defined thereafter, having a first column at 2
in the case of a record immediately preceding records where a first column is at 2 having a first column at 1, and invalid definition, and records successively defined thereafter, having a first column at 2
a line (a common definition portion of a common menu definition file) in the common definition file, having a first column (hierarchy) at 0
As described in the foregoing, a highly-flexible right click menu structure according to the present invention is combined with a related-art fixed-type menu structure to thereby enable only necessary part of an individual right click menu to be expanded.
By so doing, it is possible to additionally define only definition related to a necessary object name without preparing the individual menu definitions related to all the objects, respectively, so that the number of steps necessary for definition can be substantially cut back.
In addition, a plurality of operation monitoring stations are enabled to refer to a common menu by placing a folder for storing menu definition files in a server on a network, and by making a shortcut reference to the folder. By so doing, it is possible to eliminate the need for executing file-copying to the operation monitoring stations.
With the present invention, the following advantageous effects can be expected.
(1) It is possible to display right click menus completely different in configuration from each other according to a select object.
(2) Since data is structured simply, and through intuition, menu definition can be described by use of a text editor, and a general-purpose spreadsheet software. Further, because of a simple data-structure, even an end-user is able to easily execute addition/correction of menu definition on an object-by-object basis.

(3) Since all menu definition data are managed under only a specified folder, the present invention can be easily applied to a plurality of units of operation monitoring apparatuses simply by copying of a management folder.

(4) For the retrieval means against the individual menu definition file, or the common menu definition file, use can be made of the standard file system mounted on the operating system, and there is no need for using a particular software, so that a system can be realized at a low cost.

(5) Since the common menu definition is shared between definitions identical in menu structure to each other, it is possible to reduce a maintenance cost as well as a construction cost of the individual menu definition files for massive numbers of objects.

While the present invention has been shown and described with reference to certain exemplary embodiments thereof, other implementations are within the scope of the claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
