Description

  The present invention relates to a graphical user interface system, a graphical user interface generation method, and a program in an information processing apparatus.

  In recent years, a document management system has been used as a system by installing a document management application on a personal computer from a system using a dedicated terminal. A graphical interface (GUI) in a conventional document management system generates a window on a desktop screen when an operation is performed on a document or a folder (hereinafter referred to as data as a whole), and within a frame formed in the window. To display data. When the user selects data, the user selects data displayed in the frame in which the data is displayed using a mouse or the like, and then performs processing for selecting a menu or button for a target operation.

  In other systems, an event that causes data icons to be displayed by dragging and dropping the data icon to the application icon for performing a process for double-clicking the data icon with a mouse or the like or a specific process. , Activate the application selected for the specific data or the application associated with the data to access the data. In addition, as the functions of information processing devices such as personal computers become more sophisticated, and the capacity of hard disk devices has increased, the amount of data that must be managed by the document management system has become enormous.

  For this reason, conventionally, when the data to be displayed does not fit in the frame formed for data display, the user can use the scroll bar formed on the side of the frame until the target data is displayed in the frame. To display the desired data on the screen until the file name is displayed in the frame.

  In addition, processing requests for data have become complicated, and it has become normal for a user to select a plurality of data at the same time and perform processing such as merging and cutting and pasting with a specific application program. When the user selects a plurality of data, if not all the data to be selected are displayed on the screen, the conventional document management system operates the scroll bar while selecting one data, Select the data to be used.

As the above-described conventional GUI system, for example, a system described in JP-A-11-96194 (Patent Document 1) can be cited. The GUI system described in Patent Document 1 identifies and displays a folder in response to selection of a folder in the folder display area on the browser screen, and displays thumbnails of image files in the selected folder in the thumbnail display area. It discloses that a plurality of data is arranged and displayed in a display frame.
JP-A-11-96194

  Although patent document 1 discloses generating a frame in a window and displaying a plurality of data or thumbnails of the data in the generated frame, it is an object to improve the searchability of specific data. However, this does not solve the possibility of the user selecting a plurality of data or improving the efficiency of the operation of reading a plurality of selected data into an application selected at once. That is, it is assumed that the data already selected by the user is invisible from the data display frame as a result of the user performing a scroll operation to search for other target data.

  That is, when all the data that the user wants to use is selected, the display frame displays only the data that fits in the display frame at the current scroll position, and the selected data that has disappeared from the screen due to scrolling is still displayed. There has been a problem that it is not possible to confirm whether or not there is no error in the selection operation such as the data selection sequence, and there is no omission in selection when the last data is selected.

  In addition, in the conventional GUI system, when the data to be displayed in the frame is changed by using the scrolling and page turning function, in order to confirm the invisible data, the scrolling, page turning, and page are reversed again. In this case, there is a problem that data before scrolling in the reverse direction becomes invisible from the display frame in the same manner, and the scroll operation becomes useless, increasing the burden on the user.

  Also, when processing multiple data such as documents and image data into a specific recording unit that is referred to as a folder or directory, for example, scrolling the frame displays the display of the destination folder or directory. When the frame becomes invisible, the user instructs the scroll operation in the reverse direction again while maintaining the data selection, displays the recording unit of the movement / copy destination, and performs an operation such as drag and drop. become. These operations need to be performed while the user maintains the selected state of the data. In addition to the scroll operation, it is necessary to perform a plurality of operations such as recording unit recognition and drag and drop in parallel. There was also the problem of giving a burden.

  In other words, a GUI system, a GUI generation method, a program, and a recording medium that can improve data selection efficiency when a plurality of data are selected and a predetermined process is to be executed collectively. Was needed.

  Further, when a predetermined operation is performed on a plurality of data at once, a GUI system, a GUI generation method, a program, and a recording medium that improve the recognizability of the selected data are required.

  Furthermore, when a user selects a plurality of data and performs a predetermined operation at once, a GUI system, a GUI generation method, a program, and a recording medium that improve user operability by reducing user actions are required. It had been.

  The present invention has been made in view of the above-described problems of the prior art. In the present invention, when selecting data while displaying a plurality of data, in order to display the data selected by the user, the display area such as the original window is further divided into a divided area such as a frame and newly divided. A second divided area is generated as a frame, and the selected data is displayed in the second divided area. The term “display area” means a window or a main display screen formed on the display screen and including a menu bar. The term “divided area” means a frame or a display frame that is formed so as to be inscribed in the display area and displays different data. Further, the term “second divided area” means a display frame that is generated so as to be inscribed in the “divided area” and displays data associated with the “divided area”. Reference as a divided frame. These terms are not particularly limited regardless of application programs, operating systems, etc., as long as they provide the same function. The term “selected data” means data selected by right-clicking, “shift” + clicking, or area selection among data displayed in the frame by the user.

  The display process of the selection data in the divided frames can be executed when the user selects the data in the original frame. In addition, for efficient use of multiple frames, the display processing in the divided frames is controlled so that it does not overlap with the data display in the original frame, and the original frame is converted to the scroll or page break processing. In response to the corresponding selection data being hidden / displayed, the display / hidden control is controlled in divided frames.

  In the present invention, the size of the divided frame is controlled in the range from the maximum size to the deletion in response to the number of data to be displayed in the divided frame, and while the data display area in the original frame is optimized, Make the display more efficient.

  Further, in the present invention, in order to avoid duplicate display, a result set of a set product of the selected data and the data displayed in the original frame is generated, and the selection corresponding to the data identification value included in the result set Display control is performed so that data is not displayed in divided frames. Furthermore, when the user performs a user action such as drag-and-drop on the data displayed in the divided frame, the data selected for the same user action is displayed regardless of whether the data is displayed or hidden in the divided frame. The selection sequence is acquired while being held, and efficient data editing is enabled.

  Furthermore, the present invention provides a GUI generation method, a program, and a recording medium that records the program for realizing the above-described GUI system in an information processing apparatus.

  Hereinafter, the present invention will be described with embodiments, but the present invention is not limited to the embodiments.

An input device 122 such as a keyboard and a pointing device such as a mouse is connected to the I / O bus 118 via a bus such as a USB, and receives inputs and commands from an operator such as a user.

  The CPU 102 is not particularly limited. Specifically, for example, a single core such as PENTIUM (registered trademark) to PENTIUM (registered trademark) IV, PENTIUM (registered trademark) compatible CPU, POWER PC (registered trademark), MIPS, etc. Mention may be made of processors with any architecture, such as multi-core.

  The operating system (OS) to be used is MacOS (trademark), Windows (registered trademark), Windows (registered trademark) 200X Server, UNIX (registered trademark), AIX (registered trademark), LINUX (registered trademark) or other. The appropriate OS can be listed. Furthermore, the GUI system 100 stores and executes an application program written in an object-oriented programming language such as C ++, VisualC ++, VisualBasic, Java (registered trademark), Perl, or Ruby, which operates on the above-described OS.

  FIG. 2 shows an embodiment of functional block 200 of GUI system 100. The functional block 200 of the GUI system 100 is configured by the CPU 102 of the information processing apparatus executing various programs and realizing each functional block on the information processing apparatus. As shown in FIG. 2, the functional block 200 is realized by an OS 202 that manages the overall execution of the GUI system 100 and a compiler, linker, assembler, and the like on the OS, for example, VisualC ++, bytecode, interpreter, and the like. And a programming language module 204 such as JAVA (registered trademark) that provides various functions.

  The programming language module 204 can execute a so-called object-oriented program and can perform multi-window display. Therefore, the programming language module 204 includes a display area controller 206 for managing window generation, layout change, window deletion, and the like. The programming language module 204 also includes an event handler 208 that instructs execution of various processes in response to selection of various icons, hot spots, etc. formed in the window.

  The programming language module 204 receives a mouse event from a window formed on a display by an application program 210, 212, 214, etc., which will be described later, and a key sequence event corresponding to the mouse event, and executes an requested process. Execute a call. The display area controller 206 described above is a general term for functional modules configured by a collection of window control modules such as a window class, a frame class, and a scroll class. In the embodiment shown in FIG. 2, the display area controller 206 further divides a divided area called a display area generation module 206a for generating a window, a frame displayed in the display area, It is shown that it is configured to include an area dividing module 206b for generating "" and a selection data display module 206c.

  The window generation module 206a generates a display area referred to as, for example, a multi-window system window or a main display screen on the display screen, assigns relative position coordinates in the window, and generates a frame (divided area). Make it possible. The area dividing module 206b divides the original frame (second divided area) defined in the window in accordance with data selection, scrolling, page break processing, etc., and executes a process for generating a divided frame. In addition, the selection data display module 206c performs processing for selecting a data set to be displayed by being assigned to the generated divided frame and assigning it to the divided frame.

  Further, the display area controller 206 manages the selection table 230. The selection table 230 can be configured using, for example, a buffer memory composed of a RAM or the like, a window buffer, etc., and registers the data identification value of the selected data for each divided area, that is, for each frame. It is possible to do. The selection table 230 will be described in detail later.

  As long as the application programs 210, 212, and 214 are programmed in accordance with the context of the programming language module 204, the type of processing is not particularly limited, but in this embodiment, for example, the browser application 210, the document management application 212, A word processor application 214 may be mentioned. In addition, for example, an image processing application, a graphic application, and the like can be appropriately implemented.

  The browser application 210 can be implemented by using, for example, Internet Explorer (trademark), Netscape Navigator (trademark), Mozilla, Opera, etc., and a structured document transmitted from a web server by an HTML parser, an XML parser, or the like. Is displayed on the window based on the structured document. Note that the browser application 210 is capable of processing, for example, JAVA (registered trademark) Script, JAVA (registered trademark) Applet, and the like, and can dynamically change the web page in response to a command from the user. It is preferable that

  In addition, the document management application 212 executes editing and searching of document data and image data stored in the information processing apparatus. The document management application 212 can execute the processing by accessing data managed by the document management application 212 or a database of a server connected via a network. The word processor application creates document data and registers it in a hard disk device or an externally connected server database.

  Input / output to each application program is performed via the input / output I / O 216. Each application program is VGA, USB, IEEE802. Data is transmitted / received to / from the display 218, the keyboard 220, and the mouse 222 using X or the like to execute data input / output. Each application program is connected to the network 226 via the network I / O 224 using the TCP / IP protocol, etc., connected to a LAN (local area network), the Internet, etc. Data is sent to and received from the server.

  In addition, each function module performs inter-process communication by signal, socket communication, and the like via the bus 228, and realizes each function module for configuring the GUI system 100 in cooperation with each other.

  FIG. 3 shows an embodiment of a data display window 300 displayed by the GUI system 100 of the present embodiment. The data display window 300 displays data managed by the document management application 212, for example. The data display window 300 shown in FIG. 3 is a window method or frame method that is prepared by the display area controller 206 corresponding to the programming language module 204 when the user activates the data selection utility of the application. , A window class, a frame class, or a JAVA (registered trademark) Window object, a frame object, and the like, and can be displayed on a display.

  In the present embodiment, the data display window 300 functions as a notation area. In the data display window 300, a plurality of display frames 302 and 306 function as divided areas. In the display frame 302, data managed by the application is displayed as a tree structure 304 corresponding to the hierarchical structure of the data. In addition, the display frame 302 includes a scroll bar 308, which moves the data to be displayed on the display frame 302 in response to an operation in which the user moves the scroll bar 308 up and down. Data is visually displayed in the display frame 302. Further, data that cannot be displayed on the display frame 302 as a result of the scroll operation is made invisible in the display frame 302. For example, in the embodiment shown in FIG. 3, up to the folder 10 is further created in the folder 1, but only the folder 8 is displayed in the display frame 302 in the scroll state of the display frame 302.

  In the present embodiment, the display frame 306 functions as a second divided region, and a list of files included in the folder 2 selected in the display frame 302 is displayed. Also for the file displayed in the display frame 306, by scrolling the scroll bar 310, the user moves the scroll bar 310 up and down until the target file is visually displayed in the display frame 306. Is visually displayed in the display frame 306. Although up to 14 files are stored in the folder 2, in the embodiment shown in FIG. 3, files other than the number defined by the size in the display frame 306 and the display size for displaying one file are stored. Is hidden.

  In the data display window 300 shown in FIG. 3, for example, when the user desires to display the folder 10, the user moves the scroll bar 308 downward. In the conventional GUI system, when the scroll process is performed to display the folder 10 in a visible manner, the currently selected folder 2 becomes invisible due to the size of the display frame 302. In the case of the conventional example described above, for example, when the user wants to move a file in the folder 10 to the folder 2, the user needs to operate the scroll bar 308 again to visually display the folder 2. Further, when moving a plurality of files in the folder 10 or when it is desired to modify the tree structure to a child folder of the folder 2, the folder 10 and the folder 2 cannot be displayed together. When the number of folders and files is small, it can be dealt with by correcting the frame size. However, as the number of data increases, resizing of the display frame cannot cope, and regardless of the number of data, the selected data is displayed in the data display window 300 separately from the scroll state. Confirmation of selected data, file transfer / copy, data structure modification, etc. are facilitated.

  The GUI system 100 according to the present embodiment displays a different display frame to display the selected data, and executes processing for displaying the selected data in a different display frame, thereby improving the efficiency of data editing. To do. Specifically, on the data display window 300, the user selects data by an operation such as single click or right click while the mouse icon 312 is superimposed on the folder 2. When the event handler 208 detects the data selection, the event handler 208 notifies the display area controller 206 and instructs the rearrangement of the display frame. Although various forms of display frame rearrangement can be assumed, the most direct rearrangement is performed by replacing the display frame 302 of FIG. 3 with the first display frame 402 and the first display frame 402, as in the data display window 400 shown in FIG. This is an embodiment in which two display frames 404 are divided and rearranged.

In the embodiment described with reference to FIG. 4, the GUI system 100 according to the present embodiment calls the resizing means in response to the folder 2 selection event, and executes the following processing. Display frame 302 on the window _{coordinates, p1 (x 1, y 1} ), p2 (x 2, y 2), p3 (x 1, y 3), the coordinates indicated by p4 _(x 2, _{y 4)} Has been generated. When the event handler 208 detects data selection, the display area controller 206 internally divides the y direction of the display frame 302 by a default value and generates a new minute point coordinate p5 (x ₁ , y ₅ ). Here, y ₅ = (y ₃ −y ₁ ) / m (m is an internal division ratio given on the upper side of the frame, and given as a positive real number). For example, when y ₃ = 300, y ₁ = 0, and internal ratio 10 are given on the window coordinates, the minute point coordinate p5 is generated as (x ₁ , 30). In the embodiment to be described, it is assumed that the upper left corner of the window coordinates gives (0, 0).

After that, the display area controller 206 generates the minute point coordinates of the corresponding second point p6 as (x ₂ , y ₅ ), and generates the second display frame 404 in the range of p1, p2, p5, and p6. . At the same time, the display area controller 206 modifies the first display frame 402 so that the end points have p5, p6, p3, and p4. Further, the selected data is displayed in the newly generated second display frame 404 in a visible manner, and in the first display frame 402, the folder 2 as the selected data is displayed in an invisible manner, thereby preventing duplicate display. This eliminates wasted display space.

  In the embodiment shown in FIG. 4, the display area controller 206 does not execute any processing other than display frame resizing. Therefore, the display frame controller 206 displays the first display as shown in FIG. The frame 402 and the second display frame 404 are displayed continuously. The newly generated second display frame 404 has no scroll bar, and the resized first display frame 402 has the scroll bar 406 as before. Is kept.

  For this reason, the user can separate the first display frame 402 from the scroll state in the first display frame 402 even when the scroll bar 406 is moved up and down to display data such as folders continuously. The selected data can be identified. The display frame 408 displays a file stored in the folder 2 that is the selected data, so that the contents of the data selected by the user can be recognized.

  A case where a plurality of data is selected in the embodiment shown in FIGS. 3 and 4 will be described. The event handler 206 manages the selection table 230 for registering the data identification value of the selected data. When a data selection event is detected by the user, the event handler 206 stores data identification values, for example, folder names, etc. in descending order in the selection table 230. To do. The selection table 230 can be implemented as a plurality of tables generated corresponding to each display frame, or a single table in which fields can be assigned so as to correspond to the display frame displayed at that time. Can also be implemented. The selection table 230 preferably corresponds to a notification from the event handler 208 that registers the selected data identification value, and sequentially adds and registers it corresponding to the selection history.

  On the other hand, the display area controller 206 generates the second display frame 404 by area division so that the second display frame 404 shares the outline of the display frame before the division. For this reason, the user can access data without a sense of incongruity with the display content of the display frame before division. After the second display frame 404 is generated, a display list in which the latest data identification value entered in the selection table 230 is newly generated, specifically, the visible display data of the second display frame 404 is registered. Register additional. The display list is generated corresponding to each target frame for region division, and selection data of other display frames is not displayed in the divided frames that are completely unrelated.

  Further, the data identification value entered in the display list is held as a candidate to be displayed in the second display frame 404. In addition to a field for registering a data identification value, a control field for registering a duplicate display avoidance flag or a duplicate display avoidance identification value is generated in the entry field of the display list. In addition to data selection, the value of this control field is updated depending on the scroll state / page break state after data selection. For example, when the selected data is displayed in the first display frame 402 in response to the scroll state of the first display frame 402 after the data is selected, the display area controller 206 includes the selection table 230, the display list, and The data currently displayed in the first display frame 402 is searched, and the result set of the set product of (selection table 230∩data currently displayed in the first display frame 402) regarding the selected data is selected. Even if is canceled or selected, it is in the display state in the first display frame.

  When the display area controller 206 acquires the data identification value included in the result set, the control flag or the control value that instructs “non-display” in the control field of the record in the display list corresponding to the data identification value included in the result set. Set. After that, the display area controller 206 controls the display of the selected data in the second display frame 404 with reference to the value of the control field, so that the overlapping display in the first display frame 402 and the second display frame 404 is performed. Eliminate. By the above-described overlapping display avoidance process, the data that is to be visually displayed in the first display frame 402 can be reversibly displayed / hidden in the second display frame 404 without changing the selection order. Is possible.

  Note that when the duplicate display avoidance process is not implemented, the display list does not require a control field for duplicate avoidance control. Further, a data identification value field and a control field for avoiding duplicate display are configured for the selection table 230, and data to be displayed in the second display frame 404 is selected from the selection table 230. You can also. In the embodiment in which the control field for avoiding duplicate display is configured in the selection table 230, the data selection result by the user can be reversibly displayed / hidden including its sequence, and the table list This is preferable in that the number of references is reduced and the programming perspective is improved.

  Further, when adding / deleting an entry item of the display list, the display area controller 206 executes a resizing process for correcting the size of the second display frame 404 to a necessary minimum size, and displays the display in the first display frame 402. The effect on sex is minimized. Note that the term “resizing” includes not only enlargement / reduction of the second display frame 404 but also deletion, and at the same time, interlocking with the size of the first display frame corresponding to enlargement / reduction / deletion of the second display frame 404. This means processing accompanied with reduction / enlargement processing.

  The display area controller 206 monitors entry items in the display list. When there are no more entry items in the display list, the display area controller 206 deletes the generated second display frame 404 and executes resizing of the first display frame. The original display frame 302 shown in FIG. 3 is restored. The entry item of the display list also functions as a clipboard for the user to perform a specific operation, and is displayed in the second display frame 404 when the user performs another action on the selected data. The purpose of letting it ends.

  For this reason, when the display area controller 206 is notified by the event handler 208 that another action has been performed on the selected data, the display area controller 206 performs a process of deleting the entry item of the corresponding data in the display list. Execute. When there are no more entry items in the display list, the display area controller 206 executes processing for deleting the second display frame 404 and restoring the display frame 302.

  When data selection is performed by the browser application 210 via the network, when the event handler 208 detects the data selection, a child frame that separates and displays the selected data is generated as the second display frame 404 and selected. It is also possible to perform a process of inheriting the data identification value thus obtained as a data value to be displayed on the second display frame 404. In this case, the display area controller 206 can also acquire the data selected by referring to the selection table 230, or display it visually using a log described in the browser log instead of the selection table 230. The data identification value to be visibly displayed.

  FIG. 5 shows a flowchart of an embodiment of a GUI generation process executed by the GUI system 100 of the present embodiment. The process shown in FIG. 5 starts from step S500, and in step S501, data such as a file and a folder is visually displayed in response to scrolling of the first display frame. In step S502, it is determined whether the data displayed in the first display frame has been newly selected. If no data is selected (no), the process returns to step S501 and scrolling is repeated until data is selected.

  If new data is selected in step S502 (yes), the data identification value of the selected data is stored in the selection table 230. At this time, registration in the selection table 230 can be performed in the order displayed in the first display frame or in the order of selection. When displaying in the second display frame in the order in which they are displayed in the first display frame, for example in the case of collective selection, the identification of data selection is improved, and when displaying in the selection order, the target data is displayed in the order of selection. Accordingly, it is easy to confirm that the selection has been made. Moreover, these registration methods can be implemented in combination as appropriate according to a specific application.

  In step S503, it is determined whether or not the second display frame 404 already exists. Whether the second display frame 404 already exists can be determined using various methods. For example, the display area controller 206 corresponds to the frame identification value for each existing frame at the time of frame creation. To set the frame generation flag. When determining whether the second display frame 404 exists for the display frame to be processed, whether the frame generation flag is already set in relation to the target frame for generating the second display frame 404, Judgment can be made based on whether it is not set. In addition to the above, any method can be used as long as the frame can be identified and the generation of the second display frame 404 can be determined.

  If the second display frame 404 does not exist (no), the second display frame is generated with the default setting (minimum size) in step S504. On the other hand, if the second display frame 404 already exists (yes), the number of data to be displayed so as to optimize the size of the second display frame 404 in response to the number of data to be displayed in step S506. The image is resized so that it increases when it increases and decreases when it decreases. The resizing process can be performed in the same manner as the process of FIG. 4, and the y coordinates of p5 and p6 are increased and decreased by a set increment value to obtain corrected values, and the first display frame and the second display frame 404 are displayed. Can be executed by associating and resizing. Note that the maximum size of the second display frame 404 can be set for the resizing process, and an area for data search and data selection processing is provided so that the second display frame 404 is not enlarged beyond the maximum size. It may be ensured at all times.

  If it is determined in step S503 that the second display frame 404 exists (yes), the process proceeds to step S505, and it is determined whether or not the size of the second display frame 404 is optimal for displaying data. For example, when the second display frame 404 is generated with sufficient margin in advance and is optimal (yes), the process is branched to step S507. If it is determined in step S505 that the second display frame 404 is not the optimum size (no), the second display frame is resized in accordance with the data to be displayed in step S506, and the process branches to step S507. .

  In step S507, the data identification value acquired from the selection table 230 is added to the generated or resized second display frame 404, the newly added data is displayed, and the display items are rearranged. Thereafter, the process returns to step S501, and a process corresponding to the selection of new data is executed. In another embodiment, after the folder 2 is selected and displayed on the second display frame 404, the folder 2 is deleted from the display data of the first display frame 402, thereby avoiding duplicate display and window display efficiency. Can also be improved.

  Note that when data exceeding the maximum size is selected, that is, when the data selection is notified from the event handler 208 after the GUI system 100 determines that the maximum size has been reached, the data selected in the order from the top selected data is not displayed. It can also be displayed. In a more preferred embodiment, when data exceeds the maximum size set in the second display frame, the display area controller 206 erases the second display frame and displays it in the second display frame. A second data display window, a pop-up window, a list box, or the like for displaying power data can be generated instead of the second display frame.

  FIG. 6 shows a second embodiment of the GUI generation processing of the GUI system 100. In the embodiment shown in FIG. 6, the data selection event is not triggered by the generation of the second display frame 404 or the movement to the second display frame 404. The scroll state is monitored, and the selected display data is deleted from the display data of the first display frame 402 by the first display frame 402 by the user, that is, the process is set to hide in the first display frame 402. As an example, the generation of the second display frame 404 or the movement to the second display frame 404 is executed.

  In the second embodiment, a display frame 602 and a display frame 608 are formed in the display window 600 as shown in FIG. In the display frame 602, the hierarchical structure of the data to be processed is displayed as a tree structure. Further, in the display frame 602, the data identification value indicating the folder 2 is highlighted in correspondence with the selection of the folder 2. The display frame 608 displays a list of files registered in the selected folder 2.

  FIG. 6B shows an embodiment in which the user operates the scroll bar 606 downward to display a subsequent folder in the display frame 602. In the data display window 610 shown in FIG. 6B, the scroll bar 616 is moved to the bottom, and the last folder 9 is displayed accordingly. Correspondingly, the selected folder 2 is not displayed. In response to this, the GUI system 100 displays the display frame 602 as the first display frame 612 and the second display frame 614 corresponding to the processing in which the folder 2 is not displayed in the display frame 602 of FIG. Divide into At this time, in the second display frame 614, the folder 2 that is selected in the first display frame 612 but is hidden in response to the change in the scroll state is the same processing as described in the first embodiment. Is displayed as the target data for visible display in the second display frame 404. Note that the second display frame 618 in FIG. 6B displays a file that is the content of the selected folder 2. Note that the display content of the second display frame 618 can be updated so that the content of the folder selected last is displayed.

  FIG. 7 is a flowchart of the GUI generation process according to the second embodiment. The process shown in FIG. 7 starts from step S700. In step S701, selection of data in the first display frame is detected, and a data identification value of the selected data is stored in the selection table 230. At this time, registration in the selection table 230 can be appropriately selected according to a specific application as described with reference to FIG. In step S702, the first display frame 612 is scrolled to display data to be further selected.

  In step S703, it is determined whether or not non-display is performed in the first display frame 612 among already selected data.

  Note that the determination that the selected data is not displayed is made by scrolling the data displayed at the top or the bottom by scrolling in the y direction as in the embodiment shown in FIG. If so, the display area controller 206 determines based on whether the upper limit coordinate or the lower limit coordinate in the y direction of the data display exceeds the upper limit value or the lower limit value in the y coordinate direction of the window coordinate of the first display frame 612. Can do. For example, as a result of the scroll processing, regarding the y coordinate in the window coordinate system, when the upper limit coordinate of data display is PU and the upper limit value of the y coordinate of the first display frame is FU, and PU> FU, the downward direction is reached. Corresponding to the scrolling, the uppermost data is not acquired as a data list to be displayed in the first display frame, thereby making the data invisible in the first display frame. In the case of scrolling in the upward direction, the lower limit coordinate of the data display is set to PL, the upper limit value of the y coordinate of the first display frame is set to FL, and the data to be judged is displayed when PL <FL.・ Hide can be controlled.

  If the data selected in step S703 is not hidden (no), the process branches to step S701 to detect additional data selection. On the other hand, if it is determined that the selected data is not displayed in the first display frame (yes), it is determined in step S704 whether the second display frame already exists. The determination in step S704 can be executed by the same process as described in step S503 in FIG. If it is determined in step S704 that the second display frame does not exist (no), the second display frame is generated using the process described in FIG. 5 in step S706, and the selection table is selected in step S708. The newly selected data identification value is acquired from 230, the data is displayed in the second display frame, and the display data is rearranged in the second display frame.

  On the other hand, if it is determined in step S704 that the second display frame is present (yes), it is determined whether the second display frame is of a size sufficient for displaying the newly selected data. If it is determined in step S705 that the size of the second display frame is not optimal (no), the second display frame is resized in the range from the set maximum value to the erasure in step S707. On the other hand, if it is determined in step S705 that the second display frame has a sufficient size (yes), the process branches to step S708 to acquire the newly selected data identification value from the selection table 230, and the second Display the data in the display frame and rearrange it.

  In step S709, the data displayed in the second display frame is deleted from the first display frame in response to the scroll operation, the process is branched to step S701, and the process is repeated until the data selection process is completed.

  The GUI generation process described with reference to FIG. 7 has been described using the embodiment in which the second display frame is created in response to the scroll operation in the first display frame. In the third embodiment of the GUI generation process, a page turning / page returning process (hereinafter referred to as a page break process) of the first display frame is employed instead of the scroll process. For example, when coding in JAVA (registered trademark), the scroll processing is displayed in the frame by using the Scrollbar class and setting the display direction, initial value, page size, minimum value, and maximum value. Data display can be implemented by describing a data selection process to be displayed in the adjustmentValueChanged () method.

  Further, the page processing can be implemented by creating a page turning button by using the Button class and describing processing for displaying the number of data that can be represented in the first display frame as the actionPerformed () method. it can. In this case, a page return button can be set together with a page turning button. As described above, the data display process in the first display frame can be appropriately set according to a specific application or purpose. However, when the data is not displayed, the second display frame is created and scrolled. Alternatively, the process of displaying the selected data separately from the page change can be performed in the same manner.

A display field 806 displays a list of files related to the data currently selected by the user.

  Here, it is assumed that the user edits data and performs a process of changing the hierarchy of data specified by the folder 2 to a child node having the folder 10 as a parent node, not the parent node. In this case, in this embodiment, as illustrated in FIG. 8B, the user performs a scroll operation on the first display frame 802 to display the folder 10. In the display state shown in FIG. 8B, conventionally, data from folder 1 to folder 6 is not displayed. However, by implementing the GUI function block of this embodiment in the file manager, the data selected by the user is kept visible in the second display frame separately from the scrolling and page turning processing in the frame. Is shown. The user uses the GUI display shown in FIG. 8B to change the folder 2 displayed in the second display frame 814 of the data display window 810 to the folder 10 displayed in the first display frame 812. It can be easily dragged and dropped.

  FIG. 8C shows that the folder 2 is edited as a child node of the folder 10 in the first display frame 822 in response to the user operation of FIG. Correspondingly, the selection of the folder 2 is canceled in response to the execution of another user operation corresponding to the selection and the achievement of the user selection purpose. When the selection of data is canceled, the data whose selection has been canceled is deleted from the display data list in the second display frame, and is not displayed in the second display frame. In the case of the embodiment shown in FIG. 8C, the selected data is only the folder 2, and when the data of the folder 2 is deleted from the display list, the display list to be displayed in the second display frame is null. It becomes.
