A means for creating a page, a means for inserting a page break at an appropriate position according to the sorted attribute, a means for creating a tab on the page and automatically creating a name, and a means for detecting a change in the window size. It is characterized by the points provided.
The display method according to the present invention includes a step of acquiring a file attribute from a file system, a step of acquiring a display window size, a step of rearranging according to the attribute of the file, The process of creating a page, the process of inserting a page break position at an appropriate position according to the sorted attribute, the process of creating a tab on the page and automatically creating a name, and the process of detecting a window size change It has the feature in having.
The computer program according to the present invention includes a process for obtaining a file attribute from a file system, a process for obtaining a display window size, a process for rearranging according to the attribute of the file, and a dynamic display according to a change in display area when displayed. Processing to create a page in the page, processing to insert the page break at the appropriate position according to the sorted attributes, processing to create a tab on the page and automatically create a name, and processing to detect a change in the window size It is characterized in that it is executed by a computer.
The computer-readable recording medium according to the present invention is characterized in that the computer program of the present invention is recorded.

  According to the present invention, the file display is set for each page and a tab is added, so that the user can directly move to the page on which the target file is described. Problems such as fatigue can be solved. In addition, since pages and tabs are dynamically created even if the window size is changed, it is possible to display according to the usage situation.

  Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a schematic system configuration. Reference numeral 100 denotes an OS (Operation System) having a file system. Reference numeral 101 denotes a selection unit having a selection function such as a mouse or a keyboard. Reference numeral 102 denotes a display unit such as a cathode ray tube display that displays a file structure. Reference numeral 103 denotes a file viewer that forms the core of the display function.

  FIG. 2 shows an internal configuration example of the display device. An OS interface unit 200 interfaces with the OS, and acquires window information and file viewer information from the OS. A page creation unit 201 determines a suitable page break position from the window size. A tab creation unit 202 creates a tab. A display data creation unit 203 creates screen display data from the page data acquired from the page creation unit 201 and the tab data acquired from the tab creation unit 202. A main control unit 204 controls each unit, and manages main control that is data transfer of each control unit such as passing data acquired by the OS interface unit 200 to the page creation unit 201.

  FIG. 3 shows an image on the screen. An outer frame 300 is a window showing a file viewer, and the window size can be changed by dragging the window size changing unit 301 with a mouse. A frame 302 is a folder viewer (Folder Viewer) showing a folder structure. A frame 303 is a file viewer that displays the internal structure of the folder designated by the folder viewer 302. A tab 304 is a tab of a page that is created when all contents cannot be displayed in the window of the file viewer 303. By selecting the tab 304, the designated page can be displayed. By operating the previous page moving unit 305 with the mouse, the previous page is displayed. The next page is displayed by operating the next page moving unit 306 with a mouse.

  Next, the processing operation in the display device will be described with reference to the flowchart of FIG. In step S400, whether or not a folder is selected is constantly monitored, and if selection of a folder is detected, the process proceeds to step S401. In step S <b> 401, information on folders and files under the selected folder is acquired from the OS interface unit 200.

  In step S <b> 402, the size of the window that is the display space is acquired from the OS interface unit 200. In step S403, the acquired information is continued in the order of the folder names and sorted in the order of the file names. The sort function is in the order of names in this embodiment, but other sorts are possible by specifying a default or a user.

  In step S404, the page creation unit 201 creates a page from the display area. In consideration of adding tabs to page breaks, page breaks should be made at places where cuts are good. The page break process will be described later.

  In step S405, the tab creation unit 202 creates a tab for each page from the page created in step S404. The tab name generation method of this embodiment will be described later.

  In step S406, the display data creation unit 203 acquires the page data created by the page creation unit 201 and the tab data created by the tab creation unit, and creates final display data.

  In step S407, the display data created by the display data creation unit 203 is transferred to the display unit 102 for display.

  Step S408 is an event that occurs when the size of the window is changed. When this event occurs, the process proceeds to step S402 to acquire the window size.

  Here, page break processing will be described. The page creation unit 201 performs a page break by the following processing. The file information after the sorting process is acquired, and it is confirmed whether it fits on one page of the window size. If it fits, it is displayed as one page without a tab. If it does not fit, a page break position to enter one page is detected. The following method is used to detect whether there is an appropriate place to insert a tab in a line near the page break position of the number of displayable lines. A case will be described where the number of displayable lines is 50 and the page break insertion permission range is 80% or more. When the number of displayable lines × page break insertion permission range is performed, 50 lines × 80% = 40 lines, and page breaks may be inserted between 40 lines and 50 lines. The page creation unit 201 detects the most appropriate place between these lines. The page break insertion permission range is 80% as a default value, but can be changed by the user. If the state from the 40th line to the 50th line is the order shown in the page break insertion candidate diagram shown in FIG. 5, the leftmost character is different, so the page break between the 44th line and the 45th line. Is inserted. The page break insertion process for the second page starts from the 45th line, and the same operation as described above is repeated until the last page.

  Next, tab name generation processing will be described. The tab has various formats such as displaying the first file name and the last file name of the page, and displaying only the first file name. In this embodiment, the leftmost file with the page break is inserted in the first file of the page. The display is to the place where the characters are different. In the example of FIG. 5, “Kazu” is displayed and the tag 304 tab illustrated in FIG. 3 is represented. Since the display example of the window in FIG. 3 is not a 50-line display, only the tab name is used as a reference.
