in the application, the second file number is the number of files capable of being displayed in the browsing area; for example, in a possible embodiment, the browsing area can present 10 files, and correspondingly, the second file number is equal to 10.

S133, if the number of the first files is less than or equal to the number of the second files, controlling the browsing area to display all the files;

s134, if the number of the first files is larger than the number of the second files, controlling the browsing area to display the files in the first set, and controlling the preview area to display the files in the second set.

The first set comprises at least one browsing file, the browsing files are files with sequence numbers from 1 to N, N is the number of second files, the second set comprises at least one preview file, and the preview file is a file adjacent to the browsing file.

In this application, the file adjacent to the browsing file may include a file with a serial number before the serial number of the browsing file, and may also include a file with a serial number after the serial number of the browsing file, and specifically, the number of the preview files is determined by the files that can be accommodated in the preview area. For example, in a possible embodiment, the file manager includes 20 files, which are respectively: file 1, file 2 … … file 20, if 5 files can be displayed by browsing files, N is equal to 5, and when the file manager is started for the first time, the first set generated by the controller includes file 1, file 2 … … file, 5. The preview area can show 5 files, and the files contained in the second set are file 6, file 7 … … file 10.

In the application, the number of the display files in the browsing area and the number of the display files in the preview area may be different. In some feasible embodiments, the number of browsing area presentation files and the number of preview area presentation files may be the same in order to reduce the computational load of the processor.

The following describes the display effect of browsing and previewing files with reference to specific drawings.

FIG. 14 is a schematic view of a spatial field of view provided according to one possible embodiment. In this embodiment, the file manager includes 4 files (the first number of files), the browsing files can display 10 files (the second number of files), and the first number of files is smaller than the second number of files, so that the controller only draws the browsing area and displays all 4 files in the browsing area, and the spatial view at this time can refer to fig. 14.

FIG. 15 is a schematic view of a spatial field of view provided according to one possible embodiment. In this embodiment, the file manager includes 14 files (the first number of files), the browsing files may include 10 files (the second number of files), and the first number of files is greater than the second number of files, so that the controller only draws the browsing area and the preview area, and displays 10 browsing files in the browsing area and 4 preview files in the preview area, where the spatial view area may refer to fig. 15.

To achieve the above-mentioned effects, this embodiment further illustrates a method for generating the first set, specifically referring to fig. 16, where fig. 16 is a flowchart illustrating a method for generating the first set according to a possible embodiment, and on the basis of the display device illustrated in the foregoing embodiment, the controller is further configured to: in response to a user click on a preview document, the controller is further configured to:

s161, reading a first page code value C1, wherein the first page code value is a page number corresponding to the clicked preview file;

in the technical solution applicable to this embodiment, the number of files that can be displayed in the preview area is equal to the number of files that can be displayed in the browsing area. Therefore, when the file manager is opened, all files can be divided into N groups according to the number of the files which can be displayed in the preview area, and the page number value corresponding to each group of files is already a fixed value. For example, in a feasible embodiment, the document manager includes 25 documents, and the number of the documents that can be displayed in the preview area is 5, in this case, the controller may divide the 25 documents into 5 groups, where documents 1 to 5 are a first group of documents, and the page value of the first group of documents is 1; files 6-10 are a second set of files, the second set of files having a page value of 2; files 11-15 are a third set of files having a page value of 3; files 16 to 20 are fourth group files, and the page value of the fourth group files is 4; the files 21 to 25 are files of the fifth group, and the page value of the fifth group is 5.

S162 judging whether the first page code value is larger than 1;

s163 if the first page value is greater than 1, controlling a first sub-preview region of the display to show a first sub-set, the first sub-set comprising files with sequence numbers { (C1-2) × N +1, (C1-1) × N }, the first sub-preview region being located at one side of the browse region.

For example, in a feasible embodiment, the document manager includes 8 documents, the number of documents that can be displayed in the preview area is 4, the first page value is 2, and the first subset includes { document 1 to document 4}, in which case the spatial view can refer to fig. 17.

If the first page number is equal to 1, S164 controls the browsing area to display a first set without displaying a first sub-preview area

For example, in a possible embodiment where the document manager includes 4 documents, the preview area may display 4 documents, and the first page value is 1, the space view may refer to fig. 18.

With continued reference to fig. 16, the controller is further configured to execute step S165 of determining whether the first page code value is less than a total page code value;

the controller is further configured to perform step S166 of controlling the display not to display the second sub preview area if the first page code value is equal to the total page code value.

Specifically, the spatial view display effect can be seen in fig. 18.

In the application, the second sub-preview area is located on the other side, and the second sub-preview area and the first sub-preview area are located on two different sides of the browsing area.

In the present application, the different sides may be opposite sides, for example, a left side and a right side. Or may be adjacent sides, such as the top and right sides.

With continued reference to fig. 16, if the first page code value is less than the total number of pages, the controller is further configured to execute step S166 to generate a second subset, where the second subset includes files with sequence numbers { C1 × N +1, a termination sequence number }, where the termination sequence number is determined by the first page code value and the first number;

for example, in one possible embodiment, the document manager includes 12 documents, the number of documents in the preview area is 4, the first page value is 2, the first subset includes { document 1 through document 4}, the first subset includes { document 5 through document 8}, and the second subset includes { document 9 through document 12}, and then the spatial view can refer to fig. 19.

The controller executes step S167 to control a second sub-preview area of the display to show the files contained in the second sub-collection.

In this embodiment, a method for generating the second subset is shown, and specifically, referring to fig. 20, the controller is further configured to:

s201 determines whether C1 x (N + 1) is greater than or equal to a first number;

s202 if C1 x (N + 1) is greater than or equal to the first number, the stop sequence number is equal to C1 x (N + 1).

S203 if C1 x (N + 1) is less than the first number, the stop sequence number is equal to the first number;

for example, in a feasible embodiment, the file manager includes 23 files, the number of the files that can be displayed in the preview area is 4, the first page value is 5, C1 x (N + 1) =4 x (5+1) is greater than 23, the first subset includes { file 13 to file 15}, the first set includes { file 16 to file 20}, and the second subset includes { file 21 to file 23}, where the spatial view can refer to fig. 21.

For example, in a possible embodiment, the document manager includes 25 documents, the number of documents that can be displayed in the preview area is 4, the first page number is 5, C1 x (N + 1) =4 x (5+1) is less than 25, the first subset includes { document 13 to document 15}, the first set includes { document 16 to document 20}, and the second subset includes { document 21 to document 24}, where the space view can refer to fig. 22.
