FIG. 2 is a diagram of a document window according to the present invention.
Detailed Description
The participators applied by the method of the invention are divided into an initiator and a responder according to roles. And multiple types of file opening are supported, and multiple files are simultaneously opened. The application scenario is that a plurality of clients and a server are used, wherein the plurality of clients communicate through the server and adopt a C/S structure and a TCP protocol for transmission. Each client has the functions of initiating and responding to the on-line multi-file multi-terminal synchronization. The interaction flow of the online file is shown in fig. 1.
The client adopts an MVC architecture and comprises a display layer, a control layer and a data layer:
1. the presentation layer refers to an operation meeting of a user, and comprises a file base view and a file content view, as shown in fig. 2;
2. the control layer is a core service logic and is responsible for file display strategies, data coding and decoding and data receiving and transmitting under different states;
3. the data layer is responsible for the definition of various data and data management.
The opener selects the file to be opened, obtains the type and the required data of the file to be opened, constructs the Widget message data for encoding, and stores the file in a List; and when the same file is opened again, judging whether the file to be opened exists in the List or not, if so, not processing, and if not, sending the encoded Widget message to the initiator and the server. The server may distribute to other clients that are online. The Widget message comprises window information and file exclusive information; the window information comprises the pixel position of the file in the file window and the size of the file window; the file specific information includes: the storage path of the file on the server and the current display content.
The audio and video file is used for playing audio and video files, and the file exclusive information in the Widget message is as follows: the playing Url, the current playing position, the total time length, the playing state and the playing speed are used for synchronizing the contents of the audio and video files;
the PDF file is used for displaying PDF, and the file exclusive information in the Widget message is as follows: url to be displayed, the current page number, the read position, the note information and the code are used for synchronizing the content of the PDF file and then sent to a server;
the exclusive information of the file in the WORD file and the Widget message is as follows: url to be presented, the current page number, the read position, is used for synchronization of the WORD file contents.
The text file is used for displaying text files such as TXT, JAVA and the like, and the exclusive information of the files in the Widget message is as follows: url of the open file, and the synchronization state of the text file, which are used for synchronizing the content of the text file.
The PPT file is used for displaying the PPT file, and the exclusive information of the file in the Widget message is as follows: url of PPT, the current page number, and the read position are used for PPT file content synchronization.
The image file is used for displaying an image, and the file exclusive information in the Widget message is as follows: url, width and height of the picture, and angle selection for picture content synchronization.
The user-defined file is used for displaying the picture and sharing the screen file, and the user-defined content is realized through other interfaces because the user-defined data Widget message is not easy to expand; for example, when a web page is opened, the specific information is: the webpage address, the webpage title and the authority, wherein the authority is used for indicating whether the webpage can be operated by a viewer. For another example, the initiator may share a part of the desktop, and the widget message does not satisfy the requirement, and generally receives or sends the widget message through another command to share the desktop information.
And the responder receives and analyzes the Widget message forwarded by the server and displays the Widget message, and firstly judges whether the file is displayed locally or not according to the FileId List. If not, firstly analyzing window information and file types in the Widget message, locally drawing a window for displaying files, and correspondingly displaying different file types. If the file exists locally, the view layer is notified to update the file. The above process is repeated every time a widget message is received.
The initiator and the responder can adjust the size of a file window through a mouse or a finger (mobile phone), calculate the display position of the current file, modify the Widget message and send the Widget message to the server; including operations such as double-click max, double-click recovery, file movement, file size scaling, etc., as shown in fig. 2, a file window diagram is shown.
And the responder analyzes the position information in the Widget message by the control layer, compares the position information with the local position information, updates the display position of the file window if the position information is different from the local position information, ignores the exclusive information of the file, and judges the exclusive information of the file if the position information is the same as the local position information.
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.
