Abstract: The present invention relates to the field of computers. Disclosed are an application program interface display method, device, terminal and readable storage medium. The method comprising: displaying a first window on the full screen and displaying a first application program interface in the first window; displaying a second window above the first window, and displaying a second application program interface in the second window; and always maintaining the first window in a focused state during switching between the first window and the second window. The above technical solution ensures that the application program interface displayed in the first window remains functional without losing the focused state, and the application program interface displayed in the second window remains to be displayed above the first window even in a non-focused state, thus facilitating operation.

Abstract: An apparatus for manufacturing a light guide film may comprise a feed roller, a receiving roller, a separating device, a hot press printing device and a recombining device. Firstly, the separating device may separate a protective layer from a substrate layer of the light guide film. Secondly, a surface of the substrate layer to be manufactured may be impressed with light guide dots by the hot press printing device, and the recombining device recombine the peeled protective layer to the substrate layer. And lastly, the finished light guide film is recycled by the receiving roller. The apparatus may have advantages such as high output and low cost, and it may manufacture a large dimensioned product.

Abstract: A method and a device for invoking a plug-in function are disclosed, which relate to the technical field of wed games. The method includes: detecting whether there exists a need to execute a function of a preset plug-in in an online game, and if there exists the need to execute the function of the preset plug-in in the online game, acquiring a type of a browser on which the online game is played; when the browser on which the online game is played is a non-IE browser, acquiring the preset plug-in and instantiating a refresh-free plug-in instance according to the preset plug-in; and invoking the refresh-free plug-in instance in the online game, and executing a function of the preset plug-in. Through the present invention, it is not required to refresh a webpage in an IE browser, and the function of the preset plug-in can be executed by instantiating the refresh-free plug-in instance, thereby improving the execution efficiency of the webpage.

Abstract: A method is provided for group communication data exchange. The method includes sending by a business client an identifier of a communication group corresponding to a user group including a first user to a voice service client, and establishing by the voice service client a long connection between the voice service client and a voice service system based on the identifier of the communication group. The method also includes adding by the voice service system the user to a communication group included in the voice service system, and performing by the voice service client data exchange with the voice service system over the long connection for group communication data generated by the communication group.

Abstract: A method for processing data is provided. In the method, the terminal device receives a blocking command to screen out a specified user identification. The terminal device sends a blocking request comprising the specified user identification to the server so that the server screens out at least one data packet comprising the specified user identification when sending data packets to the terminal device. Accordingly, the embodiment of the present disclosure also provides corresponding clients, servers and systems.

Abstract: Systems and methods are provided for data exchange in voice communication. For example, a first request message is sent to a server for playing background music in voice communication; an authorization granted by the server to play background music separately from the voice communication is received; and upon reception of a play instruction from a user, the background music is played and an identifier of the background music is sent to the server. The server broadcasts the background music to one or more clients based on at least information associated with the identifier of the background music.
