Dynamic generation apparatus and method for application program interface

Abstract

The invention provides a device for dynamically generating an application program interface. The device comprises an external interface, an interface description interpreter, an element manager, a layout manager and an element wrapper. The external interface is used for receiving an interface description file and outputting to the interface description interpreter; the interface description interpreter is used for analyzing the interface description file according to the description definition of preset interface elements and obtaining the attribute information and layout information of the interface elements; the element manager is used for calling interface element codes wrapped in the element wrapper according to the attribute information received from the interface description interpreter, and creating and arranging the interface elements; the layout manager is used for arranging the interface elements created by the element manager according to the layout information received from the interface description interpreter and generating the application program interface; the element wrapper is used for wrapping the interface element codes. The device has the advantages of dynamically generating the application program interface, greatly reducing the coupling degree between logical codes and interface codes, and enabling the application program interface to be more flexible. At the same time, the invention further provides a method for dynamically generating the application program interface.

Description

technical field [0001] The invention relates to the field of interface technology, in particular to a device and method for dynamically generating an application program interface. Background technique [0002] At present, the vast majority of applications use the graphical user interface as the application program interface. With the enrichment of application program functions, the design of the program interface becomes more and more complicated. The general graphics library generated for the application program interface, for example, GTK (GIMP Toolkit) is one of the most widely used ones. GTK provides a wealth of interface functions to construct application program interface elements. Application developers can add , create and layout the required interface elements through GTK primitives, so as to construct a vivid graphical application interface. In addition, using the GTK-based interface generation tool can generate interface code more conveniently, thereby saving th...

[0010] Although the interface generation tool can simplify the writing of interface codes, and at the same time use the interface description as a bridge between logic codes and interface codes, it also achieves the separation of interface codes and logic codes to a certain extent, reducing the gap between interface codes and logic codes. The degree of mutual influence between them, that is, the degree of coupling, but because the C language code of the interface part generated by the interface generation tool needs to be compiled and connected with the logic code of the application program, in fact, the code of the final application program still includes the code of the interface part. There is still a certain degree of coupling. In this case, when the interface is adjusted, even small adjustments such as interface element properties, it is necessary to modify the application, repeat the multiple steps of the above interface generation, and finally reconnect with the logic of the application. Code compilation and connection, the flexibility and scalability of the interface design will be greatly limited, which is very inconvenient for the later maintenance and update of the application program interface

[0011] In addition, the existing interface generation tools provide complex interfaces, and many interfaces need to be used in the logic code of the application to interact with interface elements, which increases the complexity of the application and increases the interface development effort to a certain extent. difficulty and complexity
