Method and system for realizing window drawing based on native window on Web operating system

The invention discloses a method and a system for realizing window drawing based on a native window on a Web operating system, and the system comprises a graphic data production module which runs on a Web application, and a native window compatible module and a synthesis module which run on a Web engine, the native window compatible module creates a native window compatible interface instance under the management of the Web engine and returns the native window compatible interface instance to the graphic data production module, a graphic buffer area queue module is realized in the native window compatible interface instance, and the graphic data production module pushes graphic display content to a graphic buffer area in the corresponding graphic buffer area queue module. And extracting by a synthesis module to finish drawing of the window. According to the method, the capability of accessing the native window can be provided for the Web application on the Web operating system, the Web application can access
