Desktop end software pendant window management method and system

The invention provides a desktop end software pendant window management method and system, which are implemented on a main application and a sub-application. The method comprise the following steps of: running the main application to generate a main window; running the sub-applications in an external container to generate a plurality of pendant windows; performing display level configuration on the main window and the plurality of pendant windows; and through communication between the main application and the sub-application, realizing management of the pendant window. By adopting a sandbox isolation technology, the system has the advantages of being good in isolation performance and capable of conveniently integrating multiple different technology stacks, meanwhile, unified management isadopted for the display levels of all the pendant windows, pendant window interaction specifications are unified, and control switching between different components is more flexible and convenient. 本发明提供了一种桌面端软件挂件视窗管理方法和系统，在主
