摘要： The techniques disclosed herein synchronize focus between two operating systems that run concurrently. A proxy application running on a primary operating system (OS) presents a guest application running in a secondary OS as if it was native to the primary OS. User interface events received by the proxy application are forwarded to the corresponding guest application. Each OS independently identifies which application currently has focus. When the primary OS is focused on a proxy application, focus is synchronized by setting and maintaining the focus of the secondary OS to the corresponding guest application. When the primary OS is not focused on a proxy application, the focus of the secondary OS is set to a stub placeholder application. Keeping focus synchronized prevents user interface events received by the proxy application from being forwarded to the wrong application on the secondary OS.
