Just connect with XOpenDisplay() . 只需与XOpenDisplay()连接XOpenDisplay() 。 The Display structure is just the information for your connection to the X server. Display结构只是您与X服务器连接的信息。
XGetInputFocus() will give you the client window with focus on the X server to which you are connected. XGetInputFocus()将为您提供客户端窗口，重点放在您连接到的X服务器上。
