doClose

从接口复制的说明: CefLifeSpanHandler

Called when a browser has received a request to close. If CEF created an OS window for the browser returning false will send an OS close notification to the browser window's top-level owner (e.g. WM_CLOSE on Windows, performClose: on OS-X and "delete_event" on Linux). If no OS window exists (window rendering disabled) returning false will cause the browser object to be destroyed immediately. Return true if the browser is parented to another window and that other window needs to receive close notification via some non-standard technique.
(在浏览器收到关闭请求时调用。 如果CEF为浏览器创建了一个OS窗口，则返回false将向浏览器窗口的顶级所有者发送操作系统关闭通知（例如Windows上的WM_CLOSE，OS-X上的performClose：和Linux上的“delete_event”）。 如果不存在OS窗口（禁用窗口渲染），则返回false将导致浏览器对象立即被销毁。 如果浏览器是另一个窗口的父级，并且其他窗口需要通过某种非标准技术接收关闭通知，则返回true)
