参数:

browser - The browser generating the event. (-浏览器生成事件。)

onSetFocus

public boolean onSetFocus(CefBrowser browser,
                          CefFocusHandler.FocusSource source)

从接口复制的说明: CefFocusHandler

Called when the browser component is about to loose focus. For instance, if focus was on the last HTML element and the user pressed the TAB key. (当浏览器组件即将失去焦点时调用。例如，如果焦点在最后一个HTML元素上，并且用户按下了TAB键。)

指定者:

onTakeFocus 在接口中 CefFocusHandler

参数:

browser - The browser generating the event. (-浏览器生成事件。)
