The LoadListener provides methods for receiving browser load events. You can use this listener to get notifications about web page loading events, document availability events, loading failure events etc. The following code demonstrates how to register LoadListener:(LoadListener提供了用于接收浏览器加载事件的方法。您可以使用此侦听器获取有关网页加载事件，文档可用性事件，加载失败事件等的通知。以下代码演示了如何注册LoadListener：)

browser.addLoadListener(new LoadAdapter() {
    @Override
    public void onStartLoadingFrame(StartLoadingEvent event) {
        if (event.isMainFrame()) {
            System.out.println("Main frame has started loading");
        }
    }

    @Override
    public void onProvisionalLoadingFrame(ProvisionalLoadingEvent event) {
        if (event.isMainFrame()) {
            System.out.println("Provisional load was committed for a frame");
        }
    }

    @Override
    public void onFinishLoadingFrame(FinishLoadingEvent event) {
        if (event.isMainFrame()) {
            System.out.println("Main frame has finished loading");
        }
    }

    @Override
    public void onFailLoadingFrame(FailLoadingEvent event) {
        NetError errorCode = event.getErrorCode();
        if (event.isMainFrame()) {
            System.out.println("Main frame has failed loading: " + errorCode);
        }
    }

    @Override
    public void onDocumentLoadedInFrame(FrameLoadEvent event) {
        System.out.println("Frame document is loaded.");
    }

    @Override
    public void onDocumentLoadedInMainFrame(LoadEvent event) {
        System.out.println("Main frame document is loaded.");
    }
});
