        public void onLoadingStateChange​(CefBrowser browser,
                                 boolean isLoading,
                                 boolean canGoBack,
                                 boolean canGoForward)
        Description copied from interface: CefLoadHandler
        Called when the loading state has changed. This callback will be executed twice -- once when loading is initiated either programmatically or by user action, and once when loading is terminated due to completion, cancellation of failure.
        Specified by:
        onLoadingStateChange in interface CefLoadHandler
        Parameters:
        browser - The corresponding browser.
        isLoading - true if it is loading.
        canGoBack - true if you can navigate back.
        canGoForward - true if you can navigate forward.

      • onLoadStart

        public void onLoadStart​(CefBrowser browser,
                        CefFrame frame,
                        CefRequest.TransitionType transitionType)
        Description copied from interface: CefLoadHandler
        Called when the browser begins loading a frame. The frameIdentifer value will never be empty. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method may not be called for a particular frame if the load request for that frame fails. For notification of overall browser load status use onLoadingStateChange instead.

        Parameters:
        browser - The corresponding browser.

                      int httpStatusCode)
        Description copied from interface: CefLoadHandler
        Called when the browser is done loading a frame. The frameIdentifer value will never be empty. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method will always be called for all frames irrespective of whether the request completes successfully.
