    • Method Detail

      • onLoadingStateChange

        void onLoadingStateChange​(CefBrowser browser,
                          boolean isLoading,
                          boolean canGoBack,
                          boolean canGoForward)
        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.
        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

        void onLoadStart​(CefBrowser browser,
                 CefFrame frame,
                 CefRequest.TransitionType transitionType)
        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.
        frame - The frame generating the event. Instance only valid within the scope of this method.
        transitionType - The transition type.

      • onLoadEnd

        void onLoadEnd​(CefBrowser browser,
               CefFrame frame,
               int httpStatusCode)
        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.
        Parameters:
        browser - The corresponding browser.
        frame - The frame generating the event. Instance only valid within the scope of this method.
        httpStatusCode - The status code of the load.

      • onLoadError

        void onLoadError​(CefBrowser browser,
                 CefFrame frame,
                 CefLoadHandler.ErrorCode errorCode,
                 java.lang.String errorText,
                 java.lang.String failedUrl)
        Called when the resource load for a navigation fails or is canceled.
        Parameters:
        browser - The corresponding browser.
        frame - The frame generating the event. Instance only valid within the scope of this method.
        errorCode - The error code number.
