Method Detail

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.

errorText - The error text.

failedUrl - The URL that failed to load.

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.
