Method Detail

onJSDialog

public boolean onJSDialog(CefBrowser browser,
                          java.lang.String origin_url,
                          CefJSDialogHandler.JSDialogType dialog_type,
                          java.lang.String message_text,
                          java.lang.String default_prompt_text,
                          CefJSDialogCallback callback,
                          BoolRef suppress_message)

Description copied from interface: CefJSDialogHandler

Called to run a JavaScript dialog. Set suppress_message to true and return false to suppress the message (suppressing messages is preferable to immediately executing the callback as this is used to detect presumably malicious behavior like spamming alert messages in onbeforeunload). Set suppress_message to false and return false to use the default implementation (the default implementation will show one modal dialog at a time and suppress any additional dialog requests until the displayed dialog is dismissed). Return true if the application will use a custom dialog or if the callback has been executed immediately. Custom dialogs may be either modal or modeless. If a custom dialog is used the application must execute callback once the custom dialog is dismissed.

Specified by:

onJSDialog in interface CefJSDialogHandler

Parameters:

browser - The corresponding browser.

origin_url - The originating url.

dialog_type - the dialog type.

message_text - the text to be displayed.

default_prompt_text - value will be specified for prompt dialogs only.

callback - execute callback once the custom dialog is dismissed.

suppress_message - set to true to suppress displaying the message.

Returns:

false to use the default dialog implementation. Return true if the application will use a custom dialog.

onBeforeUnloadDialog

public boolean onBeforeUnloadDialog(CefBrowser browser,
                                    java.lang.String message_text,
                                    boolean is_reload,
                                    CefJSDialogCallback callback)

Description copied from interface: CefJSDialogHandler

Called to run a dialog asking the user if they want to leave a page. Return false to use the default dialog implementation. Return true if the application will use a custom dialog or if the callback has been executed immediately. Custom dialogs may be either modal or modeless. If a custom dialog is used the application must execute callback once the custom dialog is dismissed.

Specified by:

onBeforeUnloadDialog in interface CefJSDialogHandler

Parameters:

browser - The corresponding browser.

message_text - The text to be displayed.

is_reload - true if the page is reloaded.

Description copied from interface: CefJSDialogHandler

Specified by:

onResetDialogState in interface CefJSDialogHandler

onDialogClosed

public void onDialogClosed(CefBrowser browser)

Description copied from interface: CefJSDialogHandler

Called when the default implementation dialog is closed.

Specified by:
