Member Function Documentation
◆ GetAuthCredentials()
|
inlinevirtual |
Called on the IO thread when the browser needs credentials from the user.
|origin_url| is the origin making this authentication request. |isProxy| indicates whether the host is a proxy server. |host| contains the hostname and |port| contains the port number. |realm| is the realm of the challenge and may be empty. |scheme| is the authentication scheme used, such as "basic" or "digest", and will be empty if the source of the request is an FTP server. Return true to continue the request and call CefAuthCallback::Continue() either in this method or at a later time when the authentication information is available. Return false to cancel the request immediately.
◆ GetResourceRequestHandler()
|
inlinevirtual |
Called on the browser process IO thread before a resource request is initiated.
The |browser| and |frame| values represent the source of the request. |request| represents the request contents and cannot be modified in this callback. |is_navigation| will be true if the resource request is a navigation. |is_download| will be true if the resource request is a download. |request_initiator| is the origin (scheme + domain) of the page that initiated the request. Set |disable_default_handling| to true to disable default handling of the request, in which case it will need to be handled via CefResourceRequestHandler::GetResourceHandler or it will be canceled. To allow the resource load to proceed with default handling return NULL. To specify a handler for the resource return a CefResourceRequestHandler object. If this callback returns NULL the same method will be called on the associated CefRequestContextHandler, if any.
◆ OnBeforeBrowse()
|
inlinevirtual |
Called on the UI thread before browser navigation.
Return true to cancel the navigation or false to allow the navigation to proceed. The |request| object cannot be modified in this callback. CefLoadHandler::OnLoadingStateChange will be called twice in all cases. If the navigation is allowed CefLoadHandler::OnLoadStart and CefLoadHandler::OnLoadEnd will be called. If the navigation is canceled CefLoadHandler::OnLoadError will be called with an |errorCode| value of ERR_ABORTED. The |user_gesture| value will be true if the browser navigated via explicit user gesture (e.g. clicking a link) or false if it navigated automatically (e.g. via the DomContentLoaded event).
◆ OnCertificateError()
|
inlinevirtual |
Called on the UI thread to handle requests for URLs with an invalid SSL certificate.
Return true and call CefCallback methods either in this method or at a later time to continue or cancel the request. Return false to cancel the request immediately. If cef_settings_t.ignore_certificate_errors is set all invalid certificates will be accepted without calling this method.
◆ OnDocumentAvailableInMainFrame()
|
inlinevirtual |
Called on the browser process UI thread when the window.document object of the main frame has been created.
◆ OnOpenURLFromTab()
|
inlinevirtual |
Called on the UI thread before OnBeforeBrowse in certain limited cases where navigating a new or different browser might be desirable.
This includes user-initiated navigation that might open in a special way (e.g. links clicked via middle-click or ctrl + left-click) and certain types of cross-origin navigation initiated from the renderer process (e.g. navigating the top-level frame to/from a file URL). The |browser| and |frame| values represent the source of the navigation. The |target_disposition| value indicates where the user intended to navigate the browser based on standard Chromium behaviors (e.g. current tab, new tab, etc). The |user_gesture| value will be true if the browser navigated via explicit user gesture (e.g. clicking a link) or false if it navigated automatically (e.g. via the DomContentLoaded event). Return true to cancel the navigation or false to allow the navigation to proceed in the source browser's top-level frame.
◆ OnRenderProcessTerminated()
|
inlinevirtual |
Called on the browser process UI thread when the render process terminates unexpectedly.
|status| indicates how the process terminated.
◆ OnRenderViewReady()
|
inlinevirtual |
Called on the browser process UI thread when the render view associated with |browser| is ready to receive/handle IPC messages in the render process.
◆ OnSelectClientCertificate()
|
inlinevirtual |
Called on the UI thread when a client certificate is being requested for authentication.
Return false to use the default behavior and automatically select the first certificate available. Return true and call CefSelectClientCertificateCallback::Select either in this method or at a later time to select a certificate. Do not call Select or call it with NULL to continue without using any certificate. |isProxy| indicates whether the host is an HTTPS proxy or the origin server. |host| and |port| contains the hostname and port of the SSL server. |certificates| is the list of certificates to choose from; this list has already been pruned by Chromium so that it only contains certificates from issuers that the server trusts.
