webkit_web_view_new ()

GtkWidget *
webkit_web_view_new (void);

Creates a new WebKitWebView with the default WebKitWebContext and no WebKitUserContentManager associated with it. See also webkit_web_view_new_with_context(), webkit_web_view_new_with_user_content_manager(), and webkit_web_view_new_with_settings().

webkit_web_view_new_with_context ()

GtkWidget *
webkit_web_view_new_with_context (WebKitWebContext *context);

Creates a new WebKitWebView with the given WebKitWebContext and no WebKitUserContentManager associated with it. See also webkit_web_view_new_with_user_content_manager() and webkit_web_view_new_with_settings().

webkit_web_view_new_with_related_view ()

GtkWidget *
webkit_web_view_new_with_related_view (WebKitWebView *web_view);

Creates a new WebKitWebView sharing the same web process with web_view . This method doesn't have any effect when WEBKIT_PROCESS_MODEL_SHARED_SECONDARY_PROCESS process model is used, because a single web process is shared for all the web views in the same WebKitWebContext. When using WEBKIT_PROCESS_MODEL_MULTIPLE_SECONDARY_PROCESSES process model, this method should always be used when creating the WebKitWebView in the “create” signal. You can also use this method to implement other process models based on WEBKIT_PROCESS_MODEL_MULTIPLE_SECONDARY_PROCESSES, like for example, sharing the same web process for all the views in the same security domain.

The newly created WebKitWebView will also have the same WebKitUserContentManager and WebKitSettings as web_view .

Retrieves the GTlsCertificate associated with the main resource of web_view , and the GTlsCertificateFlags showing what problems, if any, have been found with that certificate. If the connection is not HTTPS, this function returns FALSE. This function should be called after a response has been received from the server, so you can connect to “load-changed” and call this function when it's emitted with WEBKIT_LOAD_COMMITTED event.

Note that this function provides no information about the security of the web page if the current WebKitTLSErrorsPolicy is WEBKIT_TLS_ERRORS_POLICY_IGNORE , as subresources of the page may be controlled by an attacker. This function may safely be used to determine the security status of the current page only if the current WebKitTLSErrorsPolicy is WEBKIT_TLS_ERRORS_POLICY_FAIL , in which case subresources that fail certificate verification will be blocked.

               gpointer                     user_data)

This signal is emitted when the user is challenged with HTTP authentication. To let the application access or supply the credentials as well as to allow the client application to either cancel the request or perform the authentication, the signal will pass an instance of the WebKitAuthenticationRequest in the request argument. To handle this signal asynchronously you should keep a ref of the request and return TRUE. To disable HTTP authentication entirely, connect to this signal and simply return TRUE.

The default signal handler will run a default authentication dialog asynchronously for the user to interact with.

Flags: Run Last

Since: 2.2

The “close” signal

void
user_function (WebKitWebView *webView,
               gpointer       user_data)

The proposed WebKitContextMenu passed in context_menu argument is only valid during the signal emission.

Flags: Run Last

The “context-menu-dismissed” signal

void
user_function (WebKitWebView *web_view,
               gpointer       user_data)

Emitted after “context-menu” signal, if the context menu is shown, to notify that the context menu is dismissed.

Flags: Run Last

The “create” signal

GtkWidget*
user_function (WebKitWebView          *web_view,
               WebKitNavigationAction *navigation_action,
               gpointer                user_data)

Emitted when the creation of a new WebKitWebView is requested. If this signal is handled the signal handler should return the newly created WebKitWebView.

The WebKitNavigationAction parameter contains information about the navigation action that triggered this signal.

When using WEBKIT_PROCESS_MODEL_MULTIPLE_SECONDARY_PROCESSES process model, the new WebKitWebView should be related to web_view to share the same web process, see webkit_web_view_new_with_related_view() for more details.

The new WebKitWebView should not be displayed to the user until the “ready-to-show” signal is emitted.

The “decide-policy” signal

gboolean
user_function (WebKitWebView           *web_view,
               WebKitPolicyDecision    *decision,
               WebKitPolicyDecisionType decision_type,
               gpointer                 user_data)

This signal is emitted when WebKit is requesting the client to decide a policy decision, such as whether to navigate to a page, open a new window or whether or not to download a resource. The WebKitNavigationPolicyDecision passed in the decision argument is a generic type, but should be casted to a more specific type when making the decision. For example:

    switch (type) {
    case WEBKIT_POLICY_DECISION_TYPE_NAVIGATION_ACTION:
        WebKitNavigationPolicyDecision *navigation_decision = WEBKIT_NAVIGATION_POLICY_DECISION (decision);

        break;
    case WEBKIT_POLICY_DECISION_TYPE_RESPONSE:
        WebKitResponsePolicyDecision *response = WEBKIT_RESPONSE_POLICY_DECISION (decision);
        /* Make a policy decision here. */
        break;
    default:
        /* Making no decision results in webkit_policy_decision_use(). */
        return FALSE;
    }
    return TRUE;
}

It is possible to make policy decision asynchronously, by simply calling g_object_ref() on the decision argument and returning TRUE to block the default signal handler. If the last reference is removed on a WebKitPolicyDecision and no decision has been made explicitly, webkit_policy_decision_use() will be the default policy decision. The default signal handler will simply call webkit_policy_decision_use(). Only the first policy decision chosen for a given WebKitPolicyDecision will have any affect.

Flags: Run Last

The “enter-fullscreen” signal

gboolean
user_function (WebKitWebView *web_view,
               gpointer       user_data)

Emitted when JavaScript code calls element.webkitRequestFullScreen. If the signal is not handled the WebKitWebView will proceed to full screen its top level window. This signal can be used by client code to request permission to the user prior doing the full screen transition and eventually prepare the top-level window (e.g. hide some widgets that would otherwise be part of the full screen window).

Flags: Run Last

The “insecure-content-detected” signal

               WebKitInsecureContentEvent event,
               gpointer                   user_data)

This signal is emitted when insecure content has been detected in a page loaded through a secure connection. This typically means that a external resource from an unstrusted source has been run or displayed, resulting in a mix of HTTPS and non-HTTPS content.

You can check the event parameter to know exactly which kind of event has been detected (see WebKitInsecureContentEvent).

Flags: Run Last

The “leave-fullscreen” signal

gboolean
user_function (WebKitWebView *web_view,
               gpointer       user_data)

Emitted when the WebKitWebView is about to restore its top level window out of its full screen state. This signal can be used by client code to restore widgets hidden during the “enter-fullscreen” stage for instance.

Flags: Run Last

The “load-changed” signal

void
user_function (WebKitWebView  *web_view,
               WebKitLoadEvent load_event,
               gpointer        user_data)

Emitted when the a load operation in web_view changes. The signal is always emitted with WEBKIT_LOAD_STARTED when a new load request is made and WEBKIT_LOAD_FINISHED when the load finishes successfully or due to an error. When the ongoing load operation fails “load-failed” signal is emitted before “load-changed” is emitted with WEBKIT_LOAD_FINISHED. If a redirection is received from the server, this signal is emitted with WEBKIT_LOAD_REDIRECTED after the initial emission with WEBKIT_LOAD_STARTED and before WEBKIT_LOAD_COMMITTED. When the page content starts arriving the signal is emitted with WEBKIT_LOAD_COMMITTED event.

You can handle this signal and use a switch to track any ongoing load operation.

Emitted when an error occurs during a load operation. If the error happened when starting to load data for a page load_event will be WEBKIT_LOAD_STARTED. If it happened while loading a committed data source load_event will be WEBKIT_LOAD_COMMITTED. Since a load error causes the load operation to finish, the signal WebKitWebView::load-changed will always be emitted with WEBKIT_LOAD_FINISHED event right after this one.

By default, if the signal is not handled, a stock error page will be displayed. You need to handle the signal if you want to provide your own error page.

The “load-failed-with-tls-errors” signal

gboolean
user_function (WebKitWebView       *web_view,
               gchar               *failing_uri,
               GTlsCertificate     *certificate,
               GTlsCertificateFlags errors,
               gpointer             user_data)

Emitted when a TLS error occurs during a load operation. To allow an exception for this certificate and the host of failing_uri use webkit_web_context_allow_tls_certificate_for_host().

To handle this signal asynchronously you should call g_object_ref() on certificate and return TRUE.

If FALSE is returned, “load-failed” will be emitted. The load will finish regardless of the returned value.

The “mouse-target-changed” signal

void
user_function (WebKitWebView       *web_view,
               WebKitHitTestResult *hit_test_result,
               guint                modifiers,
               gpointer             user_data)

This signal is emitted when the mouse cursor moves over an element such as a link, image or a media element. To determine what type of element the mouse cursor is over, a Hit Test is performed on the current mouse coordinates and the result is passed in the hit_test_result argument. The modifiers argument is a bitmask of GdkModifierType flags indicating the state of modifier keys. The signal is emitted again when the mouse is moved out of the current element with a new hit_test_result .

The “permission-request” signal

gboolean
user_function (WebKitWebView           *web_view,
               WebKitPermissionRequest *request,
               gpointer                 user_data)

This signal is emitted when WebKit is requesting the client to decide about a permission request, such as allowing the browser to switch to fullscreen mode, sharing its location or similar operations.

A possible way to use this signal could be through a dialog allowing the user decide what to do with the request:

                                                GTK_MESSAGE_QUESTION,
                                                GTK_BUTTONS_YES_NO,
                                                "Allow Permission Request?");
    gtk_widget_show (dialog);
    gint result = gtk_dialog_run (GTK_DIALOG (dialog));

    switch (result) {
    case GTK_RESPONSE_YES:
        webkit_permission_request_allow (request);
        break;
    default:
        webkit_permission_request_deny (request);
        break;
    }
    gtk_widget_destroy (dialog);

    return TRUE;
}

It is possible to handle permission requests asynchronously, by simply calling g_object_ref() on the request argument and returning TRUE to block the default signal handler. If the last reference is removed on a WebKitPermissionRequest and the request has not been handled, webkit_permission_request_deny() will be the default action.

By default, if the signal is not handled, webkit_permission_request_deny() will be called over the WebKitPermissionRequest.

The “print” signal

gboolean
user_function (WebKitWebView        *web_view,
               WebKitPrintOperation *print_operation,
               gpointer              user_data)

Emitted when printing is requested on web_view , usually by a javascript call, before the print dialog is shown. This signal can be used to set the initial print settings and page setup of print_operation to be used as default values in the print dialog. You can call webkit_print_operation_set_print_settings() and webkit_print_operation_set_page_setup() and then return FALSE to propagate the event so that the print dialog is shown.

You can connect to this signal and return TRUE to cancel the print operation or implement your own print dialog.

The “ready-to-show” signal

void
user_function (WebKitWebView *web_view,
               gpointer       user_data)

Emitted after “create” on the newly created WebKitWebView when it should be displayed to the user. When this signal is emitted all the information about how the window should look, including size, position, whether the location, status and scrollbars should be displayed, is already set on the WebKitWindowProperties of web_view . See also webkit_web_view_get_window_properties().

The “resource-load-started” signal

void
user_function (WebKitWebView     *web_view,
               WebKitWebResource *resource,
               WebKitURIRequest  *request,
               gpointer           user_data)

Emitted when a new resource is going to be loaded. The request parameter contains the WebKitURIRequest that will be sent to the server. You can monitor the load operation by connecting to the different signals of resource .

The “run-as-modal” signal

void
user_function (WebKitWebView *web_view,
               gpointer       user_data)

Emitted after “ready-to-show” on the newly created WebKitWebView when JavaScript code calls window.showModalDialog. The purpose of this signal is to allow the client application to prepare the new view to behave as modal. Once the signal is emitted a new mainloop will be run to block user interaction in the parent WebKitWebView until the new dialog is closed.

The “run-color-chooser” signal

gboolean
user_function (WebKitWebView             *web_view,
               WebKitColorChooserRequest *request,
               gpointer                   user_data)

This signal is emitted when the user interacts with a <input type='color' /> HTML element, requesting from WebKit to show a dialog to select a color. To let the application know the details of the color chooser, as well as to allow the client application to either cancel the request or perform an actual color selection, the signal will pass an instance of the WebKitColorChooserRequest in the request argument.

It is possible to handle this request asynchronously by increasing the reference count of the request.

The default signal handler will asynchronously run a regular GtkColorChooser for the user to interact with.

The “run-file-chooser” signal

gboolean
user_function (WebKitWebView            *web_view,
               WebKitFileChooserRequest *request,
               gpointer                  user_data)

This signal is emitted when the user interacts with a <input type='file' /> HTML element, requesting from WebKit to show a dialog to select one or more files to be uploaded. To let the application know the details of the file chooser, as well as to allow the client application to either cancel the request or perform an actual selection of files, the signal will pass an instance of the WebKitFileChooserRequest in the request argument.

The default signal handler will asynchronously run a regular GtkFileChooserDialog for the user to interact with.

The “script-dialog” signal

gboolean
user_function (WebKitWebView      *web_view,
               WebKitScriptDialog *dialog,
               gpointer            user_data)

Emitted when JavaScript code calls window.alert, window.confirm or window.prompt. The dialog parameter should be used to build the dialog. If the signal is not handled a different dialog will be built and shown depending on the dialog type:

Flags: Run Last

The “show-notification” signal

gboolean
user_function (WebKitWebView      *web_view,
               WebKitNotification *notification,
               gpointer            user_data)

This signal is emitted when a notification should be presented to the user. The notification is kept alive until either: 1) the web page cancels it or 2) a navigation happens.

The default handler will emit a notification using libnotify, if built with support for it.

The “submit-form” signal

void
user_function (WebKitWebView               *web_view,
               WebKitFormSubmissionRequest *request,
               gpointer                     user_data)

This signal is emitted when a form is about to be submitted. The request argument passed contains information about the text fields of the form. This is typically used to store login information that can be used later to pre-fill the form. The form will not be submitted until webkit_form_submission_request_submit() is called.

It is possible to handle the form submission request asynchronously, by simply calling g_object_ref() on the request argument and calling webkit_form_submission_request_submit() when done to continue with the form submission. If the last reference is removed on a WebKitFormSubmissionRequest and the form has not been submitted, webkit_form_submission_request_submit() will be called.
