Implemented Interfaces

WebKitWebView implements AtkImplementorIface and GtkBuildable.

Description

WebKitWebView is the central class of the WPE WebKit and WebKitGTK APIs. It is responsible for managing the drawing of the content and forwarding of events. You can load any URI into the WebKitWebView or a data string. With WebKitSettings you can control various aspects of the rendering and loading of the content.

Note that in WebKitGTK, WebKitWebView is scrollable by itself, so you don't need to embed it in a GtkScrolledWindow.

Functions

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().

Returns

The newly created WebKitWebView widget


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().

Parameters

context

the WebKitWebContext to be used by the WebKitWebView

 

Returns

The newly created WebKitWebView widget


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, WebKitSettings, and WebKitWebsitePolicies as web_view .

Requests loading of the specified URI string. You can monitor the load operation by connecting to “load-changed” signal.

Parameters

web_view

a WebKitWebView

 

uri

an URI string

 

webkit_web_view_load_html ()

void
webkit_web_view_load_html (WebKitWebView *web_view,
                           const gchar *content,
                           const gchar *base_uri);

Load the given content string with the specified base_uri . If base_uri is not NULL, relative URLs in the content will be resolved against base_uri and absolute local paths must be children of the base_uri . For security reasons absolute local paths that are not children of base_uri will cause the web process to terminate. If you need to include URLs in content that are local paths in a different directory than base_uri you can build a data URI for them. When base_uri is NULL, it defaults to "about:blank". The mime type of the document will be "text/html". You can monitor the load operation by connecting to “load-changed” signal.

Parameters

web_view

a WebKitWebView

 

content

The HTML string to load

 

base_uri

The base URI for relative locations or NULL.

webkit_web_view_get_settings ()

WebKitSettings *
webkit_web_view_get_settings (WebKitWebView *web_view);

Gets the WebKitSettings currently applied to web_view . If no other WebKitSettings have been explicitly applied to web_view with webkit_web_view_set_settings(), the default WebKitSettings will be returned. This method always returns a valid WebKitSettings object. To modify any of the web_view settings, you can either create a new WebKitSettings object with webkit_settings_new(), setting the desired preferences, and then replace the existing web_view settings with webkit_web_view_set_settings() or get the existing web_view settings and update it directly. WebKitSettings objects can be shared by multiple WebKitWebViews, so modifying the settings of a WebKitWebView would affect other WebKitWebViews using the same WebKitSettings.

Members

WEBKIT_LOAD_STARTED

A new load request has been made. No data has been received yet, empty structures have been allocated to perform the load; the load may still fail due to transport issues such as not being able to resolve a name, or connect to a port.

 

WEBKIT_LOAD_REDIRECTED

A provisional data source received a server redirect.

 

WEBKIT_LOAD_COMMITTED

The content started arriving for a page load. The necessary transport requirements are established, and the load is being performed.

Signal Details

The “authenticate” signal

gboolean
user_function (WebKitWebView               *web_view,
               WebKitAuthenticationRequest *request,
               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.

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

request

a WebKitAuthenticationRequest

 

user_data

user data set when the signal handler was connected.

 

Returns

TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further.

Flags: Run Last

Since: 2.2


The “close” signal

void
user_function (WebKitWebView *web_view,
               gpointer       user_data)

Emitted when closing a WebKitWebView is requested. This occurs when a call is made from JavaScript's window.close function or after trying to close the web_view with webkit_web_view_try_close(). It is the owner's responsibility to handle this signal to hide or destroy the WebKitWebView, if necessary.

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

user_data

user data set when the signal handler was connected.

 

Flags: Run Last


The “context-menu” signal

gboolean
user_function (WebKitWebView       *web_view,
               WebKitContextMenu   *context_menu,
               GdkEvent            *event,
               WebKitHitTestResult *hit_test_result,
               gpointer             user_data)

Emitted when a context menu is about to be displayed to give the application a chance to customize the proposed menu, prevent the menu from being displayed, or build its own context menu.

The event is expected to be one of the following types:

If the signal handler returns FALSE the context menu represented by context_menu will be shown, if it return TRUE the context menu will not be shown.

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

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

context_menu

the proposed WebKitContextMenu

 

event

the GdkEvent that triggered the context menu

 

hit_test_result

a WebKitHitTestResult

 

user_data

user data set when the signal handler was connected.

 

Returns

TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further.

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.

Parameters

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.

The new WebKitWebView must be related to web_view , 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.

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

navigation_action

a WebKitNavigationAction

 

user_data

user data set when the signal handler was connected.

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:

                  WebKitPolicyDecision *decision,
                  WebKitPolicyDecisionType type)
{
    switch (type) {
    case WEBKIT_POLICY_DECISION_TYPE_NAVIGATION_ACTION: {
        WebKitNavigationPolicyDecision *navigation_decision = WEBKIT_NAVIGATION_POLICY_DECISION (decision);
        /* Make a policy decision here. */
        break;
    }
    case WEBKIT_POLICY_DECISION_TYPE_NEW_WINDOW_ACTION: {
        WebKitNavigationPolicyDecision *navigation_decision = WEBKIT_NAVIGATION_POLICY_DECISION (decision);
        /* Make a policy decision here. */
        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.

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

decision

the WebKitPolicyDecision

 

decision_type

a WebKitPolicyDecisionType denoting the type of decision

 

user_data

user data set when the signal handler was connected.

 

Returns

TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further.

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).

Parameters

web_view

the WebKitWebView on which the signal is emitted.

 

user_data

user data set when the signal handler was connected.

 

Returns

TRUE to stop other handlers from being invoked for the event. FALSE to continue emission of the event.

Flags: Run Last


The “insecure-content-detected” signal

void
user_function (WebKitWebView             *web_view,
               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).

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

event

the WebKitInsecureContentEvent

 

user_data

user data set when the signal handler was connected.

 

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.

Parameters

web_view

the WebKitWebView on which the signal is emitted.

 

user_data

user data set when the signal handler was connected.

 

Returns

TRUE to stop other handlers from being invoked for the event. FALSE to continue emission of the event.

The “load-changed” signal

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

Emitted when 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.

The “load-failed” signal

gboolean
user_function (WebKitWebView  *web_view,
               WebKitLoadEvent load_event,
               char           *failing_uri,
               GError         *error,
               gpointer        user_data)

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.

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

load_event

the WebKitLoadEvent of the load operation

 

failing_uri

the URI that failed to load

 

error

the GError that was triggered

 

user_data

user data set when the signal handler was connected.

 

Returns

TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further.

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

gboolean
user_function (WebKitWebView       *web_view,
               char                *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.

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

failing_uri

the URI that failed to load

 

certificate

a GTlsCertificate

 

errors

a GTlsCertificateFlags with the verification status of certificate

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 .

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

hit_test_result

a WebKitHitTestResult

 

modifiers

a bitmask of GdkModifierType

 

user_data

    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.

If the signal is not handled, the request will be completed automatically by the specific WebKitPermissionRequest that could allow or deny it. Check the documentation of classes implementing WebKitPermissionRequest interface to know their default action.

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

request

the WebKitPermissionRequest

 

user_data

user data set when the signal handler was connected.

 

Returns

TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further.

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.

Parameters

the WebKitWebView on which the signal is emitted

 

print_operation

the WebKitPrintOperation that will handle the print request

 

user_data

user data set when the signal handler was connected.

 

Returns

TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further.

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 main loop will be run to block user interaction in the parent WebKitWebView until the new dialog is closed.

Parameters

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.

Parameters

web_view

               WebKitScriptDialog *dialog,
               gpointer            user_data)

Emitted when JavaScript code calls window.alert, window.confirm or window.prompt, or when onbeforeunload event is fired. 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:

It is possible to handle the script dialog request asynchronously, by simply caling webkit_script_dialog_ref() on the dialog argument and calling webkit_script_dialog_close() when done. If the last reference is removed on a WebKitScriptDialog and the dialog has not been closed, webkit_script_dialog_close() will be called.

Parameters

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.

Parameters

web_view

the WebKitWebView

 

notification

a WebKitNotification

 

user_data

user data set when the signal handler was connected.

 

Returns

TRUE to stop other handlers from being invoked. FALSE otherwise.

The “show-option-menu” signal

gboolean
user_function (WebKitWebView    *web_view,
               WebKitOptionMenu *menu,
               GdkEvent         *rectangle,
               GdkRectangle     *Returns,
               gpointer          user_data)

This signal is emitted when a select element in web_view needs to display a dropdown menu. This signal can be used to show a custom menu, using menu to get the details of all items that should be displayed. The area of the element in the WebKitWebView is given as rectangle parameter, it can be used to position the menu. To handle this signal asynchronously you should keep a ref of the menu .

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

menu

the WebKitOptionMenu

 

rectangle

the option element area

 

user_data

user data set when the signal handler was connected.

 

Returns

TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further.

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.

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

request

a WebKitFormSubmissionRequest

 

user_data

user data set when the signal handler was connected.

 

Flags: Run Last


The “user-message-received” signal

gboolean
user_function (WebKitWebView     *web_view,
               WebKitUserMessage *message,
               gpointer           user_data)

This signal is emitted when a WebKitUserMessage is received from the WebKitWebPage corresponding to web_view . You can reply to the message using webkit_user_message_send_reply().

You can handle the user message asynchronously by calling g_object_ref() on message and returning TRUE. If the last reference of message is removed and the message has not been replied to, the operation in the WebKitWebPage will finish with error WEBKIT_USER_MESSAGE_UNHANDLED_MESSAGE.

Parameters

web_view

the WebKitWebView on which the signal is emitted

 

message

the WebKitUserMessage received

 

user_data

user data set when the signal handler was connected.

 

Returns

TRUE if the message was handled, or FALSE otherwise.
