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.
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()
.
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()
.
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
.
[constructor]
Since: 2.4
GtkWidget *
webkit_web_view_new_with_settings (WebKitSettings *settings
);
Creates a new WebKitWebView with the given WebKitSettings.

Since: 2.6
gboolean
webkit_web_view_is_ephemeral (WebKitWebView *web_view
);
Get whether a WebKitWebView is ephemeral. To create an ephemeral WebKitWebView you need to
use g_object_new()
and pass is-ephemeral property with TRUE
value. See
“is-ephemeral” for more details.
If web_view
was created with a ephemeral “related-view” or an
ephemeral “web-context” it will also be ephemeral.
Since: 2.16
gboolean
webkit_web_view_is_controlled_by_automation
(WebKitWebView *web_view
);
Get whether a WebKitWebView was created with “is-controlled-by-automation” property enabled. Only WebKitWebViews controlled by automation can be used in an automation session.
Since: 2.18
WebKitWebContext *
webkit_web_view_get_context (WebKitWebView *web_view
);
Gets the web context of web_view
.
WebKitUserContentManager *

's WebKitWebContext.
Since: 2.16
void
webkit_web_view_try_close (WebKitWebView *web_view
);
Tries to close the web_view
. This will fire the onbeforeunload event
to ask the user for confirmation to close the page. If there isn't an
onbeforeunload event handler or the user confirms to close the page,
the “close” signal is emitted, otherwise nothing happens.
Since: 2.12
void webkit_web_view_load_uri (WebKitWebView *web_view
,const gchar *uri
);
Requests loading of the specified URI string. You can monitor the load operation by connecting to “load-changed” signal.
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.
web_view |
||

string for the URI content_uri
.
This allows clients to display page-loading errors in the WebKitWebView itself.
When this method is called from “load-failed” signal to show an
error page, then the back-forward list is maintained appropriately.
For everything else this method works the same way as webkit_web_view_load_html()
.
web_view |

error.
gboolean
webkit_web_view_is_loading (WebKitWebView *web_view
);
Gets the value of the “is-loading” property.
You can monitor when a WebKitWebView is loading a page by connecting to
notify::is-loading signal of web_view
. This is useful when you are
interesting in knowing when the view is loading something but not in the
details about the status of the load operation, for example to start a spinner
when the view is loading a page and stop it when it finishes.
gboolean
webkit_web_view_is_playing_audio (WebKitWebView *web_view
);
Gets the value of the “is-playing-audio” property.
You can monitor when a page in a WebKitWebView is playing audio by
connecting to the notify::is-playing-audio signal of web_view

);
Obtains the WebKitBackForwardList associated with the given WebKitWebView. The WebKitBackForwardList is owned by the WebKitWebView.
void webkit_web_view_go_to_back_forward_list_item (WebKitWebView *web_view
,WebKitBackForwardListItem *list_item
);
Loads the specific history item list_item
.
You can monitor the load operation by connecting to
“load-changed” signal.
const gchar *
webkit_web_view_get_uri (WebKitWebView *web_view
);
Returns the current active URI of web_view
. The active URI might change during
a load operation:
When nothing has been loaded yet on web_view
the active URI is NULL
.
When a new load operation starts the active URI is the requested URI:
If the load operation was started by webkit_web_view_load_uri()
,
the requested URI is the given one.
If the load operation was started by webkit_web_view_load_html()
,
the requested URI is "about:blank".
If the load operation was started by webkit_web_view_load_alternate_html()
,
the requested URI is content URI provided.
If the load operation was started by webkit_web_view_go_back()
or
webkit_web_view_go_forward()
, the requested URI is the original URI
of the previous/next item in the WebKitBackForwardList of web_view
.
If the load operation was started by
webkit_web_view_go_to_back_forward_list_item()
, the requested URI
is the opriginal URI of the given WebKitBackForwardListItem.
If there is a server redirection during the load operation,
the active URI is the redirected URI. When the signal
“load-changed” is emitted with WEBKIT_LOAD_REDIRECTED
event, the active URI is already updated to the redirected URI.
When the signal “load-changed” is emitted
with WEBKIT_LOAD_COMMITTED
event, the active URI is the final
one and it will not change unless a new load operation is started
or a navigation action within the same page is performed.
You can monitor the active URI by connecting to the notify::uri
signal of web_view
.
cairo_surface_t *
webkit_web_view_get_favicon (WebKitWebView *web_view
);

settings
. New settings are applied immediately on web_view
.
The same WebKitSettings object can be shared
by multiple WebKitWebViews.
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.

“authenticate”
signalgboolean 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.

“context-menu”
signalgboolean 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.
To customize the proposed menu you can use webkit_context_menu_prepend()
,
webkit_context_menu_append()
or webkit_context_menu_insert()
to add new
WebKitContextMenuItems to context_menu
, webkit_context_menu_move_item()
to reorder existing items, or webkit_context_menu_remove()
to remove an
existing item. The signal handler should return FALSE
, and the menu represented
by context_menu
will be shown.
To prevent the menu from being displayed you can just connect to this signal
and return TRUE
so that the proposed menu will not be shown.
To build your own menu, you can remove all items from the proposed menu with
webkit_context_menu_remove_all()
, add your own items and return FALSE
so
that the menu will be shown. You can also ignore the proposed WebKitContextMenu,
build your own GtkMenu and return TRUE
to prevent the proposed menu from being shown.
If you just want the default menu to be shown always, simply don't connect to this signal because showing the proposed context menu is the default behaviour.
The event
is expected to be one of the following types:
a GdkEventButton of type GDK_BUTTON_PRESS
when the context menu
was triggered with mouse.
a GdkEventKey of type GDK_KEY_PRESS
if the keyboard was used to show
the menu.
a generic GdkEvent of type GDK_NOTHING
when the “popup-menu”
signal was used to show the context menu.
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.

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

“decide-policy”
signalgboolean 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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |

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.

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).

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

“load-failed”
signalgboolean user_function (WebKitWebView *web_view, WebKitLoadEvent load_event, gchar *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.

“mouse-target-changed”
signalvoid 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
.

“permission-request”
signalgboolean 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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |

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.

“print”
signalgboolean 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.

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

. 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.

“run-color-chooser”
signalgboolean 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.

“script-dialog”
signalgboolean user_function (WebKitWebView *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:
WEBKIT_SCRIPT_DIALOG_ALERT
: message dialog with a single Close button.
WEBKIT_SCRIPT_DIALOG_CONFIRM
: message dialog with OK and Cancel buttons.
WEBKIT_SCRIPT_DIALOG_PROMPT
: message dialog with OK and Cancel buttons and
a text entry with the default text.
WEBKIT_SCRIPT_DIALOG_BEFORE_UNLOAD_CONFIRM
: message dialog with Stay and Leave buttons.
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.

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. If this was triggered by a user interaction, like a mouse click,
event
parameter provides the GdkEvent.
To handle this signal asynchronously you should keep a ref of the menu
.

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
