Class
WebKit2WebView
Description [src]
class WebKit2.WebView : WebKit2.WebViewBase
implements Atk.ImplementorIface, Gtk.Buildable {
priv: WebKitWebViewPrivate*
}The central class of the WPE WebKit and WebKitGTK APIs.
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.

Properties
WebKit2.WebView:automation-presentation-type
The WebKitAutomationBrowsingContextPresentation of WebKitWebView. This should only be used when
creating a new WebKitWebView as a response to WebKitAutomationSession::create-web-view
signal request. If the new WebView was added to a new tab of current browsing context window
WEBKIT_AUTOMATION_BROWSING_CONTEXT_PRESENTATION_TAB should be used.
since: 2.28
WebKit2.WebView:camera-capture-state
Capture state of the camera device. Whenever the user grants a media-request sent by the web
page, requesting video capture capabilities (navigator.mediaDevices.getUserMedia({video:
true})) this property will be set to WEBKIT_MEDIA_CAPTURE_STATE_ACTIVE.
since: 2.34
WebKit2.WebView:default-content-security-policy
The default Content-Security-Policy used by the webview as if it were set by an HTTP header.
since: 2.38
WebKit2.WebView:display-capture-state
Capture state of the display device. Whenever the user grants a media-request sent by the web
page, requesting screencasting capabilities (navigator.mediaDevices.getDisplayMedia() this
property will be set toWEBKIT_MEDIA_CAPTURE_STATE_ACTIVE`.
since: 2.34
WebKit2.WebView:editable
Whether the pages loaded inside WebKitWebView are editable. For more
information see webkit_web_view_set_editable().
since: 2.8
WebKit2.WebView:estimated-load-progress
An estimate of the percent completion for the current loading operation. This value will range from 0.0 to 1.0 and, once a load completes, will remain at 1.0 until a new load starts, at which point it will be reset to 0.0. The value is an estimate based on the total number of bytes expected to be received for a document, including all its possible subresources and child documents.
WebKit2.WebView:favicon
The favicon currently associated to the WebKitWebView.
See webkit_web_view_get_favicon() for more details.
WebKit2.WebView:is-controlled-by-automation
Whether the WebKitWebView is controlled by automation. This should only be used when
creating a new WebKitWebView as a response to WebKitAutomationSession::create-web-view
signal request.
since: 2.18
WebKit2.WebView:is-ephemeral
Whether the WebKitWebView is ephemeral. An ephemeral web view never writes
website data to the client storage, no matter what WebKitWebsiteDataManager
its context is using. This is normally used to implement private browsing mode.
This is a G_PARAM_CONSTRUCT_ONLY property, so you have to create an ephemeral
WebKitWebView and it can’t be changed. The ephemeral WebKitWebsiteDataManager
created for the WebKitWebView will inherit the network settings from the
WebKitWebContext‘s WebKitWebsiteDataManager. To use different settings
you can get the WebKitWebsiteDataManager with webkit_web_view_get_website_data_manager()
and set the new ones.
Note that all WebKitWebViews created with an ephemeral WebKitWebContext
will be ephemeral automatically.
See also webkit_web_context_new_ephemeral().
since: 2.16
WebKit2.WebView:is-loading
Whether the WebKitWebView is currently loading a page. This property becomes
TRUE as soon as a new load operation is requested and before the
WebKitWebView::load-changed signal is emitted with WEBKIT_LOAD_STARTED and
at that point the active URI is the requested one.
When the load operation finishes the property is set to FALSE before
WebKitWebView::load-changed is emitted with WEBKIT_LOAD_FINISHED.
WebKit2.WebView:is-muted
Whether the WebKitWebView audio is muted. When TRUE, audio is silenced.
It may still be playing, i.e. WebKitWebView:is-playing-audio may be TRUE.
since: 2.30
WebKit2.WebView:is-playing-audio
Whether the WebKitWebView is currently playing audio from a page.
This property becomes TRUE as soon as web content starts playing any
kind of audio. When a page is no longer playing any kind of sound,
the property is set back to FALSE.

Signals
WebKit2.WebView::authenticate
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.
since: 2.2
WebKit2.WebView::close
Emitted when closing a WebKitWebView is requested. This occurs when a
call is made from JavaScript’s 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.
WebKit2.WebView::context-menu
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.
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.
TRUE so that the proposed menu will not be shown.
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.
WebKit2.WebView::context-menu-dismissed
Emitted after WebKitWebView::context-menu signal, if the context menu is shown,
to notify that the context menu is dismissed.
WebKit2.WebView::create
Emitted when the creation of a new WebKitWebView is requested.
If this signal is handled the signal handler should return the
newly created WebKitWebView.
WebKit2.WebView::decide-policy
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:
WebKit2.WebView::enter-fullscreen
Emitted when JavaScript code calls
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).
WebKit2.WebView::insecure-content-detected
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.
WebKit2.WebView::leave-fullscreen
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
WebKitWebView::enter-fullscreen stage for instance.
WebKit2.WebView::load-changed
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 WebKitWebView::load-failed signal is emitted
before WebKitWebView::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.
WebKit2.WebView::load-failed
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.
WebKit2.WebView::load-failed-with-tls-errors
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().
since: 2.6
WebKit2.WebView::mouse-target-changed
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.
WebKit2.WebView::permission-request
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.
WebKit2.WebView::print
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.
WebKit2.WebView::query-permission-state
This signal allows the User-Agent to respond to permission requests for powerful features, as specified by the Permissions W3C Specification. You can reply to the query using webkit_permission_state_query_finish().
since: 2.40
WebKit2.WebView::ready-to-show
Emitted after WebKitWebView::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().
WebKit2.WebView::resource-load-started
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.
WebKit2.WebView::run-as-modal
Emitted after WebKitWebView::ready-to-show on the newly
created WebKitWebView when JavaScript code calls
WebKitWebView until the new dialog is closed.
WebKit2.WebView::run-color-chooser
This signal is emitted when the user interacts with a 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.
since: 2.8
WebKit2.WebView::run-file-chooser
This signal is emitted when the user interacts with a 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.
WebKit2.WebView::script-dialog
Emitted when JavaScript code calls 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.
WebKit2.WebView::show-notification
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.
since: 2.8
WebKit2.WebView::show-option-menu
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. 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.
since: 2.18
WebKit2.WebView::submit-form
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.
WebKit2.WebView::user-message-received
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().
since: 2.28
WebKit2.WebView::web-process-crashed
This signal is emitted when the web process crashes.
deprecated: 2.20
WebKit2.WebView::web-process-terminated
This signal is emitted when the web process terminates abnormally due
to reason.
since: 2.20
Signals inherited from GtkContainer (4)
GtkContainer::add
GtkContainer::check-resize
GtkContainer::remove
GtkContainer::set-focus-child
Signals inherited from GtkWidget (69)
GtkWidget::accel-closures-changed
GtkWidget::button-press-event
The ::button-press-event signal will be emitted when a button (typically from a mouse) is pressed.
GtkWidget::button-release-event
The ::button-release-event signal will be emitted when a button (typically from a mouse) is released.
GtkWidget::can-activate-accel
Determines whether an accelerator that activates the signal
identified by signal_id can currently be activated.
This signal is present to allow applications and derived
widgets to override the default GtkWidget handling
for determining whether an accelerator can be activated.
GtkWidget::child-notify
The ::child-notify signal is emitted for each [child property][child-properties] that has changed on an object. The signal’s detail holds the property name.
GtkWidget::composited-changed
The ::composited-changed signal is emitted when the composited
status of widgets screen changes.
See gdk_screen_is_composited().
GtkWidget::configure-event
The ::configure-event signal will be emitted when the size, position or
stacking of the widget‘s window has changed.
GtkWidget::damage-event
Emitted when a redirected window belonging to widget gets drawn into.
The region/area members of the event shows what area of the redirected
drawable was drawn into.
GtkWidget::delete-event
The ::delete-event signal is emitted if a user requests that
a toplevel window is closed. The default handler for this signal
destroys the window. Connecting gtk_widget_hide_on_delete() to
this signal will cause the window to be hidden instead, so that
it can later be shown again without reconstructing it.
GtkWidget::destroy
Signals that all holders of a reference to the widget should release the reference that they hold. May result in finalization of the widget if all references are released.
GtkWidget::destroy-event
The ::destroy-event signal is emitted when a GdkWindow is destroyed.
You rarely get this signal, because most widgets disconnect themselves
from their window before they destroy it, so no widget owns the
window at destroy time.
GtkWidget::direction-changed
The ::direction-changed signal is emitted when the text direction of a widget changes.
GtkWidget::drag-begin
The ::drag-begin signal is emitted on the drag source when a drag is started. A typical reason to connect to this signal is to set up a custom drag icon with e.g. gtk_drag_source_set_icon_pixbuf().
GtkWidget::drag-data-delete
The ::drag-data-delete signal is emitted on the drag source when a drag
with the action GDK_ACTION_MOVE is successfully completed. The signal
handler is responsible for deleting the data that has been dropped. What
“delete” means depends on the context of the drag operation.
GtkWidget::drag-data-get
The ::drag-data-get signal is emitted on the drag source when the drop
site requests the data which is dragged. It is the responsibility of
the signal handler to fill data with the data in the format which
is indicated by info. See gtk_selection_data_set() and gtk_selection_data_set_text().
GtkWidget::drag-data-received
The ::drag-data-received signal is emitted on the drop site when the
dragged data has been received. If the data was received in order to
determine whether the drop will be accepted, the handler is expected
to call gdk_drag_status() and not finish the drag.
If the data was received in response to a GtkWidget::drag-drop signal
(and this is the last target to be received), the handler for this
signal is expected to process the received data and then call
gtk_drag_finish(), setting the success parameter depending on
whether the data was processed successfully.
GtkWidget::drag-drop
The ::drag-drop signal is emitted on the drop site when the user drops
the data onto the widget. The signal handler must determine whether
the cursor position is in a drop zone or not. If it is not in a drop
zone, it returns FALSE and no further processing is necessary.
Otherwise, the handler returns TRUE. In this case, the handler must
ensure that gtk_drag_finish() is called to let the source know that
the drop is done. The call to gtk_drag_finish() can be done either
directly or in a GtkWidget::drag-data-received handler which gets
triggered by calling gtk_drag_get_data() to receive the data for one
or more of the supported targets.
GtkWidget::drag-end
The ::drag-end signal is emitted on the drag source when a drag is
finished. A typical reason to connect to this signal is to undo
things done in GtkWidget::drag-begin.
GtkWidget::drag-failed
The ::drag-failed signal is emitted on the drag source when a drag has
failed. The signal handler may hook custom code to handle a failed DnD
operation based on the type of error, it returns TRUE is the failure has
been already handled (not showing the default “drag operation failed”
animation), otherwise it returns FALSE.
GtkWidget::drag-leave
The ::drag-leave signal is emitted on the drop site when the cursor
leaves the widget. A typical reason to connect to this signal is to
undo things done in GtkWidget::drag-motion, e.g. undo highlighting
with gtk_drag_unhighlight().
GtkWidget::drag-motion
The ::drag-motion signal is emitted on the drop site when the user
moves the cursor over the widget during a drag. The signal handler
must determine whether the cursor position is in a drop zone or not.
If it is not in a drop zone, it returns FALSE and no further processing
is necessary. Otherwise, the handler returns TRUE. In this case, the
handler is responsible for providing the necessary information for
displaying feedback to the user, by calling gdk_drag_status().
GtkWidget::draw
This signal is emitted when a widget is supposed to render itself.
The widget‘s top left corner must be painted at the origin of
the passed in context and be sized to the values returned by
gtk_widget_get_allocated_width() and gtk_widget_get_allocated_height().
GtkWidget::enter-notify-event
The ::enter-notify-event will be emitted when the pointer enters
the widget‘s window.
GtkWidget::event
The GTK+ main loop will emit three signals for each GDK event delivered
to a widget: one generic ::event signal, another, more specific,
signal that matches the type of event delivered (e.g.
GtkWidget::key-press-event) and finally a generic
GtkWidget::event-after signal.
GtkWidget::event-after
After the emission of the GtkWidget::event signal and (optionally)
the second more specific signal, ::event-after will be emitted
regardless of the previous two signals handlers return values.
GtkWidget::focus
GtkWidget::focus-in-event
The ::focus-in-event signal will be emitted when the keyboard focus
enters the widget‘s window.
GtkWidget::focus-out-event
The ::focus-out-event signal will be emitted when the keyboard focus
leaves the widget‘s window.
GtkWidget::grab-broken-event
Emitted when a pointer or keyboard grab on a window belonging
to widget gets broken.
GtkWidget::grab-focus
GtkWidget::grab-notify
The ::grab-notify signal is emitted when a widget becomes shadowed by a GTK+ grab (not a pointer or keyboard grab) on another widget, or when it becomes unshadowed due to a grab being removed.
GtkWidget::hide
The ::hide signal is emitted when widget is hidden, for example with gtk_widget_hide().
GtkWidget::hierarchy-changed
The ::hierarchy-changed signal is emitted when the
anchored state of a widget changes. A widget is
“anchored” when its toplevel
ancestor is a GtkWindow. This signal is emitted when
a widget changes from un-anchored to anchored or vice-versa.
GtkWidget::key-press-event
The ::key-press-event signal is emitted when a key is pressed. The signal emission will reoccur at the key-repeat rate when the key is kept pressed.
GtkWidget::key-release-event
The ::key-release-event signal is emitted when a key is released.
GtkWidget::keynav-failed
Gets emitted if keyboard navigation fails.
See gtk_widget_keynav_failed() for details.
GtkWidget::leave-notify-event
The ::leave-notify-event will be emitted when the pointer leaves
the widget‘s window.
GtkWidget::map
The ::map signal is emitted when widget is going to be mapped, that is
when the widget is visible (which is controlled with
gtk_widget_set_visible()) and all its parents up to the toplevel widget
are also visible. Once the map has occurred, GtkWidget::map-event will
be emitted.
GtkWidget::map-event
The ::map-event signal will be emitted when the widget‘s window is
mapped. A window is mapped when it becomes visible on the screen.
GtkWidget::mnemonic-activate
The default handler for this signal activates widget if group_cycling
is FALSE, or just makes widget grab focus if group_cycling is TRUE.
GtkWidget::motion-notify-event
The ::motion-notify-event signal is emitted when the pointer moves
over the widget’s GdkWindow.
GtkWidget::move-focus
GtkWidget::parent-set
The ::parent-set signal is emitted when a new parent has been set on a widget.
GtkWidget::popup-menu
This signal gets emitted whenever a widget should pop up a context
menu. This usually happens through the standard key binding mechanism;
by pressing a certain key while a widget is focused, the user can cause
the widget to pop up a menu. For example, the GtkEntry widget creates
a menu with clipboard commands. See the
[Popup Menu Migration Checklist][checklist-popup-menu]
for an example of how to use this signal.
GtkWidget::property-notify-event
The ::property-notify-event signal will be emitted when a property on
the widget‘s window has been changed or deleted.
GtkWidget::proximity-in-event
To receive this signal the GdkWindow associated to the widget needs
to enable the #GDK_PROXIMITY_IN_MASK mask.
GtkWidget::proximity-out-event
To receive this signal the GdkWindow associated to the widget needs
to enable the #GDK_PROXIMITY_OUT_MASK mask.
GtkWidget::query-tooltip
Emitted when GtkWidget:has-tooltip is TRUE and the hover timeout
has expired with the cursor hovering “above” widget; or emitted when widget got
focus in keyboard mode.
GtkWidget::realize
The ::realize signal is emitted when widget is associated with a
GdkWindow, which means that gtk_widget_realize() has been called or the
widget has been mapped (that is, it is going to be drawn).
GtkWidget::screen-changed
The ::screen-changed signal gets emitted when the screen of a widget has changed.
GtkWidget::scroll-event
The ::scroll-event signal is emitted when a button in the 4 to 7 range is pressed. Wheel mice are usually configured to generate button press events for buttons 4 and 5 when the wheel is turned.
GtkWidget::selection-clear-event
The ::selection-clear-event signal will be emitted when the
the widget‘s window has lost ownership of a selection.
GtkWidget::selection-get
GtkWidget::selection-notify-event
GtkWidget::selection-received
GtkWidget::selection-request-event
The ::selection-request-event signal will be emitted when
another client requests ownership of the selection owned by
the widget‘s window.
GtkWidget::show
The ::show signal is emitted when widget is shown, for example with gtk_widget_show().
GtkWidget::show-help
GtkWidget::size-allocate
GtkWidget::state-changed
The ::state-changed signal is emitted when the widget state changes. See gtk_widget_get_state().
GtkWidget::state-flags-changed
The ::state-flags-changed signal is emitted when the widget state changes, see gtk_widget_get_state_flags().
GtkWidget::style-set
The ::style-set signal is emitted when a new style has been set
on a widget. Note that style-modifying functions like
gtk_widget_modify_base() also cause this signal to be emitted.
GtkWidget::style-updated
The ::style-updated signal is a convenience signal that is emitted when the
GtkStyleContext::changed signal is emitted on the widget‘s associated
GtkStyleContext as returned by gtk_widget_get_style_context().
GtkWidget::touch-event
GtkWidget::unmap
The ::unmap signal is emitted when widget is going to be unmapped, which
means that either it or any of its parents up to the toplevel widget have
been set as hidden.
GtkWidget::unmap-event
The ::unmap-event signal will be emitted when the widget‘s window is
unmapped. A window is unmapped when it becomes invisible on the screen.
GtkWidget::unrealize
The ::unrealize signal is emitted when the GdkWindow associated with
widget is destroyed, which means that gtk_widget_unrealize() has been
called or the widget has been unmapped (that is, it is going to be hidden).
GtkWidget::visibility-notify-event
The ::visibility-notify-event will be emitted when the widget‘s
window is obscured or unobscured.
GtkWidget::window-state-event
The ::window-state-event will be emitted when the state of the
toplevel window associated to the widget changes.
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
