WebKit2.WebView (original) (raw)

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.

Constructors

Instance methods

webkit_web_view_call_async_javascript_function

Asynchronously call body with arguments in the script world with name world_name of the main frame current context in web_view. The arguments values must be one of the following types, or contain only the following GVariant types: number, string and dictionary. The result of the operation can be a Promise that will be properly passed to the callback. If world_name is NULL, the default world is used. Any value that is not NULL is a distin ct world. The source_uri will be shown in exceptions and doesn’t affect the behavior of the script. When not provided, the document URL is used.

since: 2.40

webkit_web_view_evaluate_javascript

Asynchronously evaluate script in the script world with name world_name of the main frame current context in web_view. If world_name is NULL, the default world is used. Any value that is not NULL is a distinct world. The source_uri will be shown in exceptions and doesn’t affect the behavior of the script. When not provided, the document URL is used.

since: 2.40

webkit_web_view_run_async_javascript_function_in_world

Asynchronously run body in the script world with name world_name of the current page context inweb_view. If WebKitSettings:enable-javascript is FALSE, this method will do nothing. This APIdiffers from webkit_web_view_run_javascript_in_world() in that the JavaScript function can return a Promise and its result will be properly passed to the callback.

deprecated: 2.40 since: 2.38

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-viewsignal request. If the new WebView was added to a new tab of current browsing context windowWEBKIT_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: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-viewsignal 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 WebKitWebsiteDataManagerits 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 ephemeralWebKitWebView and it can’t be changed. The ephemeral WebKitWebsiteDataManagercreated for the WebKitWebView will inherit the network settings from theWebKitWebContext‘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 WebKitWebContextwill 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 becomesTRUE as soon as a new load operation is requested and before theWebKitWebView::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 beforeWebKitWebView::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.

since: 2.8

WebKit2.WebView:microphone-capture-state

Capture state of the microphone device. Whenever the user grants a media-request sent by the web page, requesting audio capture capabilities (navigator.mediaDevices.getUserMedia({audio: true})) this property will be set to WEBKIT_MEDIA_CAPTURE_STATE_ACTIVE.

since: 2.34

WebKit2.WebView:related-view

The related WebKitWebView used when creating the view to share the same web process and network session. This property is not readable because the related web view is only valid during the object construction.

since: 2.4

WebKit2.WebView:title

The main frame document title of this WebKitWebView. If the title has not been received yet, it will be NULL.

WebKit2.WebView:uri

The current active URI of the WebKitWebView. See webkit_web_view_get_uri() for more details.

Signals

WebKit2.WebView::authenticate

This signal is emitted when the user is challenged with HTTPauthentication. 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 theWebKitAuthenticationRequest 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 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.

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 newWebKitContextMenuItems 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.

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 thedecision 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 callselement.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).

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 theWebKitWebView::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 withWEBKIT_LOAD_FINISHED. If a redirection is received from the server, this signal is emitted with WEBKIT_LOAD_REDIRECTED after the initial emission withWEBKIT_LOAD_STARTED and before WEBKIT_LOAD_COMMITTED. When the page content starts arriving the signal is emitted withWEBKIT_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 pageload_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 withWEBKIT_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 certificateand 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 thehit_test_result argument. The modifiers argument is a bitmask ofGdkModifierType 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() andwebkit_print_operation_set_page_setup() and then return FALSE to propagate the event so that the print dialog is shown.

WebKit2.WebView::ready-to-show

Emitted after WebKitWebView::create on the newly created WebKitWebViewwhen 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 WebKitWindowPropertiesof 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.

Emitted after WebKitWebView::ready-to-show on the newly created WebKitWebView when JavaScript code callswindow.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 parentWebKitWebView 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 requestargument.

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 requestargument.

WebKit2.WebView::script-dialog

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.

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

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 theWebKitWebView 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 requestargument 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 theWebKitWebPage corresponding to web_view. You can reply to the message using webkit_user_message_send_reply().

since: 2.28

Signals inherited from GtkWidget (69)

GtkWidget::accel-closures-changed

No description available.

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 bygtk_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 genericGtkWidget::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

No description available.

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

No description available.

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_cyclingis 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

No description available.

GtkWidget::parent-set

The ::parent-set signal is emitted when a new parent has been set on a widget.

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.

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 aGdkWindow, 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::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 likegtk_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 theGtkStyleContext::changed signal is emitted on the widget‘s associatedGtkStyleContext as returned by gtk_widget_get_style_context().

GtkWidget::touch-event

No description available.

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
