### Class

# WebKit WebView

#### Description [src]

    class WebKit.WebView : WebKit.WebViewBase
      implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget {
      WebKitWebViewPrivate* priv
    }

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`.

#### 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.

#### Signals

###### WebKit.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

###### WebKit.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.

###### WebKit.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. To customize the proposed menu you can use webkit_context_menu_prepend(), `webkit_context_menu_append()` or `webkit_context_menu_insert()` to add new `WebKitContextMenuItem`s 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. .

###### WebKit.WebView::context-menu-dismissed

Emitted after `WebKitWebView::context-menu` signal, if the context menu is shown, to notify that the context menu is dismissed.

###### WebKit.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`.

###### WebKit.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:.

###### WebKit.WebView::enter-fullscreen

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).

###### WebKit.WebView::insecure-content-detected

Prior to 2.46, this signal was emitted when insecure content was loaded in a secure content. Since 2.46, this signal is generally no longer emitted.

deprecated: 2.46

###### WebKit.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.

###### WebKit.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.

###### WebKit.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.

###### WebKit.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

###### WebKit.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`.

###### WebKit.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.

###### WebKit.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.

###### WebKit.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

###### WebKit.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().

###### WebKit.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`.

###### WebKit.WebView::run-as-modal

Emitted after `WebKitWebView::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.

###### WebKit.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

###### WebKit.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.

###### WebKit.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. .

###### WebKit.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

###### WebKit.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. To handle this signal asynchronously you should keep a ref of the `menu`.

since: 2.18

###### WebKit.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.

###### WebKit.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

###### WebKit.WebView::web-process-terminated

This signal is emitted when the web process terminates abnormally due to `reason`.

since: 2.20

##### Signals inherited from GtkWidget (13)

###### GtkWidget::destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

###### GtkWidget::direction-changed

Emitted when the text direction of a widget changes.

###### GtkWidget::hide

Emitted when `widget` is hidden.

###### GtkWidget::keynav-failed

Emitted if keyboard navigation fails.

###### GtkWidget::map

Emitted when `widget` is going to be mapped.

###### GtkWidget::mnemonic-activate

Emitted when a widget is activated via a mnemonic.

###### GtkWidget::move-focus

Emitted when the focus is moved.

###### GtkWidget::query-tooltip

Emitted when the widget’s tooltip is about to be shown.

###### GtkWidget::realize

Emitted when `widget` is associated with a `GdkSurface`.

###### GtkWidget::show

Emitted when `widget` is shown.

###### GtkWidget::state-flags-changed

Emitted when the widget state changes.

###### GtkWidget::unmap

Emitted when `widget` is going to be unmapped.

###### GtkWidget::unrealize

Emitted when the `GdkSurface` associated with `widget` is destroyed.

##### 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.
