## Implemented Interfaces

WebKitWebView implements AtkImplementorIface and GtkBuildable.

## Description

WebKitWebView is the central class of the WebKit2GTK+ API. 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 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 and WebKitSettings as `web_view` .

#### Parameters

web_view | the related WebKitWebView |

#### Returns

The newly created WebKitWebView widget.

### webkit_web_view_load_uri ()

    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.

#### 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`. | [allow-none]

### webkit_web_view_load_alternate_html ()

                                         const gchar *content_uri,
                                         const gchar *base_uri);

Load the given `content` 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, the the back-forward list is maintained appropriately. For everything else this method works the same way as `webkit_web_view_load_html()`.

#### Parameters

web_view | a WebKitWebView |
content | the new content to display as the main page of the `web_view` |
content_uri | the URI for the alternate page content |
base_uri | the base URI for relative locations or `NULL`. | [allow-none]

### webkit_web_view_get_uri ()

    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:

1. When nothing has been loaded yet on `web_view` the active URI is `NULL`.

2. 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.

WEBKIT_POLICY_DECISION_TYPE_NAVIGATION_ACTION | This type of policy decision is requested when WebKit is about to navigate to a new page in either the main frame or a subframe. Acceptable policy decisions are either `webkit_policy_decision_use()` or `webkit_policy_decision_ignore()`. This type of policy decision is always a WebKitNavigationPolicyDecision. |
WEBKIT_POLICY_DECISION_TYPE_NEW_WINDOW_ACTION | This type of policy decision is requested when WebKit is about to create a new window. Acceptable policy decisions are either `webkit_policy_decision_use()` or `webkit_policy_decision_ignore()`. This type of policy decision is always a WebKitNavigationPolicyDecision. These decisions are useful for implementing special actions for new windows, such as forcing the new window to open in a tab when a keyboard modifier is active or handling a special target attribute on <a> elements. |
WEBKIT_POLICY_DECISION_TYPE_RESPONSE | This type of decision is used when WebKit has received a response for a network resource and is about to start the load. Note that these resources include all subresources of a page such as images and stylesheets as well as main documents. Appropriate policy responses to this decision are `webkit_policy_decision_use()`, `webkit_policy_decision_ignore()`, or `webkit_policy_decision_download()`. This type of policy decision is always a WebKitResponsePolicyDecision. This decision is useful for forcing some types of resources to be downloaded rather than rendered in the WebView or to block the transfer of resources entirely. |

## 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 *webView,
                   gpointer       user_data)

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

#### Parameters

webView | 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)

Emmited 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.

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

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 `“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.

When using `WEBKIT_PROCESS_MODEL_MULTIPLE_SECONDARY_PROCESSES` process model, the new WebKitWebView should be related to `web_view` to share the same web process, 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. |

#### Returns

a newly allocated WebKitWebView widget or `NULL` to propagate the event further.

### 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:

                      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.

### 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 the 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,
                   gchar          *failing_uri,
                   gpointer        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.

    user_function (WebKitWebView       *web_view,
                   gchar               *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` |
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.

                   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 | user data set when the signal handler was connected. |

                   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:

    static gboolean permission_request_cb (WebKitWebView *web_view,
                                           WebKitPermissionRequest *request,
                                           GtkWindow *parent_window)
    {
        GtkWidget *dialog = gtk_message_dialog_new (parent_window,
                                                    GTK_DIALOG_MODAL,
                                                    GTK_MESSAGE_QUESTION,
                                                    GTK_BUTTONS_YES_NO,
                                                    "Allow Permission Request?");
        gtk_widget_show (dialog);
        gint result = gtk_dialog_run (GTK_DIALOG (dialog));

        switch (result) {
        case GTK_RESPONSE_YES:
            webkit_permission_request_allow (request);
            break;
        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.

By default, if the signal is not handled, `webkit_permission_request_deny()` will be called over the WebKitPermissionRequest.

#### 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

web_view | 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.

### The `“ready-to-show”` signal

    void
    user_function (WebKitWebView *web_view,
                   gpointer       user_data)

Emitted after “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()`.

#### 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 `“resource-load-started”` signal

    void
    user_function (WebKitWebView     *web_view,
                   WebKitWebResource *resource,
                   WebKitURIRequest  *request,
                   gpointer           user_data)

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` .

#### Parameters

web_view | the WebKitWebView on which the signal is emitted |
resource | a WebKitWebResource |
request | a WebKitURIRequest |
user_data | user data set when the signal handler was connected. |

### The `“run-as-modal”` signal

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

#### Parameters

web_view | the WebKitWebView on which the signal is emitted |
user_data | user data set when the signal handler was connected. |

### The `“run-file-chooser”` signal

    gboolean
    user_function (WebKitWebView            *web_view,
                   WebKitFileChooserRequest *request,
                   gpointer                  user_data)

This signal is emitted when the user interacts with a <input type='file' /> 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.

The default signal handler will asynchronously run a regular GtkFileChooserDialog for the user to interact with.

#### Parameters

web_view | the WebKitWebView on which the signal is emitted |
request | a WebKitFileChooserRequest |
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 `“script-dialog”` signal

    gboolean
    user_function (WebKitWebView      *web_view,
                   WebKitScriptDialog *dialog,
                   gpointer            user_data)

Emitted when JavaScript code calls `window.alert`, `window.confirm` or `window.prompt`. 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.

#### Parameters

web_view | the WebKitWebView on which the signal is emitted |
dialog | the WebKitScriptDialog to show |
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 `“web-process-crashed”` signal

    gboolean
    user_function (WebKitWebView *web_view,
                   gpointer       user_data)

This signal is emitted when the web process crashes.

#### Parameters

web_view | the WebKitWebView |
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.
