Description: Reference for signal WebKit.WebView::permission-request

### Signal

# WebKit WebView::permission-request

#### Declaration

    gboolean
    permission_request (
      WebKitWebView* self,
      WebKitPermissionRequest* request,
      gpointer user_data
    )

#### Description [src]

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.

If the signal is not handled, the `request` will be completed automatically by the specific `WebKitPermissionRequest` that could allow or deny it. Check the documentation of classes implementing `WebKitPermissionRequest` interface to know their default action.

Default handler: The default handler is called after the handlers added via `g_signal_connect()`.

#### Parameters

`request`

  Type: `WebKitPermissionRequest`

  The `WebKitPermissionRequest`.

  The data is owned by the caller of the function.

#### Return value

Type: `gboolean`

`TRUE` to stop other handlers from being invoked for the event. `FALSE` to propagate the event further.
