onPermissionRequest

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.
