Signal
WebKit2WebView::permission-request
Declaration
gboolean
permission_request (
WebKitWebView* self,
WebKit2PermissionRequest* 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.
