onLoadChanged
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.
You can handle this signal and use a switch to track any ongoing load operation.
