WebView.connectLoadChanged

Connect to LoadChanged signal.

Emitted when a load operation in web_view changes. The signal is always emitted with [webkit.types.LoadEvent.Started] when a new load request is made and [webkit.types.LoadEvent.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.types.LoadEvent.Finished]. If a redirection is received from the server, this signal is emitted with [webkit.types.LoadEvent.Redirected] after the initial emission with [webkit.types.LoadEvent.Started] and before [webkit.types.LoadEvent.Committed]. When the page content starts arriving the signal is emitted with [webkit.types.LoadEvent.Committed] event.

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