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.
