// Please, read the code comments in the JSExtension demo (uJSExtension.pas) before using this demo!
// This demo is almost identical to JSExtension but it uses a slightly easier
// way to register JavaScript extensions inherited from the DCEF3 project.
// Instead of creating a custom class inherited from TCefv8HandlerOwn and calling the
// CefRegisterExtension function, this demo uses the TCefRTTIExtension.Register
// class procedure to register the TTestExtension class, which is a custom Delphi
// class with 2 class procedures.
// TCefRTTIExtension uses the RTTI from the TTestExtension class to generate the
// JS code and the ICefv8Handler parameters needed by CefRegisterExtension.
// You still need to call TCefRTTIExtension.Register in the GlobalCEFApp.OnWebKitInitialized event
// and use process messages to send information between processes.
// TTestExtension can send information back to the browser with a process message.
// The TTestExtension.mouseover function do this by calling
// TCefv8ContextRef.Current.Browser.MainFrame.SendProcessMessage(PID_BROWSER, msg);
// That message is received in the TChromium.OnProcessMessageReceived event.
// Destruction steps
// =================
// 1. FormCloseQuery sets CanClose to FALSE calls TChromium.CloseBrowser which triggers the TChromium.OnClose event.
// 2. TChromium.OnClose sends a CEFBROWSER_DESTROY message to destroy CEFWindowParent1 in the main thread, which triggers the TChromium.OnBeforeClose event.
// 3. TChromium.OnBeforeClose calls TCEFSentinel.Start, which will trigger TCEFSentinel.OnClose when the renderer processes are closed.
// 4. TCEFSentinel.OnClose sets FCanClose := True and sends WM_CLOSE to the form.
