// This demo uses the Views Framework in CEF to create a child window with a
// web browser.
// CEF4Delphi has several components to facilitate the creation of several views
// and this demo uses these :
// TCEFWindowComponent : Has a ICefWindow and a ICefWindowDelegate to call
// the methods of a "CefWindow" and the events from the "CefWindowDelegate".
// Read the linked documents bellow for more details about them.
// TCEFBrowserViewComponent : Has a ICefBrowserView and a ICefBrowserViewDelegate
// to call the methods of a "CefBrowserView" and the events from the
// "CefBrowserViewDelegate".
// TChromium : Is used to create the browser and to handle all its events.
// All the views have a hierarchy and they inherit methods or events from their
// parents. See the diagram in the uCEFTypes.pas file (line 2900 aprox.)
// This demo creates a window when the user clicks on the "Open" button.
// Most of the methods in the Views Framework must be used in the CEF UI thread
// but most of the procedures used to create the CEF4Delphi components create a
// task if they are called in a different thread. The rest of the methods *MUST*
// be called in the CEF UI thread or they won't work.
// TCEFWindowComponent.CreateTopLevelWindow triggers the
// TCEFWindowComponent.OnWindowCreated event which is executed in the CEF UI
// thread and you can use it to create the child views in the window, in this
// case a browser view.
// TCEFWindowComponent.OnGetPreferredSize will alse be triggered when you create
// the window to get the window size in DIPs.
