// File Overview....
// This is the class which implements all the interfaces
// required(and optional) by the mozilla embeddable browser engine
//
// Note that this obj gets passed in the IBrowserFrameGlue* using the
// Init() method. Many of the interface implementations use this
// to get the actual task done. Ex: to update the status bar
//
// Look at the INTERFACE_MAP_ENTRY's below for the list of
// the currently implemented interfaces
//
// This file currently has the implementation for all the interfaces
// which are required of an app embedding Gecko
// Implementation of other optional interfaces are in separate files
// to avoid cluttering this one and to demonstrate other embedding
// principles. For example, nsIPrompt is implemented in a separate DLL.
//
// nsIWebBrowserChrome - This is a required interface to be implemented
// by embeddors
//
// nsIEmbeddingSiteWindow - This is a required interface to be implemented
// by embedders
// - SetTitle() gets called after a document
// load giving us the chance to update our
// titlebar
//
// Some points to note...
//
// nsIWebBrowserChrome interface's SetStatus() gets called when a user
// mouses over the links on a page
//
// nsIWebProgressListener interface's OnStatusChange() gets called
// to indicate progress when a page is being loaded
//
// Next suggested file(s) to look at :
// Any of the BrowserImpl*.cpp files for other interface
// implementation details
//
