41 // The typical MFC View, toolbar, statusbar creation done
42 // in CBrowserFrame::OnCreate()
44 // Code to update the Status/Tool bars in response to the
45 // Web page loading progress(called from methods in CBrowserImpl)
47 // SetupFrameChrome() determines what, if any, UI elements this Frame
48 // will sport based on the current "chromeMask"
50 // Also take a look at OnClose() which gets used when you close a browser
51 // window. This needs to be overrided mainly to handle supporting multiple
52 // browser frame windows via the "New Browser Window" menu item
53 // Without this being overridden the MFC framework handles the OnClose and
54 // shutsdown the complete application when a frame window is closed.
55 // In our case, we want the app to shutdown when the File/Exit menu is chosen
57 // Another key functionality this object implements is the IBrowserFrameGlue
58 // interface - that's the interface the Gecko embedding interfaces call
59 // upong to update the status bar etc.
60 // (Take a look at IBrowserFrameGlue.h for the interface definition and
61 // the BrowserFrm.h to see how we implement this interface - as a nested
63 // We pass this Glue object pointer to the CBrowserView object via the
64 // SetBrowserFrameGlue() method. The CBrowserView passes this on to the
65 // embedding interface implementaion
67 // Please note the use of the macro METHOD_PROLOGUE in the implementation
68 // of the nested BrowserFrameGlue object. Essentially what this macro does
69 // is to get you access to the outer (or the object which is containing the
70 // nested object) object via the pThis pointer.
