27	// MStatusDisplay
28	//
29	// This status display can be used (and is used) to display results in
30	// a tabbed window. The window can be written to and read from a root file
31	// (see Read and Write) or printed as a postscript file (see SaveAsPS).
32	//
33	// To write gif files of C-Macros use SaveAsGif()/SaveAsPNG() or SaveAsC().
34	// Direct printing to the default printer (via lpr) can be done by
35	// PrintPS().
36	//
37	// It has also to half status lines which can be used to display the status
38	// or something going on. Together with the status lines it has a progress
39	// bar which can display the progress of a job or loop.
40	// Access the progress bar by GetProgressBar()
41	//
42	// To add a new tab and get a pointer to the newly created TCanvas
43	// use AddTab.
44	//
45	// If you have a MStatusDisplay and you are not sure whether it was
46	// destroyed by the user meanwhile use:
47	// gROOT->GetListOfSpecials()->FindObject(pointer);
48	// Each MStatusDisplay is added to list list by its constructor and
49	// removed from the list by the destructor.
50	//
51	// You can redirect an output to a MLog-logstream by calling SetLogStream().
52	// To disable redirction call SetLogStream(NULL)
53	//
54	// Because updates to the tabs are only done/displayed if a tab is active
55	// using the gui doesn't make things slower (<1%) if the first (legend
56	// tab) is displayed. This gives you the possibility to look into
57	// the current progress of a loop without loosing more time than the
58	// single update of the tab.
