26//
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.
