15 ROOT top level object description.
16 
17 The TROOT object is the entry point to the ROOT system.
18 The single instance of TROOT is accessible via the global gROOT.
19 Using the gROOT pointer one has access to basically every object
20 created in a ROOT based program. The TROOT object is essentially a
21 container of several lists pointing to the main ROOT objects.
22 
23 The following lists are accessible from gROOT object:
24 
25 ~~~ {.cpp}
26  gROOT->GetListOfClasses
27  gROOT->GetListOfColors
28  gROOT->GetListOfTypes
29  gROOT->GetListOfGlobals
30  gROOT->GetListOfGlobalFunctions
31  gROOT->GetListOfFiles
32  gROOT->GetListOfMappedFiles
33  gROOT->GetListOfSockets
34  gROOT->GetListOfSecContexts
35  gROOT->GetListOfCanvases
36  gROOT->GetListOfStyles
37  gROOT->GetListOfFunctions
38  gROOT->GetListOfSpecials (for example graphical cuts)
39  gROOT->GetListOfGeometries
40  gROOT->GetListOfBrowsers
41  gROOT->GetListOfCleanups
42  gROOT->GetListOfMessageHandlers
43 ~~~
44 
45 The TROOT class provides also many useful services:
46  - Get pointer to an object in any of the lists above
47  - Time utilities TROOT::Time
48 
49 The ROOT object must be created as a static object. An example
50 of a main program creating an interactive version is shown below:
51 
52 ### Example of a main program
53 
54 ~~~ {.cpp}
55  #include "TRint.h"
56 
57  int main(int argc, char **argv)
58  {
59  TRint *theApp = new TRint("ROOT example", &argc, argv);
60 
61  // Init Intrinsics, build all windows, and enter event loop
62  theApp->Run();
63 
64  return(0);
65  }
