Class Description

                                                                      
 TApplication                                                         
                                                                      
 This class creates the ROOT Application Environment that interfaces  
 to the windowing system eventloop and eventhandlers.                 
 This class must be instantiated exactly once in any given            
 application. Normally the specific application class inherits from   
 TApplication (see TRint).                                            
                                                                      

 Create an application environment. The application environment
 provides an interface to the graphics system and eventloop
 (be it X, Windoze, MacOS or BeOS). After creating the application
 object start the eventloop by calling its Run() method. The command
 line options recogized by TApplication are described in the GetOptions()
 method. The recognized options are removed from the argument array.
 The original list of argument options can be retrieved via the Argc()
 and Argv() methods. The "options" and "numOptions" arguments are
 not used. The appClassName "proofserv" is reserved for the PROOF system.

 TApplication dtor.

 Clear list containing macro files passed as program arguments.
 This method is called from TRint::Run() to ensure that the macro
 files are only executed the first time Run() is called.

 Get and handle command line options. Arguments handled are removed
 from the argument array. The following arguments are handled:
    -? : help
    -h : help
    -b : run in batch mode without graphics
    -n : do not execute logon and logoff macros as specified in .rootrc
    -q : exit after processing command line macro files
    -l : do not show splash screen
 The last three options are only relevant in conjunction with TRint.

 Handle idle timeout. When this timer expires the registered idle command
 will be executed by this routine.

 Print help on interpreter.

 Initialize colors used by the TCanvas based graphics (via TColor objects).
 This method should be called before the ApplicationImp is created (which
 initializes the GUI colors).

 Load shared libs neccesary for graphics. These libraries are only
 loaded when gROOT->IsBatch() is kFALSE.

 Process a single command line, either a C++ statement or an interpreter
 command starting with a ".".

 Process a file containing a C++ macro.

 Main application eventloop. Calls system dependent eventloop via gSystem.

 Set the command to be executed after the system has been idle for
 idleTimeInSec seconds. Normally called via TROOT::Idle(...).

 Remove idle timer. Normally called via TROOT::Idle(0).

 Call when system starts idleing.

 Call when system stops idleing.

 Terminate the application by call TSystem::Exit() unless application has
 been told to return from Run(), by a call to SetReturnFromRun().

 Static function used to create a default application environment.
