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).

TApplication::TApplication	(	const char *	appClassName,
		Int_t *	argc,
		char **	argv,
		void *	options = `0`,
		Int_t	numOptions = `0`
	)

Create an application environment.

The application environment provides an interface to the graphics system and eventloop (be it X, Windows, MacOS or BeOS). After creating the application object start the eventloop by calling its Run() method. The command line options recognized 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 appClassName "proofserv" is reserved for the PROOF system. The "options" and "numOptions" arguments are not used, except if you want to by-pass the argv processing by GetOptions() in which case you should specify numOptions<0. All options will still be available via the Argv() method for later use.

void TApplication::GetOptions	(	Int_t *	argc,
		char **	argv
	)

virtual

Get and handle command line options.

Arguments handled are removed from the argument array. The following arguments are handled:

b : run in batch mode without graphics
x : exit on exception
e expression: request execution of the given C++ expression.
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. The following help and info arguments are supported:

? : print usage
h : print usage
-help : print usage
config : print ./configure options
memstat : run with memory usage monitoring

In addition to the above options the arguments that are not options, i.e. they don't start with - or + are treated as follows (and also removed from the argument array):

<dir> is considered the desired working directory and available via WorkingDirectory(), if more than one dir is specified the first one will prevail
<file> if the file exists its added to the InputFiles() list
<file>.root are considered ROOT files and added to the InputFiles() list, the file may be a remote file url
<macro>.C are considered ROOT macros and also added to the InputFiles() list

In TRint we set the working directory to the <dir>, the ROOT files are connected, and the macros are executed. If your main TApplication is not TRint you have to decide yourself what to do with these options. All specified arguments (also the ones removed) can always be retrieved via the TApplication::Argv() method.

	)

staticprotected

Parse the content of a line starting with ".R" (already stripped-off) The format is

[user@]host[:dir] [-l user] [-d dbg] [script]

The variable 'dir' is the remote directory to be used as working dir.

The username can be specified in two ways, "-l" having the priority (as in ssh). A 'dbg' value > 0 gives increasing verbosity. The last argument 'script' allows to specify an alternative script to be executed remotely to startup the session.
