TApplication Class Reference

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() [3/3]

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.

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.

◆ ProcessLine()

virtual Long_t TApplication::ProcessLine ( const char *  line,
Bool_t  sync = kFALSE,
Int_t error = 0 
)
virtual

Reimplemented in TApplicationServer, and TApplicationRemote.

◆ ProcessRemote()

Long_t TApplication::ProcessRemote ( const char *  line,
Int_t error = 0 
)
protectedvirtual

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

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

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.

Reimplemented in TRint.
