The TQRootSlot singleton class introduces the global SLOT to invoke
the ROOT command line from the GUI signals
Optionally one can execute TApplication::Terminate method directly
It provides a Qt slot to attach the the CINT C++ interpreter
to any Qt signal
To execute any C++ statement from the GUI oen should connect
his/her Qt signal with the Qt slot of the global instance of this class
connect(GUI object, SIGNAL(const char *editedLine),TQtRootSlot::CintSlot(),SLOT(ProcessLine(const char*)))
To terminate the ROOT from QUI element connect the signal with the Terminate slot.
For example to terminate ROOT and Qt smootly do
connect(qApp,SIGNAL(lastWindowClosed()),TQtRootSlot::CintSlot(),SLOT(TerminateAndQuit())
