//
// Class description :
//
// G4UIWin32 is a class to handle a Windows interactive session.
// It is the Windows version of G4UIterminal.
//
//  A command box is at disposal for entering/recalling Geant4 commands.
//  A menubar could be customized through the AddMenu, AddButton methods.
//  Note that there are corresponding Geant4 commands to add a 
//  menu in the menubar and add buttons in a menu.
//  Ex : 
//    /gui/addMenu   test Test
//    /gui/addButton test Init /run/initialize
//    /gui/addButton test "Set gun" "/control/execute gun.g4m"
//    /gui/addButton test "Run one event" "/run/beamOn 1"
//
// Command completion, by typing "tab" key, is available on the
// command line.
