//  G4UIXm : class to handle a Motif interactive session.
// G4UIXm is the Motif 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

//    /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.
