//
//  G4UIQt : class to handle a Qt interactive session.
// G4UIQt is the Qt version of G4UIterminal.
//
//  A command box is at disposal for entering/recalling Geant4 commands.
//  A menubar could be customized through the AddMenu, AddButton, AddIcon methods.
//  Note that there are corresponding Geant4 commands to add a 
// menus 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.
