#ifdef q_os_macvoid Mainwindow::initmenu () {qmenubar* MBar = MenuBar ();    qmenu* mApp = new Qmenu (tr ("App"), this);    qmenu* mfile = new Qmenu (tr ("&file"), this);    Mbar->addmenu (MAPP);    Mbar->addmenu (Mfile);    /** in Mac,we should to set action role */qaction* actabout = new Qaction (tr ("&about"), this);    Actabout->setmenurole (Qaction::aboutrole);    qaction* Actsetapp = new Qaction (tr ("&preference ..."), this);    Actsetapp->setmenurole (qaction::P referencesrole);    Mapp->addaction (actabout);    Mapp->addaction (Actsetapp);    qaction* Actopen = new Qaction (tr ("&open Video Files ..."), this);    Mfile->addaction (Actopen);    Connect (Actopen,&qaction::triggered,_player,&player::stopen); Connect (ACTSETAPP,&QACTION::TRIGGERED,THIS,&MAINWINDOW::STSHOWSETDLG);}    #elsevoid Mainwindow::initmenu () {qmenubar* MBar = MenuBar ();    qmenu* mfile = new Qmenu (tr ("&file"), this); qmenu* MSet = new Qmenu (tr ("&setting"), thIS);    qmenu* mabout = new Qmenu (tr ("&about"), this);    qaction* Actopen = new Qaction (tr ("&open Video Files ..."), this);    qaction* actexit = new Qaction (tr ("&exit out"), this);    Mfile->addaction (Actopen);    Mfile->addseparator ();    Mfile->addaction (Actexit);    qaction* Actsetapp = new Qaction (tr ("&setting App ..."), this);    Mset->addaction (Actsetapp);    Mbar->addmenu (Mfile);    Mbar->addmenu (MSet);    Mbar->addmenu (mabout);    Connect (Actopen,&qaction::triggered,_player,&player::stopen);    Connect (actexit,&qaction::triggered,this,[=] () {close ();}); Connect (ACTSETAPP,&QACTION::TRIGGERED,THIS,&MAINWINDOW::STSHOWSETDLG);} #endif
