浅谈：QT       += widgets

1.当出现一下的问题的时候，在.pro文件中加上 QT += widgets，试试看。

QObject::connect: No such slot QToolBox::showChatWidget1() in ..\qq_test_new\drawer.cpp:17

QObject::connect: No such slot QToolBox::showChatWidget2() in ..\qq_test_new\drawer.cpp:25

QObject::connect: No such slot QToolBox::showChatWidget3() in ..\qq_test_new\drawer.cpp:33

QObject::connect: No such slot QToolBox::showChatWidget4() in ..\qq_test_new\drawer.cpp:41

QObject::connect: No such slot QToolBox::showChatWidget5() in ..\qq_test_new\drawer.cpp:49

QObject::connect: No such slot QToolBox::showChatWidget6() in ..\qq_test_new\drawer.cpp:57

QObject::connect: No such slot QToolBox::showChatWidget7() in ..\qq_test_new\drawer.cpp:65

QObject::connect: No such slot QToolBox::showChatWidget8() in ..\qq_test_new\drawer.cpp:73

QObject::connect: No such slot QToolBox::showChatWidget9() in ..\qq_test_new\drawer.cpp:81

2.在pro文件里写”QT+=widgets”表示引入QtWidget这个module，qmake在生成makefile的时候，会设置好include path 和 lib path，在link时候设置好libs。
