踩

object::connect: parentheses expected, signal qthread::&qthread::finished

Object::connect: Parentheses expected, signal QAction::triggered

Object::connect: (receiver name: ‘MainWindow’)

提示很明白了，语句中少了括号！

像这样：

 connect(setPwdAct,SIGNAL(triggered),this,SLOT(setPWD()));
1

改写成：

connect(setPwdAct,SIGNAL(triggered()),this,SLOT(setPWD()));
1

在这里插入图片描述
就可以正常运行了
