自定义的槽无响应
MainWindow里用stackedWidget管理了pView，pReview两个界面，可以同个按钮切换

创建如下
MainWindow::MainWindow(Connector* Conn, QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow),
pReview(new Ui::Review),
pView(new Ui::View),
{
ui->setupUi(this);

pViewWidget = new QWidget(ui->stackedWidget);
pReviewWidget = new QWidget(ui->stackedWidget);
pView->setupUi(pViewWidget);
pReview->setupUi(pReviewWidget);
ui->stackedWidget->addWidget(pViewWidget);
ui->stackedWidget->addWidget(pReviewWidget);

setCentralWidget(ui->stackedWidget);
ui->stackedWidget->setCurrentIndex(2);
}

View 里有个按钮它的clicked是连接到AddNode的，但是点了AddNode没有响应
class View : public QWidget
{
Q_OBJECT

public:
explicit View(QWidget *parent = 0);
~View();

public slots:
void AddNode(void);

private:
Ui::View *ui;
};

View::View(QWidget *parent) :
QWidget(parent),
ui(new Ui::View)
{

QObject::connect(ui->pushButton, SIGNAL(clicked()), this, SLOT(AddNode()));

ui->setupUi(this);
}

void View::AddNode(void)
{
QMessageBox::about(NULL, "dd", "dsdf");
}


View 里有个按钮pushButton
但是点了没有响应
[解决办法]
打断点调试一下。
[解决办法]
看一下connect返回值是true吗
[解决办法]

QObject::connect(ui->pushButton, SIGNAL(clicked()), this, SLOT(AddNode()));

ui->setupUi(this); 改成：

ui->setupUi(this);
QObject::connect(ui->pushButton, SIGNAL(clicked()), this, SLOT(AddNode()));
