QT 简单QNetwork历程无法使用

新手求教，历程无法使用，在debug的时候在replyfinished函数开始处设置断点，一直没有触发
这是pro文件：
QT += core gui network
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = weatherget
TEMPLATE = app

SOURCES += main.cpp\
mainwindow.cpp

HEADERS += mainwindow.h

FORMS += mainwindow.ui

这是头文件：
#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include
#include
#include
#include

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget parent = 0);
~MainWindow();
private:
void replyFinished(QNetworkReply);
private:
Ui::MainWindow *ui;
QNetworkAccessManager *manager;

};

#endif // MAINWINDOW_H

这是源文件：
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include
MainWindow::MainWindow(QWidget parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
QUrl url(QString("http://www.weather.com.cn/adat/sk/101010100.html"));
manager = new QNetworkAccessManager(this);
QNetworkRequest request;
request.setHeader(QNetworkRequest::ContentTypeHeader,"application/json");
request.setUrl(url);
manager->get(request);
connect(manager,SIGNAL(finished(QNetworkReply)),this,SLOT(replyFinished(QNetworkReply*)));
}

MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::replyFinished(QNetworkReply *reply)
{
QTextCodec *codec = QTextCodec::codecForName("utf8");
QString all=codec->toUnicode((reply->readAll()));
ui->textBrowser->setText(all);
reply->deleteLater();
}

知道哪里错了，replyfinished函数没有在h文件里声明为publick slots，问题结束

楼主，1、你写的这里
“private:
void replyFinished(QNetworkReply);”
并不是 slot槽；
2、“connect(manager,SIGNAL(finished(QNetworkReply)),this,SLOT(replyFinished(QNetworkReply*)));” 中 信号和槽 的 参数不一致，一个是 对象，一个是指针；
改过来就好了
