Hi, i have created a c++ header file for network access and i am able access the network when i create instance in main.cpp, but it is not working(only network access like get,post… remains works fine) when i call it on a separate class.

Sync_Network.h

Qt Code: 
  1. #include <QNetworkAccessManager>
  2. #include <QNetworkReply>
  3. #include <QNetworkRequest>
  4. #include <QDebug>
  5. #include <QUrl>
  6. class Sync_Network:public QNetworkAccessManager{
  7.     Q_OBJECT
  8.     public:
  9.         Sync_Network(QString url,QObject *parent=0):QNetworkAccessManager(parent),host(url){
  10. connect(this,SIGNAL(finished(QNetworkReply*)),this,SLOT(showReply(QNetworkReply*)));
  11. }
  12.         virtual ~Sync_Network(){}
  13.         bool Sync_Get(const QString path){
  14.              get(QNetworkRequest(QUrl(host+""+path)));
  15.              return status;
  16.         }
  17.         bool Sync_Post(QString params,QString path=""){
  18.             QByteArray data;
  19.             data.append(params);
  20.             post(QNetworkRequest(QUrl(host+""+path)),data);
  21.             return status;
  22.         }
  23.     protected slots:
  24.         virtual void showReply(QNetworkReply *reply){
  25.             if(!reply->error()) qDebug()<<reply->readAll();
  26.             else{
  27.                 status=false;
  28.                 qDebug()<<reply->errorString();
  29.             }
  30.         }
  31.     private:
  32.         bool status;
  33.         QString host;
  34. };
