c++ - Qt client programme -

i wrote program client on qt receive data server not receiving data , showing received bytes zero,following program:

//client.h

#ifndef client_h #define client_h  #include <qobject> #include <qstring> #include <qtnetwork/qtcpsocket>  class client: public qobject { q_object public:   client(qobject* parent = 0);   ~client();   void start(qstring address, quint16 port);   void send(const char*);   void receive(); public slots:   void starttransfer(); private:   qtcpsocket client; };  #endif // client_h 

//client.cpp

#include "client.h" #include <qtnetwork/qhostaddress> #include<qiodevice>  client::client(qobject* parent): qobject(parent) {     connect(&client, signal(connected()),     this, slot(starttransfer()));      //connect(&client, signal(waitforbyteswritten()),     //        this, slot(receive())); }  client::~client() {   client.close(); }  void client::start(qstring address, quint16 port) {   qhostaddress addr(address);   client.connecttohost(addr, port); }  void client::starttransfer() {   client.write("connection established", 22); }  void client::send(const char *buffer) {     client.write(buffer,sizeof(buffer)); }  void client::receive() {     char temp[1024] = {0};     int len = client.read(temp,client.bytesavailable());     printf("\tdata recieved server :: %s\n",temp);     printf("\tsize of data received :: %d\n",client.bytesavailable());     printf("\tbytes read :: %d\n",len); } 

//main.cpp

#include <qcoreapplication> #include "client.h" //#include <qapplication>  int main(int argc, char *argv[]) {     qcoreapplication a(argc, argv);      client client;     client.start("192.168.1.2", 9602);      char buff[] = "send operation performed main";     client.send(buff);    // while(1)     client.receive();      return a.exec(); } 

here program function executes , stops receiving(may be),when send thing server doesn't take anything.any suggestions? plz don't rude if have done silly programming mistake because i'm newbie.

you not getting @merlin069's answer....you should use readyread in signal's place , receieve function slot...it work.i hope easy language understandable you.
