qtクライアントの実装

1、 .hファイル

#ifndef CLIENT_H
#define CLIENT_H

#include 
#include 


namespace Ui {
class client;
}

class client : public QWidget
{
    Q_OBJECT

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

private slots:
    void on_Button_Connect_clicked();

    void on_Button_Close_clicked();

    void on_Button_Send_clicked();

private:
    Ui::client *ui;

    QTcpSocket *sock;
};

#endif // CLIENT_H

2、cppファイル

#include "client.h"
#include "ui_client.h"
#include 


client::client(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::client)
{
    ui->setupUi(this);

    sock = NULL;

    sock = new QTcpSocket(this);    //set a client object





}

client::~client()
{
    delete ui;
}

void client::on_Button_Connect_clicked()
{

    //get ip and port
    QString ip = ui->le_IP->text();
    qint16  port = ui->le_port->text().toInt();

    //connect with sever
    sock->connectToHost(QHostAddress(ip),port);
