QT--多TCP客户端

整体效果图如下：

1、tcpclient.h

#ifndef TCPCLIENT_H
#define TCPCLIENT_H#include <QWidget>
#include <QPushButton>
#include <QTextEdit>
#include <QHBoxLayout>
#include <QVBoxLayout>
#include <QTcpSocket>

#include <QTimer>class TcpClient : public QWidget
{Q_OBJECT
public:TcpClient(QWidget *parent = 0);QTcpSocket *tcpsocket;QTimer *timer;int state;void getShow();void connect_to_server(QString IP,int Port);//连接服务器void setText_to_show(QString m);public slots:void press_send();void CheckBox_state(int arg1);void time_during();protected:QPushButton *Btn_cnt,*Btn_discnt,*Btn_send;QTextEdit *EditShow;QHBoxLayout *HLayout;QHBoxLayout *HLayout1;QVBoxLayout *VLayout;QVBoxLayout *VLayout1;QCheckBox *CheckBox;QLineEdit *time_space;QLabel *lable;};#endif // TCPCLIENT_H

2、tcpclient.c

5、mainwindows.h

#ifndef MAINWINDOW_H

6、mainwindows.c

#include "mainwindow.h"
