@rezaMSLM

MainWindow::MainWindow()
{
    connect(&ftp, SIGNAL(stateChanged(int)), this, SLOT(checkState(int)));
}

void MainWindow::checkState(int state)
{
    switch(state) {
    case QFtp::Connected:
        break;
    ...
    }
}

// From QFtp header file:
enum State {
        Unconnected,
        HostLookup,
        Connecting,
        Connected,
        LoggedIn,
        Closing
};

my program has a BUG:
when I'm already Connected to server and I Click on Connect button again none of the buttons will work.
neither login nor disconnect buttons

my mainwindow.cpp:

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QtNetwork/QFtp>


MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)

{
    ui->setupUi(this);
    ftp = new QFtp(parent);
    connect(ftp, SIGNAL(stateChanged(int)), this, SLOT(checkState(int)));
}

MainWindow::~MainWindow()
{
    delete ui;
    delete ftp;
}

void MainWindow::checkState(int state)
{
    switch(state) {
    case QFtp::Connected:
        ui->Connect_Status_Label->setText("Connected");
        break;
    case QFtp::Unconnected:
        ui->Connect_Status_Label->setText("UnConnected");
        ui->Login_Status_Label->setText("Logged Out");
        break;
    case QFtp:: LoggedIn:
        ui->Login_Status_Label->setText("Logged in");
        break;
    }
}

void MainWindow::on_pushButton_Connect_clicked()
{
    QString Host = ui->lineEdit_Host->text();
    ftp->connectToHost(Host);
}

void MainWindow::on_pushButton_Login_clicked()
{
    QString UserName = ui->lineEdit_User->text();
    QString PassWord = ui->lineEdit_Pass->text();
    ftp->login(UserName,PassWord);
}

void MainWindow::on_pushButton_DisConnect_clicked()
{
    ftp->close();
}

what is the reason?

@rezaMSLM I don't understand: you're connected and then click connected again? Afterwards disconnect doesn't work? Does disconnect work if you don't click connect when already connected? You should disable the connect button if already connected and enable it when disconnected.
