Nothing is wrong here.
[quote]When tabsClosable is set to true a close button will appear on the tab on either the left or right hand side depending upon the style. When the button is clicked the signal tabCloseRequested will be emitted.[/quote]
You will have to connect to the tabCloseRequested signal and remove tabs using removeTab() as requested.

but when i close one tab,, all tabs will closes....
@connect(ui->tabWidget,SIGNAL(tabCloseRequested(int)),this,SLOT(slotCloseTab(int)));@

Please provide a small compilable example that allows me to reproduce your problem - I can't with the code you've posted.
@
class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);

public slots:
void closeTab(int index);

private:
QTabWidget *tabWidget;
};

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent)
{
tabWidget = new QTabWidget;

tabWidget->setTabsClosable(true);

tabWidget->addTab(new QWidget, "Tab One");
tabWidget->addTab(new QWidget, "Tab Two");
tabWidget->addTab(new QWidget, "Tab Three");

connect(tabWidget, SIGNAL(tabCloseRequested(int)), this, SLOT(closeTab(int)));

setCentralWidget(tabWidget);

}

void MainWindow::closeTab(int index)
{
tabWidget->removeTab(index);
}

I'm creating TabWidget using designer, before running the program and adding widget in runtime...in this case
if i close "tab three", then "tab three" closes thats fine,,,,
But if i close "tab two", then both "tab two" and "tab three" closes
and if i close "tab one", then all tab closes...i,e "tab one ", "tab two" and "tab three" closes....
whats wrong here? please help me,,,,,

MainWin.h
@class MainWindow : public QMainWindow
{
Q_OBJECT

public slots:
void slotCloseTab(int index);
}

MainWin.cpp
@
void MainWindow::DisplayFileContent(QString string)
{
textBox = new QTextBrowser;
ui->tabWidget->addTab(textBox,string);
connect(ui->tabWidget,SIGNAL(tabCloseRequested(int)),this,SLOT(slotCloseTab(int)));
f.close();
}

void MainWindow::slotCloseTab(int index)
