[Soumya Somasekhar Ram]

I want to display the text in the LineEdit using Qt.
but when i use the code an empty string wiil be displayed.
The following is my code.

if( QPushButton *button = (QPushButton *)sender())
    {// it's a "QPushButton", do something with pb here
  QFrame* popup1 = new QFrame(this, Qt::Tool | Qt::Window );
     popup1->setWindowTitle("Rename the folder");
     QLineEdit *lb=new QLineEdit(popup1);
     connect( lb, SIGNAL( returnPressed() ), lb, SLOT( hide() ) );
     lb->setFocus();
     lb->show();
     lb->move(QCursor::pos());
      qDebug()<<lb->text();
     button->setText(lb->text());
     button->setObjectName(lb->text());
 
    }    }

if( QPushButton *button = (QPushButton *)sender())
    {// it's a "QPushButton", do something with pb here
  QFrame* popup1 = new QFrame(this, Qt::Tool | Qt::Window );
     popup1->setWindowTitle("Rename the folder");
     QLineEdit *lb=new QLineEdit(popup1);
     connect( lb, SIGNAL( returnPressed() ), lb, SLOT( hide() ) );
     lb->setFocus();
     lb->show();
     lb->move(QCursor::pos());
      qDebug()<<lb->text();
     button->setText(lb->text());
     button->setObjectName(lb->text());

    }    }

To copy to clipboard, switch view to plain text mode 

Can any one help me.
