now i want to show this words one by one after i click on Next button but with this code i only get "Good" text i mean when i click on next button doesnt show me other words. in overall my goal is when i click on next show me "good" word after i click it again show me "bad" after i click again show me "hi" here is my code with Qt 5.4

void MainWindow::on_Next_clicked()  
{  
    ui->ShowEn->clear();   
    ifstream Sfile("E:\\en.txt");   
    getData(Sfile);   
   Sfile.close();  
}  
void MainWindow::getData(std::ifstream& myfile){
 
    if(!myfile.eof())
    {
        std::string str;
      getline(myfile, str);
      ui->ShowEn->setText(QString::fromStdString(str));
    }
}

void MainWindow::on_Next_clicked()  
{  
    ui->ShowEn->clear();   
    ifstream Sfile("E:\\en.txt");   
    getData(Sfile);   
   Sfile.close();  
}  
void MainWindow::getData(std::ifstream& myfile){

    if(!myfile.eof())
    {
        std::string str;
      getline(myfile, str);
      ui->ShowEn->setText(QString::fromStdString(str));
    }
}

To copy to clipboard, switch view to plain text mode

You are re-opening the file on every click of Next button, instead open the file only once and call getLine() on every Next click.
