    ui->setupUi(this);
    QObject::connect(ui->shotScreenButton,SIGNAL(clicked()),this,SLOT(newShotScreenSlot()));
    QObject::connect(ui->saveButton,SIGNAL(clicked()),this,SLOT(saveScreenSlot()));

}

Screenshot::~Screenshot()

}

void Screenshot::newShotScreenSlot()
{
     if(ui->hideCheckBox->isChecked())
    {
          this->hide();
          this->timer =new QTimer;

          QObject::connect(this->timer,SIGNAL(timeout()),this,SLOT(shotScreenSlot()));
          this->timer->start(ui->timeSpinBox->value()*1000);

     }
     else
     {
           qApp->beep();

void Screenshot::shotScreenSlot()
{
    this->pixmap= QPixmap::grabWindow(QApplication::desktop()->winId());
    ui->screenLabel->setPixmap(pixmap.scaled(ui->screenLabel->size()));
    this->timer->stop();

void Screenshot::saveScreenSlot()
{
