Widget::Widget(QWidget *parent) :
QWidget(parent),
ui(new Ui::Widget)
{
ui->setupUi(this);

QTimer::singleShot(1000,this, SLOT(shutdownlabel()));

mtime=   QDateTime::currentMSecsSinceEpoch();

}

Widget::~Widget()
{
delete ui;
}

void Widget::shutdownlabel()
{

qint64 Newtime  = QDateTime::currentMSecsSinceEpoch() - mtime;
//PRINT_INFO<<"newtime: " << Newtime/1000;
Timeremain =  TIMEOUT - (Newtime/1000);

QLabel *label = new QLabel(ui->frame_2);
label->setStyleSheet("border:1px solid black;text-align:cetre;");
label->setGeometry(50,1,202,20);
label->clear();
label->setText("Timer:" +QString::number(Timeremain));
label->show();

QTimer::singleShot(1000,this, SLOT(shutdownlabel()));

when i use this dynamic label in slot its slot create n label at same place and so its get overlapped to avoid this i need to take dynamic label as global and clear it every time

Use layouts (subclasses of QLayout) instead of manual positioning (setGeometry()).

That sounds like a very wasteful approach... If you need a label there, just insert it upfront. If it does not need to be visible - hide it. If it needs to be visible - show it. If it's text needs to be changed, call setText() in your slot.

There is no need to keep adding/ deleting labels, or clearing a global one etc.
