Method display should be defined as slot and looks like :

void MainWindow::display()
{
    label->setVisible(!label->isVisible());// Set the status of the opposite
    QTimer::singleShot(500,this,SLOT(display()));// call display() after 500 ms
}

void MainWindow::display()
{
    label->setVisible(!label->isVisible());// Set the status of the opposite
    QTimer::singleShot(500,this,SLOT(display()));// call display() after 500 ms
}

To copy to clipboard, switch view to plain text mode

Run your program in your debugger. When it crashes look at where it crashed in the back trace you will likely be given.
