QPushButton* btn1 = new QPushButton("Create",this);
QPushButton* btn2 = new QPushButton("Destroy",this);

QVBoxLayout* mainLaout =new QVBoxLayout(widget);
mainLaout->addWidget(btn1);
mainLaout->addWidget(btn2);

connect(btn1,SIGNAL(clicked()),this,SLOT(create()));
connect(btn2,SIGNAL(clicked()),this,SLOT(destroy()));

setCentralWidget(widget);
}

void MainWindow::create()
