Hi,
what exactly you would to do?
You cannot close a widget contained by other widget. you can hide it

I print on screen "Press Q to quit program"
with keypressevent i check whether user presses Q_Key.

void myproject::keyPressEvent ( QKeyEvent * event )
{
	if(event->key() == Qt::Key_Q)
	{
	ui->close();
	}
}

void myproject::keyPressEvent ( QKeyEvent * event )
{
	if(event->key() == Qt::Key_Q)
	{
	ui->close();
	}
}

i said false.
i'm trying to quit application, not the widget.

this code doesn't work..

void myproject::keyPressEvent ( QKeyEvent * event )
{
	if(event->key() == Qt::Key_Q)
	{
	app.quit();
	}
}

void myproject::keyPressEvent ( QKeyEvent * event )
{
	if(event->key() == Qt::Key_Q)
	{
	app.quit();
	}
}
