QPainter reuse within a paintEvent

[Micawber]

Is it possible/wise to re-use a QPainter within the paintEvent message? Something like...

MyWidget::paintEvent( QPaintEvent *event )
{
 
   QPainter painter;
 
   painter.begin( m_pixmap );
   painter.initFrom( this );
   painter.some_painting_stuff();
   painter.end();
 
   painter.begin( this );
   painter.initFrom( this );
   painter.some_painting_stuff();
   painter.end();
}

MyWidget::paintEvent( QPaintEvent *event )
{

   QPainter painter;

   painter.begin( m_pixmap );
   painter.initFrom( this );
   painter.some_painting_stuff();
   painter.end();

   painter.begin( this );
   painter.initFrom( this );
   painter.some_painting_stuff();
   painter.end();
}
