QPainter reuse within a paintEvent

[aamer4yu]

And why cant u use it like -

MyWidget::paintEvent( QPaintEvent *event )
      {
         QPainter painter(this);
         painter.drawPixmap(,,,,,,);
         painter.some_painting_stuff1();
         painter.some_painting_stuff2();
      }

MyWidget::paintEvent( QPaintEvent *event )
      {
         QPainter painter(this);
         painter.drawPixmap(,,,,,,);
         painter.some_painting_stuff1();
         painter.some_painting_stuff2();
      }

To copy to clipboard, switch view to plain text mode 

Is there some problem or restriction in doing so ??

Because for some odd reason, I had it in my head to create the pixmap within the paintEvent, then display it with the new painter(this) painting on the widget. Of course I have code that detects when the pixmap needs to be redrawn. 99% of the time it doesn't need to be redrawn so it should just copy the previous one onto the widget.

I was having some weird problems and I wanted to know if what I was doing was ok.

I have since changed the code around to generate the pixmap in a separate method and have had better results so obviously what I was doing was causing the weird problem. I just wanted to know why?
