look at this code, it only draw ONE ellipse.
I want to draw TWO ellipses.
What is wrong here??

shape.cpp
Qt Code: 
  1. void shape::paintEvent( QPaintEvent * )
  2. {
  3.     QPainter painter( this );
  4.  
  5. 	QRectF rectangle1(10.0, 20.0, 80.0, 60.0);	
  6. 	painter.drawEllipse(rectangle1);
  7.  
  8. 	QRectF rectangle2(100.0, 200.0, 80.0, 60.0);	
  9. 	painter.drawEllipse(rectangle2);
  10.  
  11. }
  12.  
  13. void shape::drawMyCircle()
  14. {
  15.  
  16. 	QPainter painter( this );
  17. 	QRectF rectangle(150.0, 250.0, 80.0, 60.0);
  18. 	painter.drawEllipse(rectangle);
  19.  
  20. }
