title: Draw on QWidget
body: <p><strong>How can I draw on QWidget(element on my form)?</strong></p>
  
  <p>I read many tutorials but none of them covers what I really have to do(draw some Rect on QWidget) . </p>
  
  <p>I made a class MyFigure which inherits from QWidget, and at even paint wrote some code to draw a rectangle.
  Then, in my Form Create I create MyFigure object, and just show it.</p>
  
  <p>IT DOESN"T WORK!!!</p>
