[JAVA3D] Canvas graphics draw - bug or feature?

[Andrei Moisseev]

Hi! I have made a simple example. Mouse events are processing in this example. On click and on drag the rectangle is drawing. And if in the same case the key Ctrl is pressed then an oval is drawing.          ....         Graphics g = canvas.getGraphics();         g.setColor( Color.WHITE);         if ( e.isControlDown() )           g.drawOval(start_point.x, start_point.y, end_point.x - start_point.x, end_point.y - start_point.y);         else           g.drawRect(start_point.x, start_point.y, end_point.x - start_point.x, end_point.y - start_point.y);         //swap canvas buffers         canvas.swap();         .... The rectangle is drawing normally but the oval is blinking during the draw. Is this a bug or a feature?   Best regards! Andrei Moisseev
