How to get Graphics object in Draw2d? [message #238399]

Hello everyone,
How can I get a Graphics object in Draw2d System? Like SWT, I can get a
GC object by new GC(Drawable),but how in Draw2d?
I want to get this, becase I want to draw a rectangle centered by mouse
position, and when the mouse moves, the rectangle either. According to my
experince in SWT, draw the rectangle in MouseMotionListener is better, but
this requires GC object, so I want to get Graphics in Draw2d. Or is there
another way to do this in Draw2d?
Thanks very much!

Hope this helps.
1. You can make use of set cursor on base figure.
2. Gets graphics object
Image img1 = new Image(null, new org.eclipse.swt.graphics.Rectangle(10, 102, 600, 600));
GC gc1 = new GC(img1);
Graphics grap1 = new SWTGraphics(gc1);
contents.paint(grap1);
