Hi
I want to have something like a speedometer. I draw it with Java2D

If I have now an event, then I want to change to position of "filledPolygon". How can I do that?
I found out, that i can translate the Graphics2D-Object, but this does not affect on my already created "filledPolygon" !
Any ideas?
Thanks, Flavio

If you are doing this inside the paint() method of an AWT component, or the paintComponent() method of a Swing component, you'll simply update all of the values you need to (i.e. x, y, yo1, yu1, x1, x2, yo2, etc.), and then call repaint().
 
It is sorta covered in the JavaRanch Style Guide.
