Okay I get it ...
What uDig does is add a render callback; and every 100 or so draw callbacks is
asks its UI thread to draw the image to the screen again. It is actually a bit
more complicated in that we have a timer that will draw after 1,3,5, 5, 5
seconds; and the renderer is used to set a fl
Not sure I understand:
gc.drawImage( image )
Where image is the buffered image you are asking geotools to draw into on
another thread

swing module classes that I'm now doing...

/Can you please supply me with a code sample regarding how uDig does
that? We really need this feature, our customers dislike the time lag

Yes; a couple of ways.
- Draw the image as geotools is drawing into it... this is what uDig does.
- Get a volatile image and use that to draw into. It is tricky Java 2D
programming (because you need to redraw if windows are moved in front of your
image) but it is effective.

As far as I know, default geotools drawing mode is to draw on offline
buffer and then render this buffer to the screen. On the opposing side,
OpenJump (for example) draws everythink it can draw immediately.
This give user the feeling of more responsive interface, because hey -
something is going
