why does the chicken cross the road?


« Posted 2004-08-16 12:01:16 »

i draw my images with

g.drawImage(aImage, xpos, ypos, null);

the last parameter should be a ImageObserver ( a panel has a ImageObserver Interface )

whats the difference between using null or this, any speedups or any problem when i use null Huh?

Huh

If you don't need any additional info through the ImageObservers callback interface (or you are drawing an Image type that doesn't use the callback anyway) there is no reason not to pass in null.

Passing in null will also generate slightly smaller bytecode, and may execute insignificantly more quick.
