SWT Canvas DoubleBuffering to prevent flickering

There are already some examples of how to prevent flicker when drawing to an SWT Canvas.

Unfortunately, some of the examples, like this one:

http://www.java2s.com/Code/Java/SWT-JFace-Eclipse/DoubleBuffer.htm

just didn't work for me when I tried it out.

Researching a bit more on the internet got me the real nice and easy solution, which was to build the Canvas using the style SWT.DOUBLE_BUFFERED.

Basically, use:

new Canvas( parent, SWT.DOUBLE_BUFFERED);

and you should be good to go.

It's just one of those things that makes life so much easier...
