[news.eclipse.platform.swt] Display.getDefault().asyncExec

[mr_squirtle23@xxxxxxxxx (Mark R)]

Hello,

I am debugging an SWT program written by someone and I keep on 
encountering the code

Display.getDefault().asyncExec(new Runnable()
{
public void run() {
//many code
}
}

I really dont get what this code does. I tried googling for this phrase 
but cant found a nice resource to learn about this.  Does someone has link 
discussing about this?
Please bear with me as I really am starting to know about SWT.
