[news.eclipse.platform.swt] SWT constant for space key

[e@xxxxx (Erel)]

I would like to display content assist information when the user presses 
both the CTRL and SPACE keys. 

the code looks the following:
       sourceViewer.getControl().addKeyListener(new KeyAdapter() {
           public void keyPressed(KeyEvent e) {
               switch (e.keyCode) {
               case // CTRL and SPACE  :
                   assistant.showPossibleCompletions();
                   break;
               default:
                   //ignore everything else
               }
           }
       });

I couldn't find SWT.SPACE and how do I capture when the user presses both 
keys?

thanks in advance
