[SWT] Modifier Key state

Question

Hi all,

I have a tiny (rikiki) problem in SWT ...

I am making a small class extending org.eclipse.swt.widgets.Composite and which is supposed to be nested in an RCP app ...

In this small class I have widgets which are supposed to react to mouse or keyboard event

BUT

I need to use modifier keys (Shift/Ctrl/Alt/...) to alter my coponents behaviours when I click them or send them keyboard event ...

The probleme is that I cannot just listen for mod-key striking because my user can strike it out from my component and then click it...

I cannot use a display filter to avoid disturbing the shell that nests my component.(but may be it will be my last solution in case there is no other solution)

I cannot make a transparent component that reads and dispatch events to all of my components because it would, at the most, be as large as my component and wont get mod-key strikes from the shell out my component (or even out from the shell) ...

Do anyone have any idea?

Try something along these lines to capture all keys and save them for later:

 Display.getDefault().addFilter( SWT.KeyDown, new Listener() {

  public void handleEvent( Event passedEvent ) {
   //Listen for and store as static var last pressed keycode
   System.out.println( "Key Event: " + passedEvent );
  }
 } );
