Question

I’m going to make a hidden dialog in my application that get visible with a keyboard combination (e.g. Five sequent Ctrl+Shift+i).
How Can I capture keyboard combination strokes globally on the entire application?

Thanks

I solved it by defining a DispatcherListener:

class DispatcherListener implements KeyEventDispatcher{
    private int level=0;

    public boolean dispatchKeyEvent(KeyEvent e) {
        if(e.getID() == KeyEvent.KEY_RELEASED){
            if(e.isControlDown() && e.isShiftDown()){
                if(this.level==0 && e.getKeyCode()==KeyEvent.VK_S){
                    level++;
                }else if(this.level==1 && e.getKeyCode()==KeyEvent.VK_H){
                    level++;
                }else if(this.level==2 && e.getKeyCode()==KeyEvent.VK_O){
                    level++;
                }else if(this.level==3 && e.getKeyCode()==KeyEvent.VK_W){
                    level=0;
                    this.showHiddenWindow((JFrame)SwingUtilities.getRoot(e.getComponent()));
                }else{
                    level=0;
                }

                //System.out.println( "level: " +  level );
            }
        }
        return false;
    }

and used it as this:

    KeyboardFocusManager manager = KeyboardFocusManager.getCurrentKeyboardFocusManager();
    manager.addKeyEventDispatcher( new DispatcherListener());

Thank you all
