使用swt处理按键操作

Question

按下CTRL-C时 我想做someStuff().我写了一些代码,但它"不够好".我该怎么办？)

    //org.eclipse.draw2d.Shape getShape(){....}

    getShape().addKeyListener(new KeyListener(){

        @Override
        public void keyPressed(KeyEvent ke) {
        }

        @Override
        public void keyReleased(KeyEvent ke) {
            /*if CTRL-C pressed*/
            if((ke.getState() & KeyEvent.CONTROL) != 0 && 'c' == ('a' + ke.character - 1)){
                someStuff();
            } 
        }
    });

谢谢.

试试这个:

getShape().addListener(SWT.KeyUp, new Listener() {
    public void handleEvent(Event event) {
        if (event.stateMask == SWT.CTRL && event.keyCode == 'c') {
            someStuff();
        }
    }});
