修改器键状态

myComponent.add<Any>Listener(new <Appropriate>Listener(){
    @Override
    public void <AppropriateMethod>(like KeyPress)>(<Appropriate>Event e) {
        int stateMask=e.stateMask;
        if((stateMask & SWT.ALT)==SWT.ALT){
            <Do_appropriate_actions>;
        }
        if((stateMask & SWT.CTRL)==SWT.CTRL){
            <Do_another_appropriate_actions>;
        }
        if((stateMask & SWT.SHIFT)==SWT.SHIFT){
            <Do_an_even_more_appropriate_actions_cause_you_are_kind_of_a_code_roxxor_!>;
        }
    };
};

希望它能有所帮助。..

尝试以下方法来捕获所有密钥并保存以备后用:

    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 );
        }
    } );

您可以使用以下方法测试修饰符键:

/**
 * Key code of pressed modifier key.
 *
 * @param keyEvent the received key event
 * @return the key code or 0 if no modifier key is pressed
 */
private static int getModifierKeyCode(KeyEvent keyEvent) {
    return (keyEvent.stateMask & SWT.MODIFIER_MASK);
}

示例调用:

item.addKeyListener(new KeyAdapter() {
    @Override
    public void keyPressed(KeyEvent keyEvent) {
        if(getModifierKeyCode(keyEvent) == SWT.CTRL && keyEvent.keyCode == 'f') { // CTRL + F
            // do something
        )
    }
}
