捕获控件+空格键事件

Question

I want leftCanvas to capture all keyboard events, including Control + Space . How can I achieve that since it is triggering the native InputMethod ?

class leftCanvas extends Canvas implements KeyListener {
    leftCanvas() {
        addKeyListener(this);
        enableInputMethods(false);
    }
    public void keyTyped(KeyEvent event) {
        System.out.println(event.getKeyChar());
        event.consume();
    }
    public void keyPressed(KeyEvent event) {
        event.consume();
    }
    public void keyReleased(KeyEvent event) {
        event.consume();
    }
}

Answer 1

I have to deal with system global hotkeys, like Super + E .

It seems JNI is necessary, and I found the project jnativehook which looks really good!
