Question

我正在制作一个自动点击器，它使用jna来连接键盘和鼠标的全局输入。对于使用http://code.google.com/p/goldriver/source/browse/trunk/king/src/jnacontrib/w32keyhook/KeyHook.java?r=36的键盘挂钩。

我想知道是否有任何可能的方法来使用密钥事件，以便其他应用程序不处理它？</ p>

修复了返回新LRESULT（1）;

现在我遇到了问题，没有继续使用其余的代码，这里是源代码。我的程序一直在监听键盘输入，并且不会继续显示GUI。

public class GUI extends javax.swing.JFrame{

ArrayList<MEvent> events;

public static final int RUNNING = 0;
public static final int PAUSED = 1;
public static final int STOPPED = 2;
public static final int LISTENING = 3;

private int process = STOPPED;
private String display;

private JTable Events;
DefaultTableModel list;
Loader loader;
private static MouseHook mh;
static private KeyHook kh;
static GUI gui;
Robot robot;

/** Creates new form GUI */
public GUI() {
    initComponents();
    loader = new Loader(this);
    events = new ArrayList<MEvent>();
    list = new DefaultTableModel();
    mh = new MouseHook(this,list);
    mh.setMouseHook();

    list.addColumn("Type");
    list.addColumn("X");
    list.addColumn("Y");
    list.addColumn("Sleep");
    try {
        robot = new Robot();
    } catch (AWTException ex) {}


    displayProcess(process);
    Events.setModel(list);
    kh = new KeyHook(this);
    kh.run();
}

public static void main(String args[]) {

    java.awt.EventQueue.invokeLater(new Runnable() {
        public void run() {
            gui = new GUI();
            gui.setVisible(true);
        }
    });


}

}

public class KeyHook implements Runnable{
private static volatile boolean quit;

Answer 1

是的，不要打电话

return lib.CallNextHookEx(hhk, nCode, wParam, info.getPointer());

在回叫方法中，......但那是一件很邪恶的事情，不是吗？如果不是邪恶，有潜在的危险。

使用jna来keyhook和消费
