Java Keylistener没有窗口打开？

我正在尝试用Java创建一个自动点击器(只有我知道的语言,我刚刚学习了Threads).我想让applet在它自己的窗口中打开(不在网页上),我希望能够在没有选择窗口的情况下使用空格键启动和停止程序,这样我就可以在另一个程序上使用自动点击器并且能够在没有alt-f4ing一堆东西的情况下阻止它.

有什么可以推荐给我的,可以帮助我吗？或者你有什么建议吗？

迟到的答案,但希望有帮助:)

你可以使用JNA,这是一个很棒的!

得到JNA(jna.jar)

在表单中为User32(User32.dll)创建自己的映射

public interface User32 extends StdCallLibrary {
User32 INSTANCE = (User32) Native.loadLibrary("User32", User32.class,   Options.UNICODE_OPTIONS);


// dwWakeMask Constants
public static final int QS_ALLEVENTS = 0x04BF;
public static final int QS_ALLINPUT = 0x04FF;
public static final int QS_ALLPOSTMESSAGE = 0x0100;
public static final int QS_HOTKEY = 0x0080;
public static final int QS_INPUT = 0x407;
public static final int QS_KEY = 0x0001;
public static final int QS_MOUSE = 0x0006;

public static final int QS_RAWINPUT = 0x0400;
public static final int QS_SENDMESSAGE = 0x0040;
public static final int QS_TIMER = 0x0010;


public static final int INFINITE =    0xFFFFFFFF;

创建一个这样的测试程序:

User32 user32 = User32.INSTANCE;
boolean res = user32.RegisterHotKey(Pointer.NULL, 9999, User32.MOD_ALT | User32.MOD_CONTROL, WINUSER.VK_LEFT);
if(!res)
  System.out.println("Couldn't register hotkey");

System.out.println("Starting and waiting");
user32.MsgWaitForMultipleObjects(0, Pointer.NULL, true, User32.INFINITE, User32.QS_HOTKEY);
System.out.println("Ending");

User32.INFINITE是一个未记录的常量,其值为0xFFFFFFFF
