挂钩event.Injected？

Question

这里确实是一个问题。基于 pyHook's tutorial，函数中的 .HookManager().OnMouseEvent 事件变量具有 .Injected 属性。没找到相关资料，请问有人知道是什么吗？我试过

event.Injected = '<char to inject>'

但是没用。

免责声明：我不是这方面的专家，我只是分享我对 tutorial and the documentation 的观察，希望对您有所帮助。

event上的属性不让你手动设置，但供您的事件处理程序阅读和采取行动。

如您在 KeyboardEvent and MouseEvent 的文档中所见， Injected 实例变量的目的是检查事件是否以编程方式生成。我认为，这意味着您的处理程序从鼠标和键盘 activity 接收到的事件将始终具有此变量 False。并且有一种以编程方式生成事件的方法，我想是为了测试您的处理程序。该方法似乎是 HookManager.KeyboardSwitch and HookManager.MouseSwitch.

例如试试这个。创建一个简单的程序来查看一些真实键盘事件的细节：

import pythoncom, pyHook

def OnKeyboardEvent(event):
    print 'MessageName:',event.MessageName
    print 'Message:',event.Message
    print 'Time:',event.Time
    print 'Window:',event.Window
    print 'WindowName:',event.WindowName
    print 'Ascii:', event.Ascii, chr(event.Ascii)
    print 'Key:', event.Key
    print 'KeyID:', event.KeyID
    print 'ScanCode:', event.ScanCode
    print 'Extended:', event.Extended
    print 'Injected:', event.Injected
    print 'Alt', event.Alt
    print 'Transition', event.Transition
    print '---'

    # return True to pass the event to other handlers
    return True

# create a hook manager
hm = pyHook.HookManager()

# watch for key press events
hm.KeyDown = OnKeyboardEvent

# set the hook
hm.HookKeyboard()

# wait forever
pythoncom.PumpMessages()

按几个键并观察输出。按 Control-C 终止程序。

然后，以编程方式生成一些事件并查看它们的外观，尝试这样的事情：

import pythoncom, pyHook

def OnKeyboardEvent(event):
    # ... same code as in previous sample ...

# create a hook manager
hm = pyHook.HookManager()

# watch for key press events
hm.KeyDown = OnKeyboardEvent

# set the hook
hm.HookKeyboard()

# send keyboard event programmatically
msg = ...       # a value like in the "Message: ..." output in the previous run
vk_code = ...   # a value like in the "KeyID: ..." output in the previous run
scan_code = ... # a value like in the "ScanCode: ..." output in the previous run
ascii = ...     # a value like in the "Ascii: ..." output in the previous run
flags = 0x10    # see http://pyhook.sourceforge.net/doc_1.5.0/pyhook.HookManager-pysrc.html#KeyboardEvent.IsInjected
time = ...      # a value like in the "Time: ..." output in the previous run
hwnd = ...      # a value like in the "Window: ..." output in the previous run
win_name = ...  # a value like in the "WindowName: ..." output in the previous run
hm.KeyboardSwitch(msg, vk_code, scan_code, ascii, flags, time, hwnd, win_name)

设置适当的值后，运行这个程序，你应该在输出中看到 "Injected: True"。

我认为这是基本思路，鼠标事件也是如此。不幸的是我无法测试这个，因为 pyHook 似乎是 Windows OS 的库，我没有。
