当用户在OSX上按下COMMAND + [任何其他键]时，我正试图捕获一个事件。由于这些实际上是两次按键，我期待两个事件：一个是按下COMMAND，一个是按下另一个按键（不释放COMMAND键）。这适用于除COMMAND之外的每个修饰符，其中我只获得第一个事件。为什么这样，我该如何解决？
版本：wxPython3.0-osx-cocoa-py2.7
示例代码：
import wx
def OnKeyDown(e):
print "Modifiers: {} Key Code: {}".format(e.GetModifiers(), e.GetKeyCode())
app = wx.App()
frame = wx.Frame(None)
textctrl = wx.TextCtrl(frame, wx.ID_ANY, wx.EmptyString, wx.DefaultPosition, wx.DefaultSize, wx.WANTS_CHARS)
textctrl.Bind(wx.EVT_KEY_DOWN, OnKeyDown)
frame.Show()
app.MainLoop()
对于ALT + d，输出为：
Modifiers: 1 Key Code: 307
Modifiers: 1 Key Code: 68
对于SHIFT + d，输出为：
Modifiers: 4 Key Code: 306
Modifiers: 4 Key Code: 68
仅对于COMMAND + d，输出为：
Modifiers: 2 Key Code: 308
感谢您的帮助
其他信息：我在虚拟机上使用OSX 10.8 。正如RobinDunn指出它可以在他的笔记本电脑上运行。所以很有可能这只是我环境中的一个问题。 wnnmaw提供了一个很好的解决方法，即使在虚拟环境中也适用于我。

好吧，所以我花了一些时间，但这是一个可以完成你想要的工作代码块。
有些注意事项：
wx.ACCEL_RAW_CTRL的支持，该支持对应于Mac上的实际控制键，而wx.ACCCEL_CTRL对应于命令键没有进一步的说法，这里是
