在 wxPython 中，如何将 EVT_KEY_DOWN 事件绑定到整个窗口?
问题描述：
我可以将事件绑定到 textctrl 框 np.问题是我必须在 textctrl 框内单击才能捕获"此事件.我希望能够在主窗口有焦点时任何时候有人按下箭头键.
I can bind an event to a textctrl box np. The problem is I have to be clicked inside of the textctrl box to "catch" this event. I am hoping to be able to catch anytime someone presses the Arrow keys while the main window has focus.
不工作:
wx.EVT_KEY_DOWN(self, self.OnKeyDown)
工作:
self.NudgeTxt = wx.TextCtrl(self.panel, size=(40,20), value=str(5))
wx.EVT_KEY_DOWN(self.NudgeTxt, self.OnKeyDown)
我很确定我错过了一些简单的东西.但是我有点卡住了.
I am pretty sure I am missing something easy. However am a bit stuck.

改为尝试绑定到 wx.EVT_CHAR_HOOK
例如...
self.Bind(wx.EVT_CHAR_HOOK, self.onKey)
...
def onKey(self, evt):
if evt.GetKeyCode() == wx.WXK_DOWN:
print "Down key pressed"
else:
evt.Skip()
