wxPython 捕获按键消息

快捷键F1全屏：

import wx

class KeyEvent(wx.Frame):
def __init__(self, parent, id, title):
         wx.Frame.__init__(self, parent, id, title)
         panel = wx.Panel(self, -1)
         panel.Bind(wx.EVT_KEY_DOWN, self.OnKeyDown)
         panel.SetFocus()

         self.Centre()
         self.Show(True)

def OnKeyDown(self, event):
         keycode = event.GetKeyCode()
         if keycode == wx.WXK_F1:
           self.SetPosition((0,0))
           self.SetSize(wx.DisplaySize())           
         else:
           event.Skip() 

app = wx.App()
KeyEvent(None, -1, 'keyevent.py')
app.MainLoop()

        self.Bind(wx.EVT_KEY_DOWN, self.OnKeyDown)
        
        self.Centre()
        self.Show(True)
 
    def OnKeyDown(self, event):
        #按键时相应代码
        kc=event.GetKeyCode()
        if 32<=kc<=126:
            self.SetTitle(chr(kc))

app = wx.App()
KeyEvent(None, -1, 'Test KeyDown Event of wxPython')
app.MainLoop()
