Question

以下程序适用于Windows，但不适用于Linux。当我按下我绑定的键时，没有显示打印语句。但是，Tab键可以在两个按钮之间切换，enter和space键可以切换它们。没有其他钥匙可以工作。

import wx

class MyForm(wx.Frame):
    def __init__(self):
            wx.Frame.__init__(self, None, wx.ID_ANY, "Pressing dem keyz")

            # Add a panel so it looks the correct on all platforms
            panel = wx.Panel(self, wx.ID_ANY)
            self.btn = wx.ToggleButton(panel, label="TOGGLE")
            self.btn2 = wx.ToggleButton(panel, label="TOGGLE 2", pos = (85,0))

            self.btn.Bind(wx.EVT_CHAR_HOOK, self.onKeyPress)
            self.btn2.Bind(wx.EVT_CHAR_HOOK, self.onKeyPress)

    def onKeyPress(self, event):
            space = False
            keycode = event.GetKeyCode()
            print keycode
            if keycode == wx.WXK_SPACE: 
                    print "SPACEBAR!"
                    space = True
            self.btn.SetValue(space)
            if space == True:
                    print "Do something"
            elif keycode == wx.WXK_RETURN:
                    self.Hello()
            elif keycode == wx.WXK_LEFT:
                    self.btn2
                    print 'YOU MOVED LEFT'
            elif keycode == wx.WXK_RIGHT:
                    self.btn
                    print 'YOU MOVED RIGHT'
            elif keycode == wx.WXK_UP:
                    print 'YOU MOVED UP'
            elif keycode == wx.WXK_DOWN:
                    print 'YOU MOVED DOWN'
            elif keycode == wx.WXK_ESCAPE:
                    self.Destroy()
    def Hello(self):
            print "Hello"
            return
 # Run the program
if __name__ == "__main__":
        app = wx.App(False)
        frame = MyForm()
        frame.Show()
        app.MainLoop()

Answer 1

而不是使用EVT_CHAR_HOOK使用EVT_KEY_DOWN。

Answer 2

或者确实，EVT_KEY_UP
它解决了按键给出多个按键事件的问题。

wxPython Key Bindings不适用于Linux
