wxPython wx.KeyEvent GetKeyCode() [英] wxPython wx.KeyEvent GetKeyCode()

问题描述

我正在编写一个wxPython应用程序，该应用程序现在(其中)要在其中打印所按下键的名称.我有一本字典，例如将WXK_BACK映射到"back"，这似乎很理智.但是，我必须导入(包括?)哪个文件才能获得WXK_BACK的定义?

I am writing a wxPython app in which I want (at the moment) to print the name of the key that was pressed. I have a dictionary that maps, for example, the WXK_BACK to "back" which seems a sane. However, which file must I import (include?) to get the definition of WXK_BACK ?

我有import wx语句，但是不确定哪个特定文件包含机密

I have the import wx statement, but am unsure which specific file holds the secrets

推荐答案

在导入wx模块(例如

>>> import wx
>>> wx.WXK_BACK

您也不需要手动生成用于名称映射的密钥，例如，您可以自动生成用于名称映射的密钥代码.

also you do not need to generate key to name map by hand, you generate keycode to name mapping automatically e.g.

import wx

keyMap = {}
for varName in vars(wx):
    if varName.startswith("WXK_"):
        keyMap[varName] = getattr(wx, varName)

print keyMap

然后在OnChar中，您可以执行此操作

Then in OnChar you can just do this

def OnChar(self, evt):
    try:
        print keyMap[evt.GetKeyCode()]
    except KeyError:
        print "keycode",evt.GetKeyCode(), "not found"
