如何连接虚拟键以便它们打印到顶部的文本字段？

Question

我设置了希伯来语键盘的格式，但不知道如何让按键工作，以便您键入的内容显示在顶部的文本字段中。”“键盘”包含每个键的功能。理论上应该调用它来打印每个键。可能有一个更有效的方法来做这件事，但这是我的第一个图形用户界面，所以我真的不知道该怎么做，也找不到一个在线解决方案，适合这种情况具体。你知道吗

    import wx
    calc=wx.App()
    win=wx.Frame(None, title='gematria calculator', size=(1400,700), pos=(0,0))
    import keyboard  #contains functions for each key (eg- keyboard.aleph() should print letter aleph to the text field)

    textfield=wx.TextCtrl(win, pos=(50,25), size=(1100,150))   #where everything should print to
    enter=wx.Button(win, label='enter', pos=(1175,25), size=(200,150))

如果不确切知道keyboard模块中的函数做什么，很难回答，但我假设它们只是将相应的符号附加到文本字段中。你知道吗

有这么多相似的按钮，对每个键使用wx id可能是最简单的，并且避免了创建许多相似的变量和函数的繁琐。类似地，如果keyboard模块中的每个函数所做的事情几乎相同，那么也可以将其分解出来。你知道吗

因此，最简单的方法可能是将所有键盘信息放在一个配置“变量”中，并在构建控件时对其进行迭代。你知道吗

注意，代码中的dictionarykeyboard_controls同时存储函数名和要添加的文本，但您只需要其中一个，这取决于哪个更合适。你知道吗

您可能希望捕获EVT\u KEY\u并在该事件处理程序中进行字符串替换。所以当你抓到一个字母时，你把它翻译成合适的希伯来语字符，然后做如下操作：

self.myTextCtrl.AppendText(someHebrewLetter)
