title: Show child wx.Frame?
body: <p>I've got two frames – mainWindow, which is the "primary" frame, and moreWindow, which is a child of mainWindow. I'd like to show moreWindow when a button in mainWindow is clicked. Here's what I'm trying:</p>
  
  <pre><code>def showChild(nil):
      moreWindow.Show()
  class mainWindow(wx.Frame):
      def __init__:
          buttonMore.Bind(wx.EVT_BUTTON, showChild)
  class moreWindow(wx.Frame):
  
  TypeError: unbound method Show() must be called with moreWindow instance as first argument (got nothing instead)
  </code></pre>
  
  <p>I tried using <code>moreWindow.Show(moreWindow)</code>, and that just gave a more cryptic error.</p>
