title: How to make wx.TextEntryDialog larger and resizable
body: <p>I create a <a href="http://www.wxpython.org/docs/api/wx.TextEntryDialog-class.html" rel="noreferrer"><code>wx.TextEntryDialog</code></a> as follows:</p>
  
  <pre><code>import wx
  
  dlg = wx.TextEntryDialog(self, 'Rules:', 'Edit rules', 
                           style=wx.TE_MULTILINE|wx.OK|wx.CANCEL)
  dlg.SetValue(self.rules_text.Value)
  if dlg.ShowModal() == wx.ID_OK:
      …
  </code></pre>
  
  <p>This results in a dialog box that is too small for my needs, and that is not resizable:</p>

  <p>My question is: <strong>How can I make the dialog box larger and resizable?</strong>  I tried adding the flags <code>wx.DEFAULT_DIALOG_STYLE</code> and <code>wx.RESIZE_BORDER</code>, but that had no effect except to replace the text with dots:</p>
  
  <pre><code>dlg = wx.TextEntryDialog(self, 'Rules:', 'Edit rules', 
                           style=wx.TE_MULTILINE|wx.OK|wx.CANCEL|wx.DEFAULT_DIALOG_STYLE|wx.RESIZE_BORDER)
  </code></pre>
