title: Python WX - Returning user input from wx Dialog
body: <p>I'm new to Python and WX. I created a simple test dialog shown below that prompts the user with a combobox. I would like to capture the value from the combox in my main program. How do I call it from my main program? </p>
  
  <p>This is how I was purposing to call it that displays the dialog but does not currently capture the value from the combobox:</p>
  
  <pre><code>    import highlight
      highlight.create(self).Show(True)
      a = highlight.OnComboBox1Combobox(self)
      print a
  </code></pre>
  
  <p>The name of the Dialog file is "highlight". Below is the code:</p>
  
  <pre><code>#Boa:Dialog:Dialog2
  
  import wx
  
  def create(parent):
      return Dialog2(parent)
  
  [wxID_DIALOG2, wxID_DIALOG2COMBOBOX1, wxID_DIALOG2STATICTEXT1, 
  ] = [wx.NewId() for _init_ctrls in range(3)]
  
  class Dialog2(wx.Dialog):
      def _init_ctrls(self, prnt):
          # generated method, don't edit
          wx.Dialog.__init__(self, id=wxID_DIALOG2, name='', parent=prnt,
                pos=wx.Point(264, 140), size=wx.Size(400, 485),
                style=wx.DEFAULT_DIALOG_STYLE, title='Dialog2')
          self.SetClientSize(wx.Size(384, 447))
  
          self.comboBox1 = wx.ComboBox(choices=['test1', 'test2'],
                id=wxID_DIALOG2COMBOBOX1, name='comboBox1', parent=self,

          self.comboBox1.SetToolTipString(u'comboBox1')

                16), size=wx.Size(19, 13), style=0)
