title: Custom controls in wxformbuilder
body: <p>I am currently having a issue with TextCtrlAutoComplete (<a href="https://wiki.wxpython.org/TextCtrlAutoComplete" rel="nofollow">https://wiki.wxpython.org/TextCtrlAutoComplete</a>) and wxFormBuilder.</p>
  
  <p>I would like to use the Autocomplete version but i have no way of telling wxFormbuilder to use a custom control as far as i can find. </p>
  
  <p>How can i make it so it correctly generates the class. Or how to i correctly override the member in a subclass?</p>
  
  <p>I also have problem with a workaround:</p>
  
  <p>I have a few wxBoxsizers nested. I now have a TextCtrl as a place holder i would like to replace. </p>
  
  <p>If i do :</p>
  
  <pre><code>self.m_textCtrlAlias = TextCtrlAutoComplete(self, [wx.ID_ANY, wx.EmptyString, wx.DefaultPosition, wx.DefaultSize, 0], colSearch=True,choices=['example', 'hello', 'world', 'foo', 'bar'])
  </code></pre>
  
  <p>The control ends up in the upper left corner of the form. If there any way to replace the other control. I used wxBoxSizer in the master class there also not set as a member. </p>
  
  <p>Anyone has more suggestions i am open to do it.</p>
