title: Is there any way to completely remove the focus border of a wxTextCtrl object on OSX?
body: <p>I am building a project in OSX (Yosemite) with wxWidgets 3.0.2.</p>
  <p>I can remove a blue border around the wxTextCtrl window by using wxBORDER_NONE. But when I put it in a sizer, it has a 3 pixel grey border that I just can't get rid of. What's the point of having 2 borders, one of which cannot be removed? Surely people want to customise more than that?</p>
  <p>Is there any possible way to remove it? I don't really want to hack at the wx source, but I will if I have to.</p>
  <p>Or is there another way of controlling layout without using sizers, than might cause the border not to appear?</p>

  <p>Update: It seems to be the focus highlight border. I don't want it.</p>

  <p>Is there any way of disabling the border around the focused UI object? It's so frustrating because it is such a minor thing, but my program is useless if can't remove it.</p>
