setting wxCombobox background color on OS X

Hi,

I noticed that setting the background color for wxComboBox looks really ugly on OS X. The background color is set on the whole widget area, instead of the combobox’s text area (like it is done on Windows). Here is how they look on OS X: http://snag.gy/b4mOS.jpg

I googled and found this old thread from 2009 stating the reason behind this is that on OS X the combobox is actually a collection of controls and that I should use a workaround: http://markmail.org/message/76u57up3le7pfebr#query:+page:1+mid:pidrssf4mo36cjb2+state:results

However, when I call myComboBox.GetChildren(), nothing gets returned, so it has no children. Has this behavior changed somehow since 2009? How can I set the background color for the combobox’s text area only on OS X?

I am using wxPython 3.0.2.0 for Python 2.7
