Added helper class wxCArrayString, better replacement for wxArrayString::GetStringArray. Added overloaded constructors and Create() methods taking a wxArrayString for wxCheckListBox, wxChoice, wxComboBox, wxListBox, wxRadioBox, wxSingleChoiceDialog, wxMultipleChoiceDialog. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@25440 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
