The picker styles don't make sense for the button so we don't use them when creating the button but we do need to somehow use the style the picker was created with to create an appropriate dialog when it's clicked. Fix the problem by simply storing the style in a member variable and using it instead of wxWindow::m_windowStyle. Closes #11635. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@63654 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
