wxTreeListCtrl - Alignment

Is it possible to allign headers of wxTreelistCtrl in one way and items in a different way.

e.g.:
col1 header = wxTL_ALIGN_CENTER
col1.item = wxTL_ALIGN_RIGHT

In the C++ source there is some reference to other.m_alignment, but I believe this is all part of InsertColumnInfo stuff, so maybe answers to my previous post will answer this too.

See you
