Ah, appending, sorry, I misunderstood. Yes, that would do it.

If you do:

textctrl.GetBuffer().Invalidate(wxRICHTEXT_ALL);
textctrl.Refresh();

it should lay the content out correctly, followed optionally by:

textctrl.Update();

if you need the control to be laid out correctly immediately after the 
refresh (e.g. for hit-testing purposes).
