You cannot create or modify GUI elements from any other thread than
the main one. This is a restriction of both the GTK and MSW gui libs
that wxWidgets wraps.
I have not used LUA-AIO, but if you can send a signal to the main
thread to update the GUI that could work. This is typically done by
calling wxEvtHandler::AddPendingEvent(wxEvent). Note that wxWindow is
derived from the wxEvtHandler class so you can use the main wxFrame to
handle these delayed messages. The wxEvent you send will be some
"fake" event, maybe a generic wxCommandEvent of type
wxEVT_COMMAND_BUTTON_CLICKED (or whatever) with a unique id and
perhaps the command you want to implement as the string member.
Hope this helps,
John
