Thread-safe GUI updates

I'm working on a project that uses multiple threads that signal the
GUI for various UI updates.  The best way I've read to do this is to
post an event to the main window's event queue and process it on the
main thread.  It looks like AddPendingEvent or ProcessEvent would be
likely candidates for doing this.

Upon inspection, however, both take a wx.Event parameter that has a
single constructor with an IntPtr.  Is this the correct way to do
this?  I would imagine one would derive a class from wx.Event and pass
in the custom class.  Has anyone else solved this issue?
