No, that is not correct. As Martin already told you, which thread the
events are triggered in depends on which thread is calling Put() to begin
with. TIdFTP itself is not multi-threaded at all. The OnWork events are
triggered in the context of the same thread that calls Put(). If you are
calling Put() in the context of the main thread, then the event handlers can
safely access the GUI directly. If you are calling Put() in the context of
a worker thread instead, then you must synchronize access to the GUI.
