Why are you using a separate thread when you already do the downloading in
a separate process? QProcess allows to run the process asynchronously and
get notified when the process is done, there's no reason to run that in a
separate thread.

MyCustomEvent ev;
QApplication::postEvent( ev, obj1 );

then in obj1 class you need to catch the event and act accordingly (i.e.
update your gui).

But again, so far your description doesn't indicate any reason to use a
separate thread.
