You can certainly download in another thread in Qt. However, you 
are only allowed to have the widget classes in the main thread. 
Qt is a large library that also spans non-GUI functionality and 
these can often be moved to separate threads, IO for example.

In this case you could download in a separate thread, then send 
signals to the progress bar object to update it. Is it possible 
to implement a similar approach in Gtk?
