Simple example about g_file_copy and GFileProgressCallback with a progressbar ?

["Soulivanh Anothay" <sanothay gmail com>]

Hi all,

I have looked online but I could not find much helpful information.

Can anyone point me an simple example of using  GFileProgressCallback
with a progress bar to monitor g_file_copy.?

If possible working with multiple folders asynchronously.

Thanks,
