QUrlOperator op.copy()
Message 1 in thread
Hello list,
Thank's to documentation examples, I can download a BMP picture file to
disk using QUrlOperator op.copy() and FTP protocol.
But I am still far away from what I need to accomplish as that picture
should never be copied to disk but to memory - then displayed as a
preview using a QWidget item in a QDialog.
So the first question is: how do we download data to memory instead of file?
And the next question is: how do we display picture data just downloaded
to memory (as a QByteArray I suppose) to a QWidget item?
Thank's in advance for any help.
Best regards
Patrick Perroud
