QMediaPlayer - Reorganising a QListWidget after calling shuffle()

[Evilpaperclip]

Good evening all,
Let me first mention that I have only experienced Qt for a month or two, and haven't ever touched C++ before that, so any code I paste up will most likely be riddled with faults!

I've set myself the task of creating a media player and am nearing completion, bugfixing basically. I found the slot QMediaPlaylist::Shuffle() and fancied using it. The media shuffles perfectly fine, however, I can't work out how to update the ListWidget to show the newly shuffled list.

Any help in this matter would be greatly appreciated,

Thanks in advance,

Alex

I've also just picked up a "handleSessionEvent: serious error = -2147467262" error whilst trying to play .avi and .mkv files. Is there anyway to add the codecs into my program?
