[vlc-devel] Ticket #5730 - how to access playlist items

[zemanm17 at fel.cvut.cz]

I've started my work on  Ticket #5730. So far I've managed to create the GUI element (a button) that is going to perform
the shuffle.

Now, I'm struggling with accessing the playlist elements themselves. My method void StandardPLPanel::shufflePlaylist() resides
in standardpanel.cpp. I've tried this:

FOREACH_ARRAY( playlist_item_t *p_del, THEPL->all_items )
	        free( p_del->pp_children );
	        vlc_gc_decref( p_del->p_input );
	        free( p_del );
 FOREACH_END();

I know this is used to destroy the list, but I needed verify somehow that I'm able to access the playlist items. However, it doesn't
do anything. 

Could anyone show me how to iterate through playlist items? 

Thanks,

Martin
