Comment(by jakub.suder@…):

 I went to
 /System/Library/Frameworks/Quartz.framework/Frameworks/QuickLookUI.framework
 and called: gen_bridge_metadata -c "-IHeaders" Headers/QLPreviewPanel.h >
 ~/QLPreviewPanel.bridgesupport

 The result was:
 {{{
 <?xml version='1.0'?>

 </informal_protocol>
 </signatures>
 }}}

 So it looks like this was completely ignored:

 {{{
 @protocol QLPreviewPanelDataSource
 @required
 - (NSInteger)numberOfPreviewItemsInPreviewPanel:(QLPreviewPanel *)panel;
 - (id <QLPreviewItem>)previewPanel:(QLPreviewPanel *)panel
 previewItemAtIndex:(NSInteger)index;
 @end
 }}}
