See http://developer.apple.com/mac/library/DOCUMENTATION/Quartz/Reference/QLPrev... and /System/Library/Frameworks/Quartz.framework/Versions/A/Frameworks/QuickLookUI.framework/Versions/A/Headers/QLPreviewPanel.h on your computer. If it were a private API, it wouldn't have a page in the docs and it's header would be in PrivateFrameworks, is that right? -- Ticket URL: <http://www.macruby.org/trac/ticket/655#comment:2> MacRuby <http://macruby.org/>

Problem #1: there is no BridgeSupport file for QuickLookUI. Problem #2: I suspect the metadata generator doesn't know how to parse the new @protocol syntax (with @required). Unfortunately this isn't something we can fix in MacRuby itself. These bugs need to be reported to Apple so that they can be fixed in a future version of Mac OS X. However, a workaround could be to write by hand a bridgesupport file that contains the description of these datasource methods. -- Ticket URL: <http://www.macruby.org/trac/ticket/655#comment:8> MacRuby <http://macruby.org/>

Do you have any idea what may be causing the other issue (image not found after update to MacRuby 0.6) ? -- Ticket URL: <http://www.macruby.org/trac/ticket/655#comment:10> MacRuby <http://macruby.org/>

And I have a new problem - I was just about to upload a new release of my app, when I noticed that QuickLook doesn't work in the final version. Apparently, once I get through the compile step (macruby_deploy --compile build/Release/my.app), the same problem reappears - previewItemAtIndex: gets called with nil instead of 0... My QLPreviewPanel.bridgesupport file is still included in the bundle, and it gets loaded during startup, but it doesn't seem to have any effect. A moment earlier, before I compile the ruby files, the same app bundle works as intended. Any ideas?... -- Ticket URL: <http://www.macruby.org/trac/ticket/655#comment:12> MacRuby <http://macruby.org/>

I did check and in fact, protocols are not yet supported. Otherwise, I don't know where you loaded the bridge support file, but a good place to do it could be: {{{ #!ruby # Loading the Cocoa framework. If you need to load more frameworks, you can # do that here too. framework 'Cocoa' load_bridge_support_file NSBundle.mainBundle.pathForResource("QLPreviewPanel", ofType:"bridgesupport") }}} (this assumes you placed the `.bridgesupport` file in the `Resources` directory) Other than that, after investigation, you can safely ignore the warnings, they will not affect your application and should disappear one day :-). -- Ticket URL: <http://www.macruby.org/trac/ticket/655#comment:14> MacRuby <http://macruby.org/>

The images do not exist and the class itself is not used anymore (it's dead code). The warnings do not appear in a pure ObjC app since the class is not used. However, at runtime, MacRuby parses all the classes and it looks like +initialize got triggered for that specific class. A bug has been filed against the quicklook component internally :-) -- Ticket URL: <http://www.macruby.org/trac/ticket/655#comment:18> MacRuby <http://macruby.org/>
