如何在Cocoa Mac Os X应用程序的NSTableView中为用户提供快速浏览体验？

Question

I work with some files in a NSTableView in my Desktop Application, and I would like to react to space bar keyboard shortcuts by providing a quickly experience for various kinds of files. Is there any snippet available anywhere that can point me in the right direction ?

Thanks for any help... !

Answer 1

You can use QLPreviewPanel for this. It's a subclass of NSPanel and NSWindow , so you can use -orderFront: to show it.

Your controller class should implement the methods of the QLPreviewPanelController informal protocol to declare that it can control a Quick Look preview panel and to be notified that it is the controller.

When it is the controller, it can set the panel's delegate and/or data source. It would implement the methods of the respective protocols to provide the items to preview.

Apple provides the QuickLookDownloader sample project to demonstrate its use.
