Re: Fastest high-quality thumbnail display

If you want to display many thumbnails (or images in general) why not use the ImageKit? It’s what it was designed for. Check out IK* files. “The IKImageBrowserView class is a view for displaying and browsing a large amount of images and movies efficiently.” On Jul 25, 2011, at 3:04 PM, James

You asked something similar back in March http://www.cocoabuilder.com/archive/cocoa/300383-iphone-animation-puzzle.html I think the answer is still UIViewAnimationOptionAllowUserInteraction. Don't know why changing to Lion would have made a difference however as I think that option has been off

Telling Auto Save, "No, I'm busy now"

With Auto Save enabled in a document, I find that Lion sometimes wants to break into a sequence of operations to do an Auto Save. I haven't been able to find any recommendation of how to tell Auto Save "No, I'm busy now". I just figured out how to do it by overriding saveToURL. It seems t

Thanks for that suggestion Martin - I hadn't thought of looking at parent window. I kind of think that is an implementation detail behind the scenes that we shouldn't have to worry about in our code, so will file a bug report about it as Corbin suggested, and hopefully it will either be made to

[Q] calling OpenMP functions in a thread function for NSThread?

Hello, I'm using a GraphicsMagick library in my project. However, there I found a very interesting behavior. If I create an instance of Magick::Image in a normal method, it works OK. However, if it is implemented in a thread function, it crashes when it calls omp_get_max_threads(). I tried t

Hi all, I have seen this issue come up a lot, but there isn't much information on how to receive unicode input in a NSView. (I know we are supposed to just type in a NSTextField but that is impossible in our situation where the app must run stand-alone and as a browser plugin). we used to call i
