Threading Programming Guide > Thread Safety Summary > NSView Restrictions: "The NSView class is generally thread-safe, with a few exceptions. You should create, destroy, resize, move, and perform other operations on NSView objects only from the main thread of an application. Drawing from secondary threads is thread-safe as long as you bracket drawing calls with calls to lockFocusIfCanDraw and unlockFocus." You are not drawing, so what you are doing falls under "other operations." > Also, is it thread-safe to bracket the sizeToFit method between > lockFocusIfCanDraw and unlockFocus, rather than performing the > resizing on the main thread? -sizeToFit is not a drawing method. It's unclear why you think -lockFocusIfCanDraw will help here. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
