X11Blocks Description

X11Blocks package is an Objective-C Block oriented X Window System Toolkit. X11Blocks package is an Objective-C Block oriented X Window System Toolkit.X11Blocks is a layer above "Xlib" (version 11) and provides functionality that is similar to the "Xt" (X Intrinsics) and Xaw widget libraries.Whereas much of the X Intrinsics is dedicated to implementing a classing system in C, X11Blocks uses Objective-C (an extension of C) for this purpose.X11Blocks makes extensive use of Objective-C "Blocks", where Blocks play a role similar to 'callbacks' in the Intrinsics.Objective-C Blocks, also known as Block closures or Action Expressions, are pieces of code represented by instances of an Objective-C class (called Block) for delayed evaluation.For example, the action in a "MenuItem" object is a Block.Blocks are useful for "event-based" programming and offer a significant advantage over "callbacks" in that Blocks can refer to and alter the context in which a Block was created.
