What are system frameworks, and why should you care? 2. Brief overview of the frameworks, classes, and APIs that will be demonstrated. 3. Demo 1: PyObjC 4. Demo 2: Objective-C 5. Wrap up and questions. 4 What’s a System Framework? …and why should you care? (OS X) system frameworks provide interfaces you need to write software for the Mac. Many of these are useful for Mac admins creating: • scripts • GUI applications • command-line tools Learning about system frameworks will teach you more about OS X, which will probably make you a better admin. 5 Frameworks, Classes, and APIs oh my! Cocoa CoreFoundation • Foundation • CFPreferences - NSFileManager CoreGraphics - NSTask • Quartz - NSURLSession - NSUserDefaults • AppKit - NSApplication 6 CoreFoundation CoreFoundation is a C framework that knows about Objective-C objects. Some parts of CoreFoundation are written in Objective-C. • Other parts are written in C. CoreFoundation uses the CF class prefix, and it provides CFString, CFDictionary, CFPreferences, and the like. Some Objective-C objects are really CF types behind the scenes. -
User Interface Software Tools
User Interface Software Tools Brad A. Myers August 1994 CMU-CS-94-182 School of Computer Science Carnegie Mellon University Pittsburgh, PA 15213 Also appears as Human-Computer Interaction Institute Technical Report CMU-HCII-94-107 This report supersedes CMU-CS-92-114 from February, 1992, published as: Brad A. Myers. ‘‘State of the Art in User Interface Software Tools,’’ Advances in Human- Computer Interaction, Volume 4. Edited by H. Rex Hartson and Deborah Hix. Norwood, NJ: Ablex Publishing, 1993. pp. 110-150. Abstract Almost as long as there have been user interfaces, there have been special software systems and tools to help design and implement the user interface software. Many of these tools have demonstrated significant productivity gains for programmers, and have become important commercial products. Others have proven less successful at supporting the kinds of user interfaces people want to build. This article discusses the different kinds of user interface software tools, and investigates why some approaches have worked and others have not. Many examples of commercial and research systems are included. Finally, current research directions and open issues in the field are discussed. This research was sponsored by NCCOSC under Contract No. N66001-94-C-6037, ARPA Order No. B326.

Programming Java for OS X
Programming Java for OS X hat’s so different about Java on a Mac? Pure Java applica- tions run on any operating system that supports Java. W Popular Java tools run on OS X. From the developer’s point of view, Java is Java, no matter where it runs. Users do not agree. To an OS X user, pure Java applications that ignore the feel and features of OS X are less desirable, meaning the customers will take their money elsewhere. Fewer sales translates into unhappy managers and all the awkwardness that follows. In this book, I show how to build GUIs that feel and behave like OS X users expect them to behave. I explain development tools and libraries found on the Mac. I explore bundling of Java applications for deployment on OS X. I also discuss interfacing Java with other languages commonly used on the Mac. This chapter is about the background and basics of Java develop- ment on OS X. I explain the history of Java development. I show you around Apple’s developer Web site. Finally, I go over the IDEs commonly used for Java development on the Mac. In This Chapter Reviewing Apple Java History Exploring the history of Apple embraced Java technologies long before the first version of Java on Apple computers OS X graced a blue and white Mac tower. Refugees from the old Installing developer tan Macs of the 1990s may vaguely remember using what was tools on OS X called the MRJ when their PC counterparts were busy using JVMs. Looking at the MRJ stands for Mac OS Runtime for Java. -

The GNOME Desktop Environment
The GNOME desktop environment Miguel de Icaza ([email protected]) Instituto de Ciencias Nucleares, UNAM Elliot Lee ([email protected]) Federico Mena ([email protected]) Instituto de Ciencias Nucleares, UNAM Tom Tromey ([email protected]) April 27, 1998 Abstract We present an overview of the free GNU Network Object Model Environment (GNOME). GNOME is a suite of X11 GUI applications that provides joy to users and hackers alike. It has been designed for extensibility and automation by using CORBA and scripting languages throughout the code. GNOME is licensed under the terms of the GNU GPL and the GNU LGPL and has been developed on the Internet by a loosely-coupled team of programmers. 1 Motivation Free operating systems1 are excellent at providing server-class services, and so are often the ideal choice for a server machine. However, the lack of a consistent user interface and of consumer-targeted applications has prevented free operating systems from reaching the vast majority of users — the desktop users. As such, the benefits of free software have only been enjoyed by the technically savvy computer user community. Most users are still locked into proprietary solutions for their desktop environments. By using GNOME, free operating systems will have a complete, user-friendly desktop which will provide users with powerful and easy-to-use graphical applications. Many people have suggested that the cause for the lack of free user-oriented appli- cations is that these do not provide enough excitement to hackers, as opposed to system- level programming. Since most of the GNOME code had to be written by hackers, we kept them happy: the magic recipe here is to design GNOME around an adrenaline response by trying to use exciting models and ideas in the applications. -

Development Environment for the Raspberry Pi Using a Cross Compiling Toolchain and Eclipse | Hertaville 07.10.13 13:37
Development Environment for the Raspberry Pi using a Cross Compiling Toolchain and Eclipse | Hertaville 07.10.13 13:37 Hertaville Welcome to Hertaville! Development Environment for the Raspberry Pi using a Cross Compiling Toolchain and Eclipse Posted on September 28, 2012 by halherta UPDATED July 15th 2013 In this blog entry the setup of a cross-compiling development environment for the Raspberry Pi will be demonstrated. This will include the Official Raspbian (armhf) cross compiling toolchain (available from github) Eclipse for C/C++ Developers (Linux) We will finally write a simple Hello World program on our development PC, compile it using the cross compiler and then deploy it onto our Raspberry Pi board to run it. I’m going to assume that you have already installed a Raspbian Wheezy image on your RPi board and that you have Linux installed on your desktop PC. For this tutorial I am using the Crunchbang 11 Linux OS (64-bit) on my PC. The instructions provided should work on most Debian/Ubuntu based Linux distributions running directly on a PC or as a a guest operating system via VMWare/ VirtualBox . A remote debugging tutorial; which I consider to be the continuation of this tutorial, can be found here. Finally, Derek Molloy has a great video tutorial on setting up a similar environment for the Beaglebone. Watching this video was incredibly informative and helped me set up this tutorial. So what is a cross compiling toolchain and why use one ? A native compiler such as the default gcc tool on the PC is a compiler that runs on an Intel machine, as well as creates binaries intended to be run on an Intel machine. -
Drawing in GTK+
CSci493.70 Graphical User Interface Programming Prof. Stewart Weiss Drawing in GTK+ Drawing in GTK+ Background In order to understand how to draw in GTK, you rst have to understand something about how GTK draws widgets, because how GTK draws widgets has an important role in how you design your drawing application. An understanding of how GTK draws widgets is also required if you ever plan to build your own custom widgets. Windows and Clipping Most windowing systems are designed around the idea that an application's visual display lies within a rectangular region on the screen called its window. The windowing system, e.g. Gnome or KDE or Explorer, does not automatically save the graphical content of an application's windows; instead it asks the application itself to repaint 1 its windows whenever it is needed. For example, if a window that is stacked below other windows gets raised to the top, then a client program has to repaint the area that was previously obscured. When the windowing system asks a client program to redraw part of a window, it sends an exposure event to the program that contains that window. An exposure event is simply an event sent from the underlying windowing system to a widget to notify it that it must redraw itself. In this context, a "window" means "a rectangular region with automatic clipping", not a top-level application window. Clipping is the act of removing portions of a window that do not need to be redrawn, or looked at the other way, it is determining which are the only regions of a window that must be redrawn.
