Available in PDF, EPUB and Kindle. Book excerpt: Master Qt’s Most Powerful APIs, Patterns, and Development Practices Qt has evolved into a remarkably powerful solution for cross-platform desktop, Web, and mobile development. However, even the most experienced Qt programmers only use a fraction of its capabilities. Moreover, practical information about Qt’s newest features has been scarce—until now. Advanced Qt Programming shows developers exactly how to take full advantage of Qt 4.5’s and Qt 4.6’s most valuable new APIs, application patterns, and development practices. Authored by Qt expert Mark Summerfield, this book concentrates on techniques that offer the most power and flexibility with the least added complexity. Summerfield focuses especially on model/view and graphics/view programming, hybrid desktop/Web applications, threading, and applications incorporating media and rich text. Throughout, he presents realistic, downloadable code examples, all tested on Windows, Mac OS X, and Linux using Qt 4.6 (and most tested on Qt 4.5) and designed to anticipate future versions of Qt. The book Walks through using Qt with WebKit to create innovative hybrid desktop/Internet applications Shows how to use the Phonon framework to build powerful multimedia applications Presents state-of-the-art techniques for using model/view table and tree models, QStandardItemModels, delegates, and views, and for creating custom table and tree models, delegates, and views Explains how to write more effective threaded programs with the QtConcurrent module and with the QThread class Includes detailed coverage of creating rich text editors and documents Thoroughly covers graphics/view programming: architecture, windows, widgets, layouts, scenes, and more Introduces Qt 4.6’s powerful animation and state machine frameworks

Available in PDF, EPUB and Kindle. Book excerpt: The popular open source KDE desktop environment for Unix was built with Qt, a C++ class library for writing GUI applications that run on Unix, Linux, Windows 95/98, Windows 2000, and Windows NT platforms. Qt emulates the look and feel of Motif, but is much easier to use. Best of all, after you have written an application with Qt, all you have to do is recompile it to have a version that works on Windows. Qt also emulates the look and feel of Windows, so your users get native-looking interfaces.Platform independence is not the only benefit. Qt is flexible and highly optimized. You'll find that you need to write very little, if any, platform-dependent code because Qt already has what you need. And Qt is free for open source and Linux development.Although programming with Qt is straightforward and feels natural once you get the hang of it, the learning curve can be steep. Qt comes with excellent reference documentation, but beginners often find the included tutorial is not enough to really get started with Qt. That's whereProgramming with Qt steps in. You'll learn how to program in Qt as the book guides you through the steps of writing a simple paint application. Exercises with fully worked out answers help you deepen your understanding of the topics. The book presents all of the GUI elements in Qt, along with advice about when and how to use them, so you can make full use of the toolkit. For seasoned Qt programmers, there's also lots of information on advanced 2D transformations, drag-and-drop, writing custom image file filters, networking with the new Qt Network Extension, XML processing, Unicode handling, and more.Programming with Qt helps you get the most out of this powerful, easy-to-use, cross-platform toolkit. It's been completely updated for Qt Version 3.0 and includes entirely new information on rich text, Unicode/double byte characters, internationalization, and network programming.

Book excerpt: From the north woods of Maine to the cactus-filled deserts of Arizona, America's national monuments include vast lands rivaling the national parks in beauty, diversity, and historical heritage. These critically important landscapes, mostly under the Bureau of Land Management supervision, are often under the radar with limited visitor information available yet offer considerable opportunities for solitude and adventure compared to bustling national parks. The Antiquities Act of 1906 gave Presidents the authority to proclaim national monuments as an expedited way to protect areas of natural or cultural significance. Since then, 16 Presidents have used the Antiquities Act to preserve some of America's most treasured public lands and waters. In 2017, an unprecedented Executive Order was issued questioning these designations by calling for the review of 27 national monuments across 11 states and two oceans, opening the threat of development to vulnerable and irreplaceable natural resources. Our National Monuments introduces these spectacular and unique landscapes, in the first book of its kind. Accompanying the collection of scenic photographs is an invaluable guide including maps of each national monument with carefully selected attractions identified and described based on the author's wide-ranging explorations. Our National Monuments invites readers to experience for themselves these lands and learn about the people and cultures who came before, and to whom these lands are still sacred places. QT Luong is one of the most prolific photographers working in America's public lands and the author of Treasured Lands, the best-selling and acclaimed photography book about the national parks. Combining hundreds of his sumptuously printed photographs with essays from citizen conservation associations caring for these national treasures; including a foreword by former Secretary of the Interior Sally Jewell and photographs of marine national monuments from Ansel Adams award-winning photographer Ian Shive, the comprehensive portrayals of Our National Monuments help readers understand how these essential landscapes are preserving America's past and shaping its future.

Book excerpt: Open source software finds its connections with free software and is part of free and open source software over the extended term. Open-source software (OSS) is a form of computer software program that releases source code under a licensing legitimacy wherein the copyright holder allows users the privilege to analyze, modify and share the software to anyone and for any productive purpose. Open-source software may be created either freely and collaboratively. Open-source software is a case in point of open collaboration. The progress of open-source software will offer assorted perspectives beyond those of a single enterprise A 2008 study from the Standish Group reported that the implementation of open-source software models culminated in savings for customers of around $60 billion (£ 48 billion) annually. Initiatives of open source software are undertaken and managed by a network of voluntary programming associations and are commonly used in the gamut of both free and commercial outputs.

This book was released on 1997-12-08 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The long QT syndrome has become the focus of considerable scientific attention in recent years because of the discovery of several genes responsible for its development. These discoveries have demonstrated the genetic heterogeneity of the syndrome and have given both the clinician and researcher the opportunity to relate phenotypic variants to different genotypes responsible for distinctly different ion channel abnormalities. These analyses - which are comprehensively reviewed and explored here for the first time - are now beginning to suggest treatment strategies specific to each genotype. The full power of such precise diagnosis promises highly targeted and very successful therapy. In the author's own words, there is "the progressive realization that behind the surface of an infrequent disease may lie the key to understanding the mechanisms by which modulation of autonomic function may enhance or prevent the occurrence of life-threatening arrhythmias." The aim of the Clinical Approaches to Tachyarryhthmias series is to update the physician, cardiologist, and all those responsible for the the care of patients with cardiac arrhythmias. In this volume, one of the foremost research pioneers in the field provides a clear and comprehensively considered account of this syndrome's history, significance, and exciting current status. Readers will gain a better understanding of why the long QT syndrome has been the focus for numerous theories of arrhythmogenesis, why it has been the test bed for many antiarrhythmic treatments, and why it remains the paradigm for the diagnosis and management of cardiac arrhythmias.
