Talk to a MySQL database via the GUI ? Perform unit-testing and internationalizing the GUI ? Extend the GUI with third-party graphical libraries ? Get to know the best practices to create GUIs In Detail Python is a multi-domain, interpreted programming language. It is a widely used general-purpose, high-level programming language. It is often used as a *ing language because of its forgiving syntax and compatibility with a wide variety of different eco-systems. Python GUI Programming Cookbook follows a task-based approach to help you create beautiful and very effective GUIs with the least amount of code necessary. This book will guide you through the very basics of creating a fully functional GUI in Python with only a few lines of code. Each and every recipe adds more widgets to the GUIs we are creating. While the cookbook recipes all stand on their own, there is a common theme running through all of them. As our GUIs keep expanding, using more and more widgets, we start to talk to networks, databases, and graphical libraries that greatly enhance our GUI’s functionality. This book is what you need to expand your knowledge on the subject of GUIs, and make sure you’re not missing out in the long run. Style and approach This programming cookbook consists of standalone recipes, and this approach makes it unique.. While each recipe explains a certain concept, throughout the book you’ll build a more and more advanced GUI, recipe after recipe. In some of the advanced topics, we simply create a new GUI in order to explore these topics in depth.

A definitive natural history of the Yorkshire Dales, covering the range of wildlife habitats, rich cultural heritage and ecological history of one of our best-loved National Parks. The Yorkshire Dales National Park is a special place: its outstanding scenery and the diversity of habitats is perhaps unrivalled in any other National Park in Britain. This rich biodiversity has been a great attraction to naturalists for over two centuries. But to fully appreciate the present-day plant and animal communities, their status and the constraints upon them, it is important to understand the geology and landscape history of the National Park, including the role that human populations have played in modifying the environment. In this long-anticipated New Naturalist volume, John Lee introduces the National Park, exploring both its geology and geomorphology, and describing the role of early naturalists and the Yorkshire Naturalists Union in recording and understanding the natural history of the Dales. He describes the major habitats or groups of habitats which underline the ecological importance of the Dales. Lee covers the earliest settlement times to the modern day, and he focuses in particular on the most iconic plant of the Dales, the Lady’s Slipper Orchid, arguably the rarest of native British plants, which until recently was thought to be confined to a single plant in the Dales. Lee takes a historical approach, describing its near eradication and early attempts to conserve it – including the establishment of a secret society – concluding with recent scientific conservation approaches.

A fresh, witty, accessible life of Queen Victoria. Not since Lytton Strachey has the irony, contradictions and influence of this Queen been treated with such flourish or biographical insight. 'Queen Victoria had a very complicated and psychologically fascinating personality and only a very talented biographer could get to the key of her character. Fortunately in Matthew Dennison's pithy, well-researched, beautifully written and very accessible book, she has found one' Andrew Roberts Queen Victoria is Britain’s queen of contradictions. In her combination of deep sentimentality and bombast; cultural imperialism and imperial compassion; fear of intellectualism and excitement at technology; romanticism and prudishness, she became a spirit of the age to which she gave her name. Victoria embraced photography, railway travel and modern art; she resisted compulsory education for the working classes, recommended for a leading women’s rights campaigner ‘a good whipping’ and detested smoking. She may or may not have been amused. Meanwhile she reinvented the monarchy and wrestled with personal reinvention. She lived in the shadow of her mother and then under the tutelage of her husband; finally she embraced self-reliance during her long widowhood. Fresh, witty and accessible, Queen Victoria is a compelling assessment of Victoria’s mercurial character and impact, written with the irony, flourish and insight that this Queen and her rule so richly deserve.
