Programming with QT: Writing Portable GUI Applicat: Writing Portable GUI applications on UNIX and Win32: Write Portable GUI Applications on UNIX & Win32 Book

Programming with Qt offers an excellent introduction to the Qt toolkit, a powerful C++ graphical user interface (GUI) library that allows developers to create interfaces that run under both Unix and Windows. The book first looks at the strengths of the Qt library: it provides excellent cross-platform support, good performance, and ease of use for the C++ programmer. After a basic application, the book moves onto the event model in Qt, which uses signals and slots to attach events to code. The author demonstrates that Qt is a remarkably sophisticated user interface library. Early sections examine programming menus, including pop-up menus, basic widgets, or controls (such as labels and listboxes), and more complex controls (such as sliders, progress bars, listviews, and tables). Next the book presents material on Qt's built-in dialogs (for message boxes and opening and saving files) and layout managers. The author investigates Qt's container classes (such as arrays and dictionaries) and offers a lot of material on 2-D graphics, including printing, saving, and loading images. Later chapters look at validating text and working with files and directories, with tips on important topics such as focus handling, internationalization, portability, and debugging. (The author even shows you how to work with Qt in Perl and reviews several Qt GUI builders that help automate design.) Filled with expert advice and sample code, this guide makes a strong case that both Unix and Windows developers should try out Qt. --Richard DraganRead More

  • Product Description

    Qt is a C++ class library that lets you write GUI applications that run on UNIX, Windows 95/98, and Windows NT. Programming with Qt is much easier than programming with Motif, and more important, Qt applications are inherently portable. This indispensable guide explains all the features of Qt and teaches you how to take full advantage of this powerful, easy-to-use, cross-platform toolkit. While 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 tutorial isn't enough. That is where this book steps in. Programming with Qt guides you through the steps of writing a Qt application by showing you how to write a simple paint application. It presents all of the GUI elements in Qt, along with advice about when and how to use them, so that you can make full use of the toolkit. To help deepen your understanding, it includes exercises with completely worked out answers. There's also lots of information for seasoned Qt programmers, including material on advanced 2D transformations, drag-and-drop, and writing custom image file filters.
