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.
