Qt is a cross-platform C++ GUI application framework which provides application developers with all the functionality needed to build state-of-the-art graphical user interfaces. Since the commercial introduction of Qt in early 1996, Qt has formed the basis of many thousands of successful applications worldwide; it also forms the basis of KDE, the popular Open Source desktop environment.

Release Note: The Qt version 3.1 series is binary compatible with the 3.0.x series: applications compiled for 3.0 will continue to run with 3.1. Added Qt Script for Applications (a scripting engine, an IDE for creating and editing scripts and script forms and bindings to the Qt API); a Motif module (which replaces the Xt/Motif extension) for migrating to Qt with hybrid applications comprised of both Qt and Motif code; a toolbox for widgets (in place of the boolbars) in Qt Designer; support for rich text in Qt Designer; WYSIWYG support for QWidgetStack in Qt Designer; custom documentation set support to Qt Assistant (which can now be used by applications as a help browser); a full text search engine to Qt Assistant; a new format (LogText) to QTextEdit (performance and memory optimized especially designed for the fast display of large amounts of text, with support for basic highlighting); a QSyntaxHighlighter class for adding syntax highlighting capabilities to a QTextEdit; support for prepared query execution and value binding to the SQL classes (this enables writing large BLOBs to Oracle databases and Unicode strings to SQL servers); global strut support to QTableItem (and subclasses); support for binary datatypes to QTDSDriver; a new command line tool conv2ui to convert dialog description files from different file formats to .ui files; and an import filter for .kdevdlg files to Qt Designer. Improved Qt Designer signal / slot dialog, property editor and code editor; QAccel handling of shortcut clashes (a new signal activatedAmbiguously() is emitted in that case) and of multi-key sequences (e.g., Ctrl-X, Ctrl-F); the QHttp and QFtp classes (greater flexibility); QClipboard data exchange; thread support (almost all methods in the tools classes have been made reentrant and QApplication::postEvent() and a few other methods are now thread-safe); large file support (> 2GB); QDataTable to enable column swapping; QDockWindow docking behavior; QLineEdit (a lostFocus() signal and boundaries for clicking actions); and the Qt Designer action editor (sortable actions).
