Qt 2.0 introduces a wide range of major new features as well as
substantial improvements over the 1.x series. The documentation has
been significally extended and improved.
This file will only give an overview of the main changes since version
1.44. A complete list would simply be too large to be useful. For
more detail see the online documentation which is included in this
distribution, and also available on http://qt.nokia.com/doc/
The Qt version 2.x series is not binary compatible with the 1.x
series. This means programs compiled with Qt version 1.x must be
recompiled to work with Qt 2.0.
Qt 2.0 is mostly, but not completely, source compatible with Qt 1.x.
See the document "Porting from Qt 1.x to Qt 2.0" in the Online
Reference Documentation for information on how to port an existing Qt
1.x-based program to Qt 2.0. Note in particular the automatic porting
script included - it does a lot of the work for you.
As for 1.x, the API and functionality of Qt is completely portable
between Microsoft Windows and X11. And between Windows 95, 98 and NT:
Unlike most toolkits, Qt lets a single executable work on all three.
****************************************************************************
* New major features *
****************************************************************************
* Support for international software development:
QTranslator and the QObject::tr() function
QTextCodec (and subclasses)
QString is now a 16-bit Unicode string with good support for
legacy 8-bit interoperation. (The old 8-bit string class
from Qt 1.x has been renamed to QCString.)
QChar - a Unicode character
* Rich Text
QTextView - formatted text and images
QTextBrowser - navigate formatted text and images
QStyleSheet - define your own XML formatting tags
QSimpleRichText - display rich text anywhere
* Convenient and powerful new collection classes:
QMap<Key,Type> - QDict with arbitrary keys
QValueList<Type> - QList of types other than pointers
QStringList - QValueList<QString> with helper functions
* Dialogs
QColorDialog - user picks a color
QFontDialog - user picks a font
QWizard - framework for leading users through steps
* Layout
QGrid/QHBox/QVBox - grid and boxes of widgets automatically assembled
QHGroupBox/QVGroupBox - easy framed groups of widgets
QSizePolicy - a widget's abilities to change size in different ways
* Custom layouts
New, much simpler and more powerful API for creating custom layouts
* PNG Support
PNG support is now included in the core library
* Support for generalized configurable GUI styles:
QStyle and subclasses
* Session management
QSessionManager - saving state when the system shuts down
* Extended coordinate system
QPoint, QPointArray, QSize and QRect now have 32-bit coordinates
* Cleaner namespace
Global functions, enums and macros now either start with a 'q' or
have been moved into the new namespace class "Qt"
