Qt 4.0 Beta 1 Released
======================

   Trolltech [http://www.trolltech.com/] has released the first Beta
version of the upcoming Qt 4.0. You can download it from
ftp.trolltech.com [ftp://ftp.trolltech.com/qt/source/] or from one of
its mirrors [http://www.trolltech.com/download/tech_previews.html]. An
updated online Qt Reference Documentation
[http://doc.trolltech.com/4.0/] is also available. The final Qt 4.0 is
expected to be released in late first quarter of 2005.

     There are five new technologies that are new to Qt, written
specifically for Qt 4:

    * Tulip [http://doc.trolltech.com/4.0/qt4-tulip.html], a new set of
      template container classes.
    * Interview [http://doc.trolltech.com/4.0/qt4-interview.html], a
      model/view architecture for item views.
    * Arthur [http://doc.trolltech.com/4.0/qt4-arthur.html], the Qt 4
      painting framework.
    * Scribe [http://doc.trolltech.com/4.0/qt4-scribe.html], the Unicode
      text renderer with a public API for performing low-level text
      layout.
    * Mainwindow [http://doc.trolltech.com/4.0/qt4-mainwindow.html], a
      modern action-based mainwindow, toolbar, menu, and docking
      architecture.

     This beta release also previews the new Qt Designer
[http://doc.trolltech.com/4.0/qt4-designer.html] user interface design
tool which is still heavily under development.
     In addition, the following modules have been significantly improved
since Qt 3:

    * A fully cross-platform accessibility
      [http://doc.trolltech.com/4.0/qt4-accessibility.html] module, with
      support for the emerging SP-API Unix standard in addition to
      Microsoft and Mac Accessibility.
    * The SQL module [http://doc.trolltech.com/4.0/qt4-sql.html], which
      is now based on the Interview model/view framework.
    * The network module
      [http://doc.trolltech.com/4.0/qt4-network.html], with better
      support for UDP and synchronous sockets.
    * The style API [http://doc.trolltech.com/4.0/qt4-styles.html],
      which is now decoupled from the widgets, meaning that you can draw
      any user interface element on any device (widget, pixmap, etc.).
    * Enhanced thread support
      [http://doc.trolltech.com/4.0/qt4-threads.html], with signal-slot
      connections across threads and per-thread event loops.

     Trolltech has set up a special mailing list, qt4-preview-feedback
[http://lists.trolltech.com/qt4-preview-feedback/], for discussion of
issues relating to the Qt 4 beta releases.
