Troll Tech is proud to relase a free beta-version of Qt (pronounced: "cute")
for X-Windows/Linux.

Qt is an object-oriented framework for developing graphical user interface

The documentation can be browsed on the web at http://www.troll.no/
where you will also find other Qt-related links.

It is ftp'able from sunsite.unc.edu in /pub/Linux/Incoming, hopefully
soon /pub/Linux/devel/c++.  Here is the LSM entry:

Title:          Qt toolkit
Version:        0.90
Entered-date:   20may95
Description:    C++ GUI class library with Motif look and feel
Keywords:       gui library motif
Author:         qt-bugs@troll.no
Maintained-by:  qt-buts@troll.no
Primary-site:   sunsite.unc.edu /pub/Linux/devel/c++
Platform:       linux/X11R6
Copying-policy: freely distributable with certain restrictions

About Qt:

Qt consists of a rich C++ library (around 100 classes) and a meta-object
system that extends C++ with new concepts called signals and slots.
Signals and slots define clean and natural object interfaces for creating
independent objects.
This makes Qt very suitable for true component programming.

A "hello world" application under Qt is only 8 lines of C++ code:

    #include <qmsgbox.h>
    #include <qapp.h>

    int main( int argc, char **argv )
        QApplication a( argc, argv );
        return QMessageBox::message( "Attention", "Hello, world!" );

Qt dramatically cuts down on development time and complexity in
writing user interface software for X-Windows/Linux.
It allows the programmer to focus directly on the programming task,
and not mess around with low-level X11 code.

Qt is very fast and compact because it is based direcly on Xlib and not
Motif or X Intrinsics.
Qt's widgets (user interface objects) emulate Motif look and feel.

Qt supports advanced features such as drawing transformed graphics,
including drawing rotated text and pixmaps.
Pixmaps can be loaded and saved using several image formats.
An image class makes it easy to implement image processing algorithm.

Qt is definitely not a toy. It is a professional product that compares
well to any commercial GUI class library.

If you find any bugs, send a report to qt-bugs@troll.no.
