  Qt Toolkit - openSUSE
Qt is most notably used in the K Desktop Environment.
Qt 4 is dual-licensed under GPL and proprietary licenses on all supported platforms including Windows (while Qt/Windows 3.3 is only released under a proprietary license).
As KDE was based on Qt, many people in the open source and free software movements were worried that an essential piece of one of their major operating systems would be under commercial control.

 ONLamp.com -- Design Patterns in Qt   (Site not responding. Last check: 2007-09-10)
Qt is developed and marketed by the Norwegian company Trolltech and is available for Windows and various Unix dialects (and soon for the Macintosh).
Qt follows the single-source paradigm: A program written with Qt can be compiled and run on any of the supported platforms without changes to the source code.
In recent years, Qt has become famous for forming the base of the KDE desktop, a free desktop for Unix systems that now is the default graphical desktop on most Linux distributions.

 K Desktop Environment - History: The Qt Issue
The founding of the KDE Free Qt Foundation addresses and renders void fears by parts of the free software community that Qt one day may no longer be available for free software development or no longer be actively developed.
Another point often brought forth against Qt is that Qt doesn't have a certain feature X, say pluggable styles, and that since one is not allowed to distribute modified copies of Qt we won't get that feature X. The fact is that Troll Tech has put all its resources behind the development of Qt.
Given the fact that Qt is about 80,000 lines of code and the fact that Harmony has already written about 25,000 lines within the last 3 months there is a real chance that a usable Qt clone will be available within a year's time.

 Long QT syndrome
In some people with long QT syndrome, fainting spells are triggered by sudden bursts of adrenaline in the body, such as are experienced during intense exercise or emotional upset.
In inherited long QT syndrome, the heart may be likened to a "ticking time bomb" and it's largely unknown whether the "bomb" is a dud or about ready to detonate with just the right (or wrong) trigger.
Families with inherited long QT syndrome may find it helpful to talk to a cardiologist with expertise in diagnosing and treating long QT syndrome, a genetics counselor, a psychiatrist or psychologist as well as other families with the condition.

 Qt and PyQt   (Site not responding. Last check: 2007-09-10)
Qt and PyQt are quite fast; the design of Qt and PyQt is thoroughly object-oriented; Qt comes with a much larger collection of well-designed widgets than does Tk.
On the downside, Qt has a more restricted license than many toolkits (at least on non-Linux platforms); it is often tricky to get Qt and PyQt installed correctly; as well, Qt is a quite large library.
In particular, it is available under the GPL on UNIX/X11 platforms and the Qt Palmtop Environment environment on the Zaurus, and a free-as-in-free-beer Windows package for an older version of Qt also exists.

 freshmeat.net: Tutorials - Benefits of the Qt Object Model   (Site not responding. Last check: 2007-09-10)
Actually the problem was that Trolltech released a "free" qt under the QPL license, which was more or less compatible with the GPL, except that it didn't guarrantee that the license wouldn't be revoked or changed in the future.
The relicensing of QT under the GPL was a good move, as it allowed a truly free environment o be created, but it preserved the ability of Trolltech to still sell their toolkit to developers who were developing proprietary software.
I imagine that most people here who are debating the merits of QT are professional programmers and would like to use it to accellerate their development process.

In other words, the QT interval refers to the length of time it takes cells in your heart's lower chambers to electrically discharge and then recharge.
Medications capable of prolonging the QT interval and upsetting heart rhythm include certain antibiotics, antidepressants, antihistamines, diuretics, heart medications, cholesterol-lowering drugs, diabetes medications, as well as some antifungal and antipsychotic drugs.
People who develop drug-induced long QT syndrome also may have some subtle genetic defects in their hearts, making them more susceptible to arrhythmias from taking drugs that can cause prolonged QT intervals.

 LinuxPlanet - Reports - Trolltech to Release Qt Under GPL - Decision Alters Linux GUI Landscape
According to Eirik Eng, president of Trolltech, the decision to GPL Qt was a natural one given the evolution of the Linux platform.
"While Qt was without a doubt the best technical choice, some members of the free software community didn't agree with Qt's licensing," said Matthias Ettrich, founder of the KDE project (and a Trolltech employee).
Members of the Linux community who formerly opposed KDE because of the Qt licensing terms hailed the decision to GPL Qt as being healthy for the Linux community.
