What is Qt? I think it is a [GUI] library - anyone have more info? What makes it a good match for [Tcl] - or at least, of interest (other than academic)?
Latest versions of [Tile] provides a Qt-based [theme]
[Ralf Fassel] - The homepage of Qt is at http://www.trolltech.com
[TS] - An Intro to Qt 3.0 from Cameron Laird
http://linux.oreillynet.com/pub/a/linux/2001/11/16/Qt.html
With Qt 4, the story changes again; Qt 4 distinguishes both GUI
and "console" functionality, so that, in fact, Qt 4 now makes a
nice convenience library for [C++] programmers writing command-line
applications. [[provide hyperlinks at some point]]
[LV] Hey, if you see a reference to Qt 3.3.8 being released on the trolltech web site,
don't be confused like some of us :-( ... that's the last maintenance release on
a product line that apparently is going away this year. The latest version of Qt appears to be
in the 4.1.x range...
[NEM] - Qt is the library used by [KDE] applications isn't it?
[CL] answers: yes and no. KDE itself is constructed with Qt;
that's true. It's possible to launch an application made with
any X toolkit from KDE, though, so what people ''think'' are
"KDE applications" might only be X applications.
[George Petasis] observes that "Under Qt, the programmer can
control only a few aspects of how the widget looks. The vast majority
of the appearance of the widget is determined by the theme."
Also surprising, from a [Tk] programmer's perspective, is that an
image and a label can''not'' simultaneously decorate a button.
[JH] notes that George is incorrect above. That is a feature of Tk 8.4,
added in May, 2000. People need to really keep up with Tk advances, as
it is moving forward just like all the rest.
CJL - I think 'JH' has misinterpreted George's statement. He (George) is saying that a Tk programmer (who is used to being able to mix labels and images) would be surprised that it can't (or couldn't) be done in Qt.
George has prototyped a [TkQt] at
[ftp://www.iit.demokritos.gr/pub/skel/petasis/tcl/TkQt.tar.gz].
An alternate URL for the same file is
[http://www.iit.demokritos.gr/~petasis/Tcl/TkQt.tar.gz].
Also, [Ktk] worked in a similar direction [[true?]].

Despite explicit discouragement from [jcw], Bill Saunder
remarkably used [Critcl] to script a successful model Qt
application with a functional button. That's [pure-Tcl]
(once one assumes Critcl). Impressive!

[TS] - It seems that a Qt binding already exists, but it's not yet available...

Use [[info commands Q*]] to list the new ones.

Tq[https://www.froglogic.com/productsq/]
is a remarkable-looking commercial product
which bridges the Qt and Tk worlds
in at least a couple of distinct ways.

[Houssem BDIOUI] - I made a Qt widget (QTextEdit-based) that emulates a Tcl console => QTclConsole
Any one interested can email at : houssem dot bdioui at gmail dot com
It has many features : basically the ones of QTextEdit + redirection of stdout/stderr +
colorized result (red, blue) + customization of the prompt + support of any Tcl command
(custom ones defined through Tcl_Interp as well) + history + ...
I'm also thinking of providing a whole QTcl package.
Come on! Noone interested?
The whole project is now under:
http://sourceforge.net/projects/qconsole
In fact, the console is now reeingeneered to support any scripted language (by inheritance).
Tcl is just a specialization.

[LV] It sounds like it would be useful to have available. However, I'm using a GNOME desktop, and am not in a situation where experimenting with Qt is possible. If my situation changes so that I have more disgression, then I'd
be interested in exploring the option.

[CAU] I own a [Zaurus] SL-5500, have done for a while. The Z runs a version of [Qt] under which all applications run. It really would be a boon to write apps with a GUI in Tcl. As it is, Tk is not supported on the Z and I haven't come across a way of using Qt direct from Tcl. Why has this been possible with Python but not with Tcl?
Anyone fancy the challenge?

[Houssem BDIOUI] - A new QConsole version (v1.1) has been released under
http://sourceforge.net/projects/qconsole
It has the following Changes:
- commandsManager class:
* The getInstance() method can take an already created Tcl_Interp parameter
* removed the registerCommand() method
* New unregisterFunction()
* New set of registerVariable() methods to register C++ vars as Tcl ones
* Added support for "help messages" for functions and methods (accessible
through the new 'help' command)
- QConsole:
* Fixed a bug previously allowing inserting text outside of the
edition zone: Bug that can happen when holding the mouse button
pressed outside the edition zone and typing something
* Possibility to select words outside of the edition zone using double clicks
* Overridden paste() removed : handled by the previous bug fix
* Disabled the popup menu
* New public execCommand(QString) method that executes a Tcl command
and dislpays back its result in the console
* New saveScript() method that saves succeeded commands to a file
* New completeCommand() method that gives suggestions to complete the current command
- QtclConsole:
* Redesigned into a singleton pattern
* Implemented completeCommand() based on [ info commands ]
* New Tcl saveScript command
- New TclCallBack class that allows registring/unregistring C++ methods as Tcl Callbacks:
* Used for SetPrompt() and ShowHistory() in QtclConsole
