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 cannot 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.
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! http://groups.google.de/groups?th=b2a1ba41312c9ae5

TS - It seems that a Qt binding already exists, but it's not yet available... http://groups.google.de/groups?selm=5e97e053.0305200357.2f4ac182%40posting.google.com

http://sourceforge.net/projects/tcl-qt Use [info commands Q*] to list the new ones.
An additional qt binding (relatively recent, November 2005): http://sourceforge.net/projects/qtcl/
Tq [L3 ] 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?
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)
* 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
* 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
