Are there any classes within the Qt API that provides some form of interactive guide? An interactive help of sorts. It's become the norm in web UX, but wanted to know if Qt provided anything out of the box for this.
Here's some examples of what I mean.

I recently wrote a Qt based library to manage requests to TheMovieDB.org for a professional desktop application.
Not really experienced with QML and QtQuick, I think about migrating this application to QML which seems to be really adapted for.
I began few tutorials with QML...Amazing.
And now, I wonder if I can integrage my wrapper library into a QML application ?
Basically, let the user capture a movie name into a nice QML interface, froward the input parameters to the c++ wrapper, and retrieve the resulting json results + QPixmap object.
Is it something possible ? I found some piece of codes to access QML components from a Qt c++ application but the inverse yet.
Or maybe am I thinking the things the wrong way ?
Have you ever wrote something similar, I mean regarding the interaction mechanism?
I am planning to link a Qt project against R to provide some statistical funcionality. I thought it might be quite cute to add some generality to the project by having an R console as a Qt widget within the tab to allow me to do analyses that I haven't thought of in the design stage later on. I was wondering whether it is something that might be accomplished fairly easily?
In particular I'm stuck on how I would access the RTerm from QT? Has anyone else attempted something similar or can give some hints on where to start?
One of the examples for RInside does something pretty close---in around 200 lines most of which deal with the other GUI aspects, it wraps R functionality inside a Qt application.
The example implements a GUI density slider, and the edit box allows you to write an almost arbitrary R expression, or rather the parts that are then passed into an evaluation to generate random number: rnorm(50), or for a mixture c(rnorm(50), rt(50)) etc. You could possibly build on top of that.
See this blog post for more.
Check out Carson Farmer's work on manageR:
http://www.ftools.ca/manageR/
this is a plugin for Quantum GIS (mapping package) that interfaces it to R, giving you exactly what you want - an R console wrapped in a Qt4 body - as well as data transfer between Qgis and R. It handles plots as well.
I've tried to encourage Carson to produce a standalone R Gui project from this code, but he's a busy guy. Aren't we all?
RStudio is largely written using QT, you should be able to have a look at their code and build something similar into your Qt based application:

I'm about to make a program (qt/gtk) where I need to display some kind of UML diagrams (like in BlueJ),
I wanted to ask you if there is such a component in GTK
It must work with new version of Gtk - gi.repository
The name of library is enough for me, I'll read docs, but if somebody post here some simple demo, it'll be appreciated.
Thank you
Dia (Old homepage) is a GTK based UML drawing tool. It is a very good tool with a lot of options. It is available on a number distros from their repositories. It has both application & library (libdia) components. There are python bindings available as well. If you have not checked it out, you should.
Hope this helps!
I found gaphas
You should checkout GooCanvas, I think is the more complete library for that kind of work.
I use python and pygtk, and use matplotlib to draw graphs in the GUI.
See a sample here : http://www.serpia.org/blog/2007/nov/03/matplotlib-and-pygtk-app/
Once I've seen a nice tool called .NET Reflector. It can show the entire object hierarchy of .Net binaries/apps (sorry if the term is wrong).
Is there something like this for Qt? As Qt has very good QMetaObject abilities, it should be possible to traverse object-trees, call methods(slots), change properties, etc.
I am currently re-factoring a Qt project. The naming of variables is very domain specific and I am not the expert in this domain. So, it is difficult for me to map a widget-variable to the widget on the screen. Such tool would be a great help for me to understand the code.
Thank you very much in advance!
For simple uses you might want to take a look at QObject::dumpObjectTree()
If you need something more advanced there's kspy
kspy: examines the internal state of a
Qt/KDE app KSpy is a tiny library
which can be used to graphically
display the QObjects in use by a
Qt/KDE app. In addition to the object
tree, you can also view the
properties, signals and slots of any
QObject. Basically it provides much
the same info as
QObject::dumpObjectTree() and
QObject::dumpObjectInfo(), but in a
much more convenient form. KSpy has
minimal overhead for the application,
because the kspy library is loaded
dynamically using KLibLoader. See /usr
/share/doc/kspy/README for usage
instructions. This package is part of
the KDE Software Development Kit.
It depends on KDE's klibloader so if you are not under KDE you have to modify it but it should be rather easy. Sources are here.
There's QSpy project. It inspects all QWidgets of running application. I'm not sure how well it works, because I couldn't use it on Mac OS X. Maybe on Windows it works better. https://github.com/sashao/martlet

I'm new to Flex but need to generate some visualizations of some time-based data. Any recommendations for tools that would work well in Flex?
Be sure to keep an eye on a new project called Axiis that was recently announced by Tom Gonzalez, a prominent Flex developer. It's a data visualization framework that should make custom charting very interesting.
Flex Builder Pro gives you access to the graph visualization library in mx.charts.
If you want an open source solution, you can try Flare.
If you're willing to pay for it (I think it's in the USD $250 range), Flex Builder Pro is definitely the way to go. The graphing and charting power in the libraries is impressive. It's quite simple to generate nice looking, complex graphs with not much coding.
Something other that the builtin mx.charts?
I'm using the standard Flex Charting - which is extremely configurable - we've been able to make it look pretty much how we want it to...
However, also take a look at iLog Elixir - they provide some superb additional charts that you might find useful - particularly the 3D charts. The Radar chart can be very effective in some situations but you really need the RIGHT place to use such a thing. Also they have a good heatmap and pivot charts.
Regards,
Jamie.
Some very interesting charts, and they have free-with-logo and pay-and-have-the-source versions, is amCharts. They can be used directly in a web page, feeding settings by XML and data by CSV (as services, by javascript or whatever) and also inside Flex projects.
