I created a single view application with storyboard using xcode 4.5, and looked for NSTable view in objects library, but could not find it. Before I created a stores board I could see this in the objects library but immediately after the creation of a storeyboard I could find only UITableView. My goal is to create a grid kind of interface. Any pointers on this will be helpful.
Thanks

NSTableView is for Mac OS X storyboards. UITableView is for iOS storyboards. You probably created the wrong kind of storyboard.

Given qt3d's structure, is it possible to integrate the oculus sdk with a qt3d application?
I have tried but my two main obstacles are:
I cant use the textures from the texture swap chain created by the oculus sdk as a render target attachment
I am not able to call ovr_SubmitFrame at the end of each frame since qt3d doesnt have a signal that would allow me to do so.
Has anyone successfully gotten the oculus sdk to work with qt3d? If so, how did you overcome these issues?
Are there any plans for allowing the integration of VR SDKs (not just oculus') in qt3d in further releases?
You could probably do it with some sort of custom framegraph that encapsulated the stereo rendering functionality and included a custom component that could take the currently rendered content and submitted it to the SDK prior to the swapbuffer call.
Alternatively you could dive into the code that processes the framegraph itself and see how hard it would be to customize it to work against a VR API. I've done significant work with integrating Qt apps with VR, but not specifically with Qt3D.
The frame graph will indeed provide one part of the solution for the stereoscopic rendering setup. There is already an anaglyphic stereo example showing most of what you need that ships with Qt 3D.
To integrate the swap chain of the occulus SDK will require deeper integration. I do not know the details of the Occulus SDK as yet but we can take a look.
From what I can see you should be able to do something analogous to the Scene3D custom Qt Quick 2 item to be able to render to the textures provided by the Occulus SDK and to tell Qt 3D which OpenGL Context to use. See
http://code.qt.io/cgit/qt/qt3d.git/tree/src/quick3d/imports/scene3d?h=5.7
Nicolas, I also do not appreciate you publicly saying that KDAB are not much help. I only received an email from Karsten on Friday which I responded to despite being on vacation saying that we can help but it will be on a best efforts basis since you are not paying and I have a very full workload preparing Qt 3D for release at the end of the month along with Qt 5.7. Today is a public holiday in the UK, as you are aware, yet you are already saying detrimental things about us.
You were also directed to post to the interest#qt-project.org mailing list on the qt-forums as I do not tend to monitor SO or the qt-forums on a regular basis. You could have also emailed us directly or via the development#qt-interest mailing list.
We would be more than happy to set up a support agreement with you.
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?
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 was excited to find out that Adobe released the data visualization for free so I can use the fancy charts and all with my projects even though I don't have Flex Builder Professional. So I installed the new 3.4 sdk along with the data visualizations. Most all of my projects did fine except for one. This particular project uses localizations. Are there any new compiler arguments that I need to include? I current have -source-path=locale/{locale} -allow-source-path-overlap=true. I get the inconsistent linkage error below:
Inconsistant linkage in /Applications/Adobe Flex Builder 3/sdks/3.4.0/frameworks/locale/en_US/datavisualization_rb.swc$locale/en_US/core.properties - 'en_US$core_properties' is marked as extern, but 'en_USGBC$core_properties' is not.
Any help would be appreciated.
Try use -locale en_US
I am a newbie in flex.
Latest task is to generate a graph or a netwrok based on the data input.
What is the best way to do it. Also when clicked on a node of a network it should show the associated data with that node.
Hope to get some help soon!
Thanks,
Kartik
You need to get a license to flex builder pro to use the Flex Graphing components. You can see what components are available with example code from this link
http://examples.adobe.com/flex3/componentexplorer/explorer.html
Open the data visualization folder to get to the charts.
