And part of that solution is to have a properly configured Visual Studio
C++ environment, which I've addressed as well as the "Upgrade" portion.
I'm not sure the problem here.

No. There are many solutions to a missing C++ compiler.  My comment (not a
solution!) is specific to Visual Studio 2015's C++ compiler.  Its
contextually relevant to both the title as well as the description of the
OP, especially considering it's where people land when they're setting
things up.  Perhaps the best solution is to provide this information on the
Qt installation instructions page before people download the IDE, but I'm
not familiar enough with Visual Studio to know what the defaults are, so
I've left a breadcrumb for people in need.

The solution for the original question is to upgrade Qt or to build from 
sources.

Your solution is to the problem of "I don't have a C++ compiler".

I'm sorry if there was any confusion.   I was  intentionally linking the

That SO question was about support for MSVC2015 with Qt 5.5, which did not 
come with a pre-built version for that compiler.

Qt 5.6.0 does.

[Interest] OSX 10.11.4 network socket issue

[Alexander Carôt]

Hi all,

I have a strange issue with the latest OSX 10.11.4:

My app deals with low-delay audio interaction has been actively used for many 
years (http://www.soundjack.eu):

It grabs every soundcard buffer and sends it via UDP to a destination, where it 
is bufferend for a desired amount of time and then played back on the 
receiver's end.

So the (simplified) sequence looks like this:

SENDER AUDIO CALLBACK
SENDER THREAD
RECEIVER SLOT
BUFFER THREAD

If the sender and receiver system works fine this sequence is always the same, 
however, with the latest OSX 10.11.4 the receiver slot does not react 
immediately anymore leading to sequences like this:

SENDER AUDIO CALLBACK
SENDER THREAD
SENDER AUDIO CALLBACK
SENDER THREAD
SENDER AUDIO CALLBACK
SENDER THREAD
SENDER AUDIO CALLBACK
SENDER THREAD 
RECEIVER SLOT
BUFFER THREAD
RECEIVER SLOT
BUFFER THREAD
RECEIVER SLOT
BUFFER THREAD
RECEIVER SLOT
BUFFER THREAD

This behaviour completely messes up my system but I currently have no idea how 
to approach this issue.

Obviously the problem is not related to Qt because it does not matter if I am 
using the old Qt 4.8.x or the latest. Neither it is related to Windows or Linux 
- it only happens with the latest OSX.

Any help appreciated.

Thanks in advance

Alex

[Interest] Fix QML Camera's frame rate and change it resolution

[Suornoms Siademont]

Hi!
Can it possible to fix frame rate and change resolution of Camera? Tried to use

viewfinder.maximumFrameRate: 10
viewfinder.minimumFrameRate: 10

and

viewfinder.resolution: Qt.size(640, 480)

- no effect.

How can I access the QML Camera from Android's Java side (I mean in
QtActivity class)?
What does Qt use for creating Camera on Android devices?

Re: [Interest] widget rendering (alignment, sizing) issues on OS X

[René J . V . Bertin]

René J.V. Bertin wrote:

I think I posted the question below to the wrong list.

Has anyone ever noticed widgets not being aligned correctly because of sizing 
issues on OS X, outside of KDE applications, as shown in the link below?
https://bugs.kde.org/show_bug.cgi?id=363423

I've dug around some more on this and had some feedback which led me to 
understand that this happens when widgets are used that somehow do not use 
QMacStyle but QStyle instead.

The fixes I found are extremely simple, requiring only the 
Qt::WA_LayoutUsesWidgetRect attribute to be set on the widget in question:

https://git.reviewboard.kde.org/r/128002
https://git.reviewboard.kde.org/r/128004
https://git.reviewboard.kde.org/r/128005

The issue also occurs with comboboxes but I haven't yet identified where I 
could 
try the same fix.

The question that has come up is whether this attribute shouldn't simply always 
be set in QPushButtons, as there appears to be no effect of setting the 
attribute on Linux (or when using other widget styles on OS X).

Thoughts on that?

Re: [Interest] Qt 5.6.0, QtCreator 3.6.0 and MSVC2015 - Compiler Issue

Not sure if this is relevant, but I had a similar issue and it was because
I had taken the default options with MSVS 2015 and never explicitly
installed a C++ compiler.

What worked for me was opening Visual Studio, creating a C++ project and
Visual Studio prompted to install MSVC 2015. Once that was done, relaunched
QtCreator and it was fine.

Re: [Interest] [QT3D] 3d Object and texture loads

[Xavier Bigand]

I don't think that it exist a 3D format that is made to have a fast
loading, obj, collada are text based format and even FBX that is a binary
format seems to give fat and complexe hierarchy files.

If you really need performances the best is to do a custom file format that
feet your needs. For exemple you can use protocol buffer and put only
vertex data you need directly in the correct format.
By archiving geometry data in a format that doesn't require any conversion
for the graphical API or the GPU will give you the fastest loading times.
For textures it is recommended to use compressed textures (pvrtc, dxtc,
etc,...), but because the compression is fixed it is interesting to add a
fast compression step before with a lossless algorithm (lzham, bzip,...) to
reduce the file size to something close to png or jpg results.

[Interest] Qt 5.6.0, QtCreator 3.6.0 and MSVC2015 - Compiler Issue

[Cjb_SW Freescale]

Dear All,
I want to use Qt 5.6 on Windows (my OS is Win10 64bit) with MSVC2015.
I have downloaded Qt 5.6.0 x86_MSVC2015 prebuilt binaries, together with
QtCreator 3.6

I also have MSVC2015 professional, which was already installed on my
machine.
I can run QtCreator, but I can't configure a compiler for that version of
Qt, since I do not have MSVC2015 in the auto-detected compilers tab.

And of course I cannot work..

Any suggestion?

[Interest] Does Qt support Vybrid's GPU?

[Timur Kristóf]

Hi Everyone,

I've taken a look at the list of supported reference devices here:
http://doc.qt.io/QtForDeviceCreation/qtee-supported-platforms.html

Some of the devices in Group 1 are the Toradex Colibri boards which are
based on NXP's Vybrid SoC. However, these are listed under "Devices
without GPU", whereas the Vybrid chip (according to its datasheet) does
have a GPU. (It says it's an OpenVG GPU.)

Is this an oversight in the Qt docs or does this mean that Qt doesn't
(yet?) support the GPU in Vybrid?Best regards,
Timur

Just use QScroller for this.
E.g.
in the constructor of your QListView:

QScroller::grabGesture(this, QScroller::TouchGesture);
