I'm using the following compilers:
MinGW 4.9.2 32Bit
Microsoft Visual C++ Compiler 12.0 (x86)
with the following debuggers, respectively:
GNU gdb 7.8 for MinGW 4.9.2 32Bit
CDB (\Windows Kits\8.1\Debuggers\x86\cdb.exe)
with Qt Creator 3.5.0 and Qt 5.4.2.
What I would like to see is the pretty printed ("high level") interpretation of a QHash within the debugger watch view. See e.g. this post: https://blog.qt.io/blog/2009/06/22/peek-and-poke/
The pretty printing works with gdb + MinGW but not with CDB + MSVC2012. In the latter, I can only see the 'low level' interpretation.
What do I have do to get this work with CDB + MSVC2012 too?
You will need to add a correct debugging addin dll into the visual studio installation directory C:\Program Files\Microsoft Visual Studio ${num}\Common7\IDE or preferably the add-in directory ( default is %USERPROFILE%\Documents\Visual Studio ${num}\Addins).
Qt already provide a complete set of tools for MSVC integration which can be built from one of the qt git vstool project.
There is a wiki which provide a step by step guide to make it work. Basically :
get the project from repository
create the solution files
build the correct solution, as there is one for each pair Qt4\Qt5 x VsVersion
Copy the target dll to the addin directory.

I cant use std::wstring_convert in Qt 5.1, because it said me that <codecvt> : No such file directory. What can I do? I don't know... this code is working at the MSVC 2013.
QtCreator is just a front-end that allows you to edit your source files, it does not contain a compiler. On Windows you need either MinGW or Visual Studio to compile code.
If you want to use Qt 5.1 with Visual Studio 2013, you would have to compile Qt yourself. Digia provides builds for Visual Studio 2010 and 2012. You can find the latest version of Qt here or an old release here.
My advice would be to install Visual Studio 2012 and download a VS2012 build of Qt. Then go to Tools > Options > Build & Run > Kits, click the Add button on the right (or modify the existing one as it probably won't work anyway). Set the compiler to "Microsoft Visual C++ compiler 11.0 (amd64)" if you downloaded the 64 bit version of Qt or "(x86)" if you downloaded the 32 bit version.
Then set the debugger to cdb.exe and the Qt version to the one you just downloaded (if you don't see it, go to the Qt Versions tab at the top, add it, click Apply and the go back to Kits and it should be there). Click ok and your kit should be ready! Make sure that you don't have a warning signal that would point out a potential mistake.
Now open your project and go to the Projects tab (Ctrl + 5) and make sure your project is using the correct Kit.
You should now be all set up properly.
Additionally, if you don't want to install Visual Studio 2012 and want (or have to) work with VS 2013, you can use the Qt 5.3 BETA builds located here. Please note that these builds are in beta and shouldn't be used in production code, if you want to use VS2013 with Qt in production code I would recommend to build Qt 5.2.1 with VS2013, it's not that hard but it can take a while.
You are missing this in your project file:
CONFIG += c++11
You need to make sure that your GCC version (brought to you by mingw) supports that feature though. It is possible that you are using an old version where it was not supported.
I was seted up a compiler to Microsoft Visual C++ x86 Compiler, but now i have this error:
The compiler "Microsoft Visual C++ x86 Compiler" cannot produce code for the Qt version.
Warning: No debugger set up
I guess that i need to set debugger, but i don't know which path to put Debugger tab.
I have installed Visual Studio 2012.
For binary version of SDK, you need MSVS2010, Express version should be ok. SP1 must be installed on top of these too.
For debugging you also need to install Windws SDK 7.1 and SP1 update for it.

If you want to use MSVS2012, I think you still have to compile yourself. Instructions:

I struggled finding a how-to which provides a stable solution for using Qt with Visual Studio 2010, so after collecting all the bits of information and some trial and error, I would like to write my solution into a guide.
The problem, or why is it not possible to use prebuilt binaries?
It seems that using binaries built for Visual Studio 2008 might work in some special cases, but I found them not to work. In my case they compiled OK, but they produce runtime errors, like this:
or when started from Visual Studio 2010:
Update: I found a blog post analysing why does it work for some people, while it does not for others. In one word, it depends on whether you have Visual Studio 2008 installed on the same machine, or not.
http://blog.paulnettleship.com/2010/11/11/troubleshooting-visual-studio-2010-and-qt-4-7-integration/
The most important thing (that I stupidly didn’t realize) was the fact that you CANNOT use the Visual Studio 2008 compiled libraries and dll’s (available on the Qt webpage) if you don’t have Visual Studio 2008 installed. The reason is because the Qt SDK you download is a debug build which is dependant on the VC9.0 DebugCRT, meaning it needs the Visual C++ 2008 Debug Runtime installed, which is NOT available as a redistributable installer. The only way to install the DebugCRT is to install the entirety of Visual Studio 2008.
First of all, it’s very important to understand that for using Qt with Visual Studio 2010, it's not possible to use the pre-built binaries which were made for Visual Studio 2008, but you have to compile it from source.
Downloading Qt
On https://www.qt.io/download/
Update 2017: the latest Qt 4.x branch (Qt 4.8.6) has 2 pre-built packages, which are now in the archive section:
http://download.qt.io/archive/qt/4.8/4.8.6/qt-opensource-windows-x86-vs2010-4.8.6.exe
http://download.qt.io/archive/qt/4.8/4.8.6/qt-opensource-windows-x86-vs2008-4.8.6.exe
You should not download Qt by clicking "Qt libraries 4.8.6 for Windows (Visual Studio 2008, 218 MB)", but by clicking on the "zip" link above it.
On that link, you get a big zip file like "qt-everywhere-opensource-src-4.8.6.zip". Unzip this into a folder and make its path something nice and small, for example "E:\Qt"
Visual Studio Command Prompt
Now that we have the sources, we need to build the binaries. To do it, open the Microsoft Visual Studio 2010\Visual Studio Tools\Visual Studio Command Prompt (2010) link from your start menu, or even pin it to the taskbar (a good idea). This is a special command prompt which has all the variables set for building with Visual Studio 2010 tools.
Once within the command prompt, navigate to your extracted Qt folder using old-school DOS way, which means you have to change drive letter by E:, enter directories by cd Qt and list dir contents by dir. You can use the tab key for helping you with the directory names. When you have arrived at the correct directory, a dir command should return something like this.
Building Qt
Now it’s time for configure and build. For configuring a minimalist Qt, I'm using the following flags with configure.exe. Just copy and paste it into the command line. Look in the Qt reference manual for what flag to use or not to use.
configure.exe -release -no-webkit -no-phonon -no-phonon-backend -no-script -no-scripttools -no-qt3support -no-multimedia -no-ltcg
Once configure.exe has finished (it was 10 minutes for me), you'll need to start the build process. It will take about 20-30 minutes with the above flags. To start it, just type:
nmake
Setting environment variables
Basically, we are done. All you need to do is to set your environment variables (QTDIR and PATH), which tell programs where to find Qt. If you are on Windows 7, you can use the following command to set QTDIR to your installation dir.
setx QTDIR e:\Qt
For setting the PATH, I strongly recommend using Path Editor. Within Path Editor
add the directory of Qt\bin to your PATH
(it doesn't matter if it's in system path or user path)
If you prefer to use Control Panel\System\Environment Variables, then you can set these there, too.
Qt Visual Studio Add-in
Here you go, after a logoff-logon or a restart, all the Qt demo applications should start correctly (I recommend have a look at bin\qtdemo.exe). Now you can download and install the Visual Studio Add-in (qt-vs-addin-1.1.9.exe) from the Qt download page, it will work perfectly.
Appendix A: Official Instructions:
There is a page at the official wiki at the Qt website called Qt 4.8 Installing Qt for Windows, but I found it lacking important information.

I'm confused about getting Qt working with Visual Studio Express. Most of the searches online have turned up instructions for compiling Qt using instructions such as:
Install MSVC2005 or MSVC2008
Install the most recent Platform SDK (# MSDN: "Platform SDK for Windows
Server 2003 R2")
From the Platform SDK, you'll need to install at least the base +
internet options
Then, download and extract a recent snapshot or the preview release to
D:\Qt\4.x.x
Open up a console with the MSVC settings loaded (see MSVC Tools-menu)
and go to your Qt directory
Type "configure -platform win32-msvc2005" without the quotation
marks
That will build you the project files you'll need
After that, it's as simple as running "nmake" and drinking a lot of
coffee
Then, add D:\Qt\4.x.x\bin and
D:\Qt\4.x.x\lib to your path
environment variable, and you'll be
able to use this version of Qt from
everywhere on your system. The latter
could be added to the library section
in the options from MSVC as well.
(from http://www.qtcentre.org/threads/11710-Visual-Studio-2005-Express)
However, when I go to the download page of Qt (http://qt.nokia.com/downloads), there is a download for Visual Studio labeled:
"Qt libraries 4.7.1 for Windows (VS 2008, 228 MB)"
I'm confused, do I actually still need to build it? Or is it already built?
Using the downloadable exe from qt (http://get.qt.nokia.com/qt/source/qt-win-opensource-4.7.1-vs2008.exe) does not seem to work with Visual Studio 2010. I tried building a simple hello world program from the command line which would not run. I'll repeat my comment from a previous answer.
I tried the hello world example from
doc.qt.nokia.com/4.7/gettingstartedqt.html.
I was able to build the project and an
exe is generated. However, the exe
fails to run and generates a system
error dialog box about "side-by-side
configuration is incorrect...". I ran
SxsTrace and it says:
...

To me, it looks like its trying to use
VS2008 (which I don't have). It makes
sense I guess since the download is
for VS2008.
I was in the process of compiling qt 4.7.1 using the instructions in my question (using win32-msvc2010 as my platform target however) as I asked this SO question and the compilation finished. I rebuilt the hello world project and the exe runs. So it seems like the answer is in order to use with Visual Studio Express 2010 you currently do need to compile (at least until Qt releases a VS2010 download option). However, I believe if you are using VS2008 then you will not need to compile.
The Qt binaries provided by Nokia for Windows target either MinGW or Visual Studio 2008, both for compiling 32bit executables. If you need Qt binaries for VS 2005 (32bit), you may find them in their archives.
For everything else, you need to compile Qt yourself. Especially for:
Visual Studio 2008 64 bit
Visual Studio 2008 Express Edition 64 bit: You need the Windows SDK 7.0 which provides the 64 bit compilers and compile Qt with those.
Visual Studio 2010 32 bit and 64 bit
In general, you cannot link libraries compiled with different compilers, i.e. use the Qt binaries built with VC 9.0 (VS 2008) 32 bit and link them to an executable built with VC 10.0 (VS 2010) 32 bit.
Just a small update on this.
Downloading the QTSDK (and using cmake instead of qmake everything looks like working quite well. Except for the fact that the installer of QTSDK didn't update the path for qmake.exe and you've to do by hand.
Tested with QtSDK 4.8 and visual studio express 2010
http://qt.nokia.com/downloads has a link called qt-vs-addin-1.1.7.exe (57 MB)
You'll probably need that one as well . .
I don't think you need to compile the libraries since there is a download for them now . .
So get the 228 MB of libs and 57 MB plugin and you should be set.
DISCLAIMER: I don't use MSVC (yet?) so please let me know if it works.
On my computer (Win7 32, VS2010 Ultimate) I would like to use Qt Creator and Qt Visual Studio add in, both LGPL versions.
There are minGW and VS2008 versions of Qt frameworks on the Nokia websites, I did not find VS 2010 version.
So I have installed Qt 2010.05 SDK and in the VS 2010 Command prompt the following steps have been performed:
configure -static
nmake sub-src
I checked Qt Creator and it successfully runs. After the translation has been finished I installed VS 2010 add I tried to add new Qt version int the path
C:\Qt\2010.05\qt
But the following error message has been appeared:
Qt in the given path was built using minGW
It do not understand why because the translation has been performed for the VS2010.
Where is the error? How to install it correctly?
I found out from a German Qt forum that, VS add-in looks for libqtmain.a and libqtmaind.a files to determine if it is built with MinGW. Guess what? Qt ships with those files.
Delete them, and you will be fine.
FWIW, The Vs2008 version works fine with VS2010. I didn't need to build it or anything. You can install that and then just run the latest version of the VS plug-in installer and you should see the Qt menu options in VS2010.
AFAIR your command line is incomplete: I remember one had to specify the build platform. It could be that it's using mingw to build Qt since you didn't specify the VS version in the parameters. The following post might be of interest to you: Building Qt 4.5 with Visual C++ 2010
