I am using an independent version control management program (SmartGit) alongside Qt Creator, and I would prefer not to use Qt Creator for version control management.
It is becoming a nuisance that Qt always prompts me regarding whether I'd like to add new files to Git (when I add new files to the Qt Creator project), and whether I'd like to remove files from Git (when I remove files from the project).
Earlier today, I mistakenly added a file to Git through Qt Creator when adding a new file to the Qt Creator project. A few minutes later, I wished to temporarily remove the file from the project (likely to be re-added later). When I removed the file, Qt Creator dutifully asked me if I'd like to remove the file from version control - giving me a warning that the file might be removed permanently from the file system. Understanding the risk, I nonetheless decided to test the behavior and I said "yes, remove the file from Git as well as removing it from the project". Just as the warning forewarned, the file was removed from the file system and I then had to reconstruct it.
I could simply live with it and occasionally use Qt Creator's version control features in addition to SmartGit's, and/or I could use SmartGit directly to deal with any mistaken occasional uses ogreatf Qt Creator's version control features. However, I'd rather simply disable Qt Creator's version control features entirely, for convenience.
I looked through every Qt Creator option I could find in order to see if it is possible to disable Qt Creator's version control features (even if the project's files are under version control). Unfortunately, I cannot find an option to disable Qt Creator's version control features, anywhere. A careful Google search also revealed nothing.
Is it possible to disable Qt Creator's version control features, even if the project's files are under version control? If so, how is it done?

When I add new files to an existing Qt project the files don't show up in Qt Creator's directory tree until I close and reopen the project.
This behavior only concerns one of the projects I am working on which by now contains more than 800 files (including sources and all resources). Sadly I can not remember when this behavior started to occur.
It is so far not reproducible. If I add files to a fresh project they show up in the tree view right away. Can this be a problem concerning the project settings, or could this be a settings issue with Qt Creator?
I suspected the Mercurial plugin, since I use Mercurial for version control. However deactivating it has brought no improvement.
I should have asked this question before asking this
I am creating a QT app (on MAC) that should use frameworks compiled from qt-everywhere-opensource-src-5.5.1.tgz and not the one that comes with qt-opensource-mac-x64-clang-5.5.0.dmg.
I use QT creator installed by that DMG file and qmake in it somehow links with the frameworks installed by this DMG. (see this for more details)
Whats the legit way of making this QT creator use other framework.
Qt Creator has the concept of build Kits. A kit includes (among other things) a compiler, debugger and Qt version. In the Qt Creator preferences, go to the Build & Run section. Under the Qt Versions tab, ensure that your Qt 5.5.1 built from source is listed there. Then go to the Kits tab and either create a new kit or modify an existing one. Ensure that kit is using your Qt 5.5.1 version.
Once you've got that sorted out, a project can have one or more kits associated with it. From the main window, go to the Projects panel. Near the top of the Build & Run tab of the projects page will be the section where you select the kit(s) for the project. Ensure your project is using the kit you created/modified which uses your Qt 5.5.1. That should be enough to get your project building with your version of Qt instead of the one that comes with Qt Creator. To be absolutely sure, perhaps delete any previous build before you switch kits or even better, create a new build configuration in a new build/output directory for it.
I'm developing a closed source application and to do so in accordance with the LGPL I have to dynamically link Qt's libraries to my application. Does Qt do this by default or do I have to take steps to do so? If that's the case how would I go about doing it?
Qt uses dynamic linking by default.
You'll notice this immediately during deployment to a non-developer machine, because your code will not run without the Qt libraries.
If your concern is the LGPL, just be careful when compiling Qt itself. Most LGPL violations with Qt are not because of static linking (since dynamic is the default), but for compiling Qt with non-default parameters.
LGPL is not just that the library must be provided along your binaries, but also that you specify how your users can build themselves the LGPL part. If you compile Qt yourself and do not use the pre-compiled binaries from the website, you must document that part of your build configuration in your release!
As soon as you get something running on your program, start preparing a release version for a non-developer environment without Qt installed. Your program should fail as soon as you delete the DLLs that you must copy along your program (or whatever format your OS uses).
It does it by default, statically linking seems to be quite involved judging by the many questions on the site regarding it.
Qt was messing up on Windows so I deleted it and re installed it with the qt libraries and Qt Creator. Now, whenever I try to open my old project, I get the error that "Qmake is does not exist or is not executable", and none of the Qt headers can be located.
Assuming you're using a recent version of Qt, such as version 4.7.4, and a recent version of Qt Creator, such as the branch 2.3 .*.
Probably somewhere in this process, Qt Creator or the settings for this specific project lost the reference to Qt install.
We first need to find out if Qt Creator knows where Qt is installed. Go to Tools > Options.... Then click in Qt4. Here will show all installed and detected Qt versions.
As you can see, I have one Qt version installed (4.7.4), which was automatically detected.
If you do not have any installed version, you need to indicate a one manually. Simply click Add and point it to the right qmake.exe. Use the paths of the figure as reference. If you are developing a windows/mingw application, just need to add the qmake.exe associated with mingw (c:\qtsdk\desktop\qt\4.7.4\mingw\bin\qmake.exe on my computer) and remember the Version name, we'll need that in next step.
After that, open the project and click on Projects in the lateral bar. You need to Substitute the Qt version. Click on Manage next to it and select the correct version. This should resolve the problem.
Any trouble just comment. Sorry about the creepy english.
I have multiple installations of Qt4 on my Windows XP SP2 machine and have installed Qt Creator 2.1 today. However, running the project (.pro) files spawns the oldest version of Qt Designer installed (the one installed in 2009 together with the rest of the framework).
Since
I would not like to remove any previous installations of Qt
and for some obscure reason even if I explicitly ask Windows Explorer to always use the version I need it does not
I would like to give up a bit and just sript the needed behaviour in a .bat file like:
e:\path\to\qtcreator.exe %1
This opens Qt Creator, but something seems to prevent it from treating the .pro file properly (in short, the project does not "open" as it should).
Qt documents have a page on the matter at Qt Creator: Using Command Line Options, but it seems to ignore the topic in question.
Since Qt (being as excellent framework as it is) is also known to have its quirks (like that of qmake), I wonder, may be there is an undocumented way to solve my problem?
(Another way to fix the thing would of course be to make the correct version of Qt Designer run, but frankly I'd prefer the "hard-wired" solution since the mechanisms provided by Qt itself are still a bit unreliable.)
The libraries and tools used for a particular project (and a configuration in it) is set in the Projects panel in Qt Creator:
http://doc.qt.io/qtcreator/creator-build-settings.html
Selecting the Qt version to use with a project should force it to run the Designer that's part of the version. If it doesn't, then you should report it as a bug.
