Is there a way to run Qt Creator from command line supplying a .pro file to open (or how do we deal with multiple Qt installations)?

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 ve开发者_开发知识库rsion 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.
