Different versions of Qt and Qt Creator

[gib]

I am using Qt Creator 3.1.0, which is based on Qt 5.2.1 (MSVC 2010, 32 bit), with Qt 4.8.6, which I built with MSVS11, 32 bit.
I can add a QComboBox widget to my ui, but when I try to compile I get this error:

D:\spheroid-abm\build-spheroid_GUI-static\ui_spheroid_GUI.h:2577: error: C2039: 'setCurrentText' : is not a member of 'QComboBox'

Does this mean that I have to revert to a version of Qt Creator built with Qt 4? (I want to stick with Qt 4.8 for now.) If so, how can I obtain Qt Creator based on Qt 4.8? The downloadable versions that I've found are all 3.1.0.

QtCreator can deal with any compiler/Qt combination.

But these combinations, called "kits" need to be configured.

Tools -> Options -> Build & Run.
Configure a compiler, configure a Qt version, combine both in a new Kit, use that kit when configuring the project.
