Hi,
In order to fix a breakage when running Android apps after a Qt upgrade, I have recently cleared out Qt caches in AppData/Local and AppData/Roaming, as well as removing the original build directories.

This fixed the problem but I am left with Qt default formatting options for the C++ code, which I really can't use. I want to customise code indentation, specifically to indent all blocks with 4 spaces. So:

namespace foo
{
    namespace bar
    {
        class Baz
        {
        };
    }
}

instead of

namespace foo
{
namespace bar
{
class Baz
{
};
}
}

and so on, with TAB meaning "indent leading whitespace only" and without ther aggressive auto-formatting enabled.
There are several more options I would like to set, but these are the main ones.

I just can't find any way to set Edit->Preferences->C++->Code Style to do this.

I have struggled with this in the past and somehow managed to find an acceptable solution, but one evades me now.
Any help with this would be greatly appreciated.
