# Uncrustify4Qt: Where do the options work?

## Indenting

    // indent_with_tabs     = 0 spaces only
    // indent_cmt_with_tabs = false
    int foo::bar()
    {
        int a;
    ^^^^
        double a_very_long_variable = test (foobar1,
            foobar5);
        ^^^^
    }
    class Test
    {
     private:
    ^
       int a;
