Ah yes, of course. Thanks.

I think I was confused because Qt Creator made parent italic when I
wrote it like that, as if it was defined, and I got no errors when
running. I couldn't get that behavior in a simple testcase though, so
not sure why it thought parent was defined there (following the symbol
with F2 did nothing).
