Yes, I believe so, too. LCL-GTK2 is full of historical remains. Many
of them come from GTK1 times, the sources were just copied. This piece
of code however was not from there.
According to documentation the API has not changed. Why should the
code be different?

No need. I changed it in r53590. Please test.
If somebody finds an old GTK version where it does NOT work then we
will scratch our heads more, but I doubt it.
