It works here with the QT Frequency Sink. You have to double click.
Here's the test flow graph.

I am working on a receiver panadapter application. I would like to use
the QT GUI Sink Clicked freq variable parameter to control the
receiver local oscillator to recenter the spectrum. I tried a simple
test flow graph using GNU Radio version 3.7.13. When I click on the
GUI Sink spectrum, the Signal Source frequency and Label value does
not change. This bug has been reported before. Has this problem been
fixed in later versions of GNU Radio?
Thanks,
