"""
PYSIDE-68: Test that signals have a `__get__` function after all.
We supply a `tp_descr_get` slot for the signal type.
That creates the `__get__` method via `PyType_Ready`.
The original test script was converted to a unittest.
See https://bugreports.qt.io/browse/PYSIDE-68 .
Created: 16 May '12 21:25
Updated: 17 Sep '20 17:02
This fix was over 8 years late. :)
