Hi,
Is there any site that gather all the documentation about PyQt?
The docs of the Riverbank site is poor, and I have found separate

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
