As you can see from the video [1] operations paste and drop works fine.
However, with this configuration [2] I can not paste or drop a piece of text to
a specific position of the cursor is the clipboard and mimedata are inserted at
the end of the line! You can also see this problem in the video!
Thanks for your time!!
Anyway, if you can not replicate it, apparently it's just my problem!
I can send you the source code (a simple widget) so that you can replicate
it!

Re: [PyQt] QPoint not automatically cast to QPointF
Hi. Thanks for your reply. What you have to do in SIP, is it of the nature
of a workaround to Python's inability to do the conversion automatically?
Or Python is able to do the conversion automatically and SIP just needs to
present the classes in a proper manner as required by Python?

It requires a change to SIP to handle this automatically which is on the
TODO list but I haven't got round to it yet.
