Hi,
Sorry for my late reply.
After upgrading PyQt to version 5.7, this problem no longer occurs.
However, the look'n'feel becomes strange.
I'm using Ubuntu 16.04 LTS.
In PyQt 5.6, all Qt Widgets have native Ubuntu's look'n'feel.
But after upgrading to version 5.7, their look'n'feel changed.
For example, in PyQt 5.7 the file dialog becomes:
http://i.imgur.com/veYfvjX.png
which is not the native look'n'feel in Ubuntu.
The same problem also occurs on Ubuntu GNOME.
Any ideas?
Thanks for your help.
