[Gambas-user] QT5 Configuration on Ubuntu 16.04

[Gianluigi]

On Ubuntu 16.04 I had understood that QT5 Configuration Tool (qt5ct) was
for QT5 as QT4 Configuration for QT4.
I obtained from PPA as well:
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install qt5ct
As soon as installed, there was to be added to ~/.profile this line:
QT_QPA_PLATFORMTHEME=”qt5ct"
then restart.
Unfortunately it does not work, someone knows more than me?
