[Interest] QWidget or QDialog as a singleton

[Jérôme Godbout]

my 2 cents, what I do is I make a basic QObject singleton, which provide
signal, anything can hook to the signal and everybody can easily fire the
signal.

QObjectSingleton::showHelpDialog()  could be send from anywhere by any code
and I can then make my Widget change it's visibility based on this signal
connection. This avoid the need to have the widget into a singleton for my
use cases. Not sure this is doable for your use case but might help to have
a cleaner design.
