[Interest] Best Practices returning data from a dialog

It depends on functionality you need and type of your dialog (modal/modeless)
In any case I do not think appropriate time is when dialog is closed.

Check QDialog documentation for example at:

In general for modal dialog you might want to update data when
as reaction on 	accepted () signal or when exec returns
with QDialog::Accepted

For modeless dialogs (in general) you might update data as soon it is
changed in the dialog or button Ok/ Apply clicked (again depends on
the design).
Common sense is the best practice.
