'close QDialog and back to the first QDialog
I just started learning Python and PyQt5, and I have this problem, I create two QDialog, the first one have a button to open the second, and in the second I have a formular with button "valider", I want when the information are set and the button clicked information goes to database (not the problem) and the QDialog be closed and back to the first one. The two QDialogs are in different files .py .
This is the error I get:
NameError: name 'Dialog2' is not defined
