Hello, Wanderson,

First, thank you so much for a great starter kit with a really rare dark theme!

You need to pass Ui_MainWindow() instance (in our case it is inside main.py). You can modify it the same way like in ui_main.py except you need to call from passed instance, like self.ui.label_6.setText(QCoreApplication.translate("MainWindow", u"HOME", None))
