Firstly, make sure you are setting an organization and an application name,
so that you don't collide with another Qt application:
http://doc.qt.io/archives/qt-4.8/qsettings.html#QSettings
The reason you aren't seeing your saved text being loaded to your UI is
because you forgot to actually setText the value:
def load(self):
settings = self.settings
print '>>> ', settings.value('lineEdit2')
self.lineEdit2.setText(settings.value('lineEdit2', ''))
Note the second arguments to value() is the default to use if the setting
wasn't not previously set.
