Hey guys,

I am writing a rqt plugin in python and want to restore my settings (which check box was checked for example) through instance settings like a lot of people did in their plugins but it does not work. When I try to print the value I always get 'None'.

In "save_settings" I am writing:

"instancesettings.setvalue('checkbox', self.ui.checkbox.isChecked())"

and in "restore settings":

"self.ui.checkbox.setChecked(instancesettings.value('check_box', True) in [True, 'true'])"

The problem is that my value never gets saved. It always stays True for example.

I don't really understand the value function so I looked up the code in "qtguiplugin" and afterwards the documentation of the QSettings value function and I still don't know why it does not work.

Maybe someone can help me with this, would be really appreciated!

Thank you in advance!

Best regards
