If furas's translation of the error

Generated code should not be edited manualy because generator may not recognize code and you will not able edit it graphically again.

is correct, you are getting that error because you are trying to edit code generated from a graphical UI designer.

When you use a graphic designer it has to generate code before the UI can be run. If you alter this generated code, it might work on this run, but the graphical design tool won't be able to reinterpret it and will either refuse to allow you to edit the UI file again, or even worse, completely override any changes you made when re-generating the UI code.

Instead consider importing the generated UI code, and making changes or overrides to subclasses of your UI widgets there, instead of in the generated code.
