Run examples/printerdemo/python/main.py failed.

I followed api/python guide to run example of python, but get error when I execute pipenv run python main.py

Traceback (most recent call last):
  File "E:\self\gitProjects\slint\examples\printerdemo\python\main.py", line 61, in <module>
    main_window = MainWindow()
  File "E:\self\gitProjects\slint\examples\printerdemo\python\main.py", line 22, in __init__
    self.printer_queue = ListModel(self.PrinterQueue.printer_queue)
AttributeError: 'SlintGlobalClassWrapper' object has no attribute 'printer_queue'

It may be due to the loss of the appwindow.slint file, as indicated in the content under the title Quick Start.

I'm sorry I should read more guide.
