global local vars issue

[hannesdelbeke]

when we use exec to run python code from a text file, the locals and globals inside the exec are lost. so w = QWidget() will instantly be garbage collected.

How can we keep the reference? tried but no luck so far

exec(self._command, globals(), globals())

it seems to pass the var correctly but widget still garbage collected. testing with import buttonizer.main; global w; w = buttonizer.main.show()

see https://www.programiz.com/python-programming/methods/built-in/exec

• the exec globals and locals are supposed to be used by exec
• when printing afterwards, they appear modified
• https://docs.python.org/3/library/functions.html#locals says to not edit the locals
• when saving the locals to the operator, the widget still appears to be garbage collected

think this was a bqt bug masquerading as a unimenu bug, closing
