I'm encountering an issue trying to use true_property and/or snake_case in PySide6. Without either, I can construct widgets using a form like this:
text = QtWidgets.QLabel('Example', margin=10)
where I specify Qt properties as keyword arguments when creating the widget. This does the same thing as:
text = QtWidgets.QLabel('Example', margin=10)
text.setMargin(10)
# Or with snake_case:
text.set_margin(10)
# Or with true_property:
text.margin = 10
However, importing snake_case and/or true_property breaks this "shortcut" constructor. I get the following results:
from PySide6 import QtWidgets
from __feature__ import snake_case
app = QtWidgets.QApplication()
text = QtWidgets.QLabel('Example', margin=10)
# AttributeError: PySide6.QtWidgets.QLabel.__init__(): 'margin' is not a Qt property or a signal
from PySide6 import QtWidgets
from __feature__ import true_property
# Same results from either of these:
# from __feature__ import snake_case, true_property
# from __feature__ import true_property, snake_case
app = QtWidgets.QApplication()
text = QtWidgets.QLabel('Example', margin=10)
# Segmentation fault: 11
Is this a bug, or is there something I'm missing here?
Do I really have to choose between these ergonomic Pythonifications and convenient constructors, or is there a way to get them to work together?
What's causing this behavior?
This was indeed a bug in PySide, which I reported here: PYSIDE-1705.
It has now been fixed as of PySide 6.2.4.
