Flags: object cannot be interpreted as an integer

[sophia73583]

Hi,

I have been trying to set some flags for my widget, but seems to be running into issue on my Mac. I'm not sure if this is a Mac specific issue:

# code to make item in a ListWidget non selectable
list_item.setFlags(list_item.flags() & ~Qt.ItemIsSelectable)

# Error:
TypeError: 'PySide2.QtCore.Qt.ItemFlags' object cannot be interpreted as an integer

I'm getting the same error when setting WindowFlags and WindowTypes. Is this a MacOS specific issue or python specific issue?

Using and instead of & fixed my issue. Might have been issue with a later version of PySide.

Hi,

It has nothing to do with macOS rather Python.

While I can't check right now, one thing you can do in between is the use the setFlag method to disable the specific flag you want to remove.

I see! Although most of the references I found online all use setFlags (e.g. https://forum.qt.io/topic/64392/how-can-i-setflags-as-i-setitem/2).

AttributeError: 'PySide2.QtWidgets.QListWidgetItem' object has no attribute 'setFlag'. Did you mean: 'setFlags'?

If & ~ is not the right way to disable a flag in python, what is the right way?

For setFlag, it's a method of the QFlags class.

It might have fixed the error but I am surprised/you seem lucky it gives you the correct behaviour. In Python & is bit-wise AND, which ought be wanted here, while the and you are now using is logical True/False result.
