BREAKING BUG - PySide6 issue

[hannesdelbeke]

when running plugget_qt.show()

LogPython: Error: TypeError: 'PySide6.QtWidgets.QWidget.setLayout' called with wrong argument types:
LogPython: Error:   PySide6.QtWidgets.QWidget.setLayout(QVBoxLayout)
LogPython: Error: Supported signatures:
LogPython: Error:   PySide6.QtWidgets.QWidget.setLayout(PySide6.QtWidgets.QLayout)

# after changing the layout code from 
layout=QHLayout()
layout.setlayout(parent)
# to 
layout=QHLayout(parent)

it works now, but a new error.

LogPython: Error:     layout.addWidget(self.package_list)

works in pyside2

[hannesdelbeke]

this code works outside unreal, but crashes in unreal. works in unreal if we swap to pyside2. something with pyside6 is incompatible in unreal

from PySide6 import QtWidgets

app = QtWidgets.QApplication()
window = QtWidgets.QWidget()
layout = QtWidgets.QVBoxLayout()
window.setLayout(layout)
window.show()
app.exec_()

this code throws an error

LogPython: Error: Traceback (most recent call last):

restarting unreal fixed this. i m used to not having to do this in maya and max after installing qt.

[hannesdelbeke]

this is back, sometimes it works on startup, sometimes it doesn't. believe it might be related to when i restart, it asks to recompile the project

[hannesdelbeke]

seems a pyside bug https://forum.qt.io/topic/155934/pyside6-7-is-majorly-broken-typeerrors-everywhere

[hannesdelbeke]

commited a workaround to plugget_qt for now
