Exception is thrown from __init__ of WindowsFramelessWindowsBase if multiple inheritance is used in a sub-class about pyqt-frameless-window HOT 3 CLOSED

After looking into it a bit more, it seems that this problem has its origin in a change in PySide 6.5 where correct multiple inheritance handling for _init_ methods was introduced. Since you changed the order of base classes of WindowsFramelessMainWindow and WindowsFramelessDialog the code now fails.

I don't know what the correct fix is but maybe the base class order has to be reverted?

亲 class麻烦初始化一下

class Foo:
    def __init__(self,*args,**kwargs):
        pass

不想初始化的化改下继承顺序，这个对不同版本python表现不一样，不推荐
class MainWindow(Foo,FramelessMainWindow):

from pyqt-frameless-window.

Okay, so just switching the order of base classes fixes the problem in my case.
Generally speaking it seems that the QT based classes need to be the last base class.
So in case of the example this would work:

class Foo:
    pass


class MainWindow(Foo, FramelessMainWindow):

    def __init__(self):
        super().__init__()
