Reordable_list_widget_example does not run with qtpy5

[DanicaSTFC]

While testing #146 with qtpy5, and running the example file /eqt/examples/reorderable_list_widget_example.py, the following error appears

\eqt\examples\reorderable_list_widget_example.py", line 40, in <module>
  window = MainUI(title="ReOrderableListWidget")
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "\examples\reorderable_list_widget_example.py", line 17, in __init__

  verticalLayout.setContentsMargins(1, -0.9, 1, -0.9)
TypeError: arguments did not match any overloaded call:
setContentsMargins(self, left: int, top: int, right: int, bottom: int): argument 2 has unexpected type 'float'
setContentsMargins(self, margins: QMargins): argument 1 has unexpected type 'int'

Check that the class itself works.
