Hi, There appears to be an error in the loading of .ui files in PyQt5. Please try the attached example.
Error message:
Traceback (most recent call last):

prop_name[1:]))(prop_value)
AttributeError: 'QHBoxLayout' object has no attribute 'setMargin'
The log_window.ui instantiates a QHBoxLayout, with all margins set to the same
value. This makes
the uic module try to set a "margin" property, which doesn't exist.
Setting one of the margins (for example "leftMargin") to a different value
works.
