My goal here is to avoid having to wright multiple lines to set a widget.
What’s wrong with using multiple lines to initialise a widget?
Equivalent without functor (this is what I want to avoid)
I don’t have 40 years of experience, but frankly that example is a lot
easier to read IMO. Have you considered subclassing?
buttonA = MyPushButton()
class MyPushButton(QtWidgets.QPushButton):
def __init__(self, text, parent=None):
super(MyPushButton, self).__init__(text, parent)
self.setObjectName("myPushButton")
self.resize(60, 20)
