I agree with Marcus that the original multi line approach is more clear.
Also, if your goal is just to reduce the number of lines, aren't you going
to end up having to format the single functor call across multiple lines
anyways to avoid a super long line as the parameters increase?
The only benefit I can think of is that it does make it easier for you to
store and reuse widget initialisation contexts as dictionaries so that you
could stamp out different widget instances like:
widgetA = factory(**typeA)
But I don't know if that was your intended goal? You only refer to reducing
line count.
It's also easier to make a typo when you switch from calling first class
setters to custom named parameters where it would skip any unrecognised
params. Is that a consideration?
I forgot to mention that the methods are supposed to be private. So

The implementation of the functor actually doesn't need to store any state
at all. Technically those methods could be static and just get passed a
widget. It's also probably not a good idea to have it store the widget
anyways since it prevents garbage collection or could hold onto something
that gets deleted in C++.
Also it seems like your impl calls every method multiple times, since it's
doing it in a loop for the provided parameters.
