Re: [Pyfltk-user] measure_label

[Matthias M. <mm...@ma...>]

Not sure how it is implemented, but in C++ FLTK, 'w' is an in.out parameter. So you need to pass the preferred with with w, and it will return the actual width.

For Python, I would expect something line `w,h = widget.measure_label(w)`. For reference, `fl_measuer(...)` is pretty much the same call. Can you see how that one is called?
