Re: [fltk.general] Automatically resize buttons? - Forums

Thanks. I've noticed that widget->measure_label() and fl_measure() have the same value, which isn't correct. fl_text_extents() has a different value which is closer, but still isn't the correct value. Do you know why this is?

You can always measure the text (label) size with fl_measure() or
fl_text_extents(), then set the sizes accordingly.

If this doesn't answer your question I may have misunderstood what
you're looking for.
