I think I've finally got it.
Thanks again - that was *very* helpful for my actual project and with regard to
former problems I was facing when drawing things in FLTK.
And thanks to Albrecht for his example code!

I tried that before and I could swear width always being 0.
But as I wrote this I tried again (on Linux) and it worked.
Perhaps it was on Windows? I'll try on Monday.
I'm guessing in the tests where you got 0,
fl_font() hadn't been set

It works as you say, but I still can't understand why this doesn't work:

I made the recommended improvements but without any effect.
On debugging I found out that the measurement of the topmost Fl_Output
widget (calling fl_measure()) sets 0 to my width variable (wi). The
measurement of the next widgets is ok.
That's why I think - but am not sure - that the reason

add a dummy Fl_Output with width = 0 and height = 0.
And now the topmost widget is measured correctly. So my application

I started with your code.
OP's wouldn't build; missing includes, std:: notation, etc.

Hi all,
I'm trying to create several Fl_Output derived controls on demand and put them
by columns into a Fl_Double_Window. The width of each Fl_Output shall go with
its value, e.g. for a value A width should be 10 and for a value
MyTestValue it should be 110.

Oops! Check the docs...
Three issues:
1)You must explicitly set wi and he to zero before you call
fl_measure(), or they will be interpreted as being width/height limits
to wrap to.
Since they appear to be stack variables here, we
