Fl_Input text size and height

[W. B.]

I have a Fl_Table of widgets - let's say Fl_Input widgets.

The Table resize function is written so the table automatically resizes with Window width, and it's widgets resize accordingly. So I have some rows set to adjust their length. The same is done for the height of the widgets - multiline Fl_Inputs are taken into account and the row-sizes are adjusted.

It works pretty well with "normal" multiline Fl_Inputs by calculating the needed height and width by fl_measure - the newlines or empty lines are taken into account.

Is it possible to do the same with "wrap" Fl_Inputs? fl_measure looks only for newlines...

-> I need to calculate the "full needed" height of a "wrap" Fl_Input - the width of which is known/calculated before

I hope it's understandable what I mean

I'm on my phone so can't easily check, but ISTR that if you pass fl_measure a non-zero width, it will try to measure the height of wrapped to that width...

Or I may be misremembering and that's nonsense: but check out what the docs say, just in case!

Unfortunately not, at least not for me. What do you mean with /"wrap"
Fl_Input/ ? This is not a term used in FLTK and FLTK Fl_Input widgets
don't wrap text AFAICT.

Regarding fl_measure(): you can initialize the argument 'int &w' with a
value other than 0 to wrap the text virtually within that width when
fl_measure() calculates the effective width and height.
