try
wnd->resizable(wnd); // the window itself
wnd->init_sizes(); // reset internal sizes array
instead.
Maybe you could/should also call wnd->size_range(...), but I don't know without
further analysis or testing.
[more code snipped]
If you could manage to post a complete, self-contained, compilable example
(with
fltk-config --compile full.cxx), then it would be much easier to help you ;-)
BTW.: _Currently_ (!) it's a bad idea to remove the resizable widget from a
group
without calling init_sizes() (or even delete() it!), because there seems to be
a
bug that the group or window doesn't adjust the sizes array accordingly. I
remember an STR filed for FLTK 2.0, but this is true for 1.x as well (it's on
my
todo list).
