Might be useful to us to have more context for what you are actually doing; do you have some small, compile-able code samples, for example, that would illustrate what you are doing, and perhaps some descriptions of what effect you want to attain...

In general, if no widget in a container (i.e. a group or window, usually) is identified as the resizable, then any resizing it shared out amongst all the widgets.

The "usual solutions" are to either make the window non-resizable, or to assign a widget to "consume" the resizing (sometimes a hidden widget in the group is used to achieve this.)

There's a How-To that might help a bit : https://www.fltk.org/articles.php?L415

Thanks Ian MacArthur. Gonzalo Garramuño helped me get to a solution, similar to your suggestions.

I have a suggestion for FLTK maintainers like Ian MacArthur I guess. Why don't we have something like this implemented (like Constraint Layout in Android):

CoordinateManager().set(addrSubject)

  .leftTo (DIRECTION d, void* addrBenefactor, bool stretch = false)

  .rightTo (DIRECTION d, void* addrBenefactor, bool stretch = false)

  .topTo (DIRECTION d, void* addrBenefactor, bool stretch = false)

  .bottomTo (DIRECTION d, void* addrBenefactor, bool stretch = false)

  .centerTo (void* addrBenefactor)

  .centerTo (int x, int y, int x2 = 0, int y2 = 0)

  .leftTo (int x, bool stretch = false)

  .rightTo (int x, bool stretch = false)

  .topTo (int y, bool stretch = false)

  .bottomTo (int y, bool stretch = false)

.set(addrBenefactor)

  .leftBy (int n, bool stretch = false)

  .rightBy (int n, bool stretch = false)

  .topBy (int n, bool stretch = false)

  .bottomBy (int n, bool stretch = false)

.render();

Just x, y, w, h manipulations.

The closest equivalent in fltk would probably be Fl_Flex - does that address your issues?

Emmm. I am OK. Thanks.

I have added a fluent interface to Fl_Flow that is similar to what you want. Give it a look:

Thanks Jose... To be downloaded later.
