Group inside flex generates different from fuild.

Here is the fl sample:

# data file for the Fltk User Interface Designer (fluid)
version 1.0400
header_name {.h}
code_name {.cxx}
class UserInterface {open
} {
  Function {make_window()} {open
  } {
    Fl_Window window {
      label Sample open
      xywh {321 208 400 300} type Double resizable visible
    } {
      Fl_Flex flex {open
        xywh {0 0 400 300} type HORIZONTAL set_size_tuples {1  0 200 }
      } {
        Fl_Group group {open
          xywh {0 0 200 300}
        } {
          Fl_Button button {
            label button1 selected
            xywh {10 10 180 25}
          }
        }
      }
    }
  }
}

It generates

    let mut window = Window::new(321, 208, 400, 300, None);
    window.set_label("Sample");
    window.end();
    window.set_type(WindowType::Double);
    window.make_resizable(true);
    window.show();
    let mut flex = Flex::new(0, 0, 400, 300, None);
    flex.end();
    flex.set_type(FlexType::Row);
    window.add(&flex);
    let mut group = Group::new(0, 0, 200, 300, None);
    group.end();
    flex.add(&group);
    let mut button = Button::new(10, 10, 180, 25, None);
    button.set_label("button1");
    group.add(&button);
    flex.set_size(&flex.child(0).unwrap(), 200);
    flex.recalc();
    Self {
        window,
        Flex
        group,
        button,
    }
    }
}

I tried if flex.add(&group); generate after group.add(&button);, the result will be the same as in fuild:

I've pushed a fix. Can you try with the main branch?

[felixmaker]

It works! Thank you!
