This ought to pretty much Just Work.

Note that when you are designing your GUI, fluid shows the derived widget in a floating window, but that's not necessarily strictly representative of how it will be manifest in your code...

So, in fluid, you go

New->Code->Widget Class

and this pops a floating window that you design your widget in (but this need not be a floating window once your code is made.)

Now select the new widget in the fluid browser and get its properties up:

On the C++ tab, set the name to whatever's appropriate (let's say MyGroup for now), and ensure the Class field is set to Fl_Group.

Then on the GUI tab, make sure the width and height are what you want, and make sure the "Relative" toggle button is selected.


Now on your main window, drop a regular Fl_Group of the correct size, and get its properties dialog up.

On the C++ tab, set Class: to MyGroup, and on the GUI tab make sure the size and position are correct.


Rinse and repeat for additional instances of your derived group.

Have fluid generate the code; compile; test.

That ought to be about it...


I'm probably explaining this badly; here's one I made earlier...


derived_grp.fl


# data file for the Fltk User Interface Designer (fluid)

header_name {.h}
code_name {.cxx}

Fl_Button {} {
label {A Button}
xywh {25 25 70 35}
}
}

Function {} {open
} {
Fl_Window main_win {
label Main open

Fl_Group dervied_1 {open

class derived_group
} {}
Fl_Button {} {
label Quit
callback {main_win->hide();} selected
xywh {90 515 64 35}
}
}
}
