The fltk-flow's discuss from fltk-rs

got a problem with Flow::default_fill() on your example..

Hi,
just tried the example on the front page of fltk-flow, but it doesn't compile because of this error :

   Compiling fltk_tst_flow v0.1.0 (C:\Data\Dev\rust_tst\fltk_tst_flow)
error[E0599]: no function or associated item named `default_fill` found for struct `Flow` in the current scope
  --> src\main.rs:10:26
   |
10 |     let mut flow = Flow::default_fill();
   |                          ^^^^^^^^^^^^ function or associated item not found in `Flow`
   |
   = help: items from traits can only be used if the trait is in scope
help: the following trait is implemented but not in scope; perhaps add a `use` for it:
   |
3  | use fltk::prelude::WidgetBase;
   |

For more information about this error, try `rustc --explain E0599`.
error: could not compile `fltk_tst_flow` due to previous error

what did I miss ?
thanks..

Broken

cfl_widget.hpp was moved to the source directory in more recent versions of cfltk so there is no way to instantiate the Widget_Derived template necessary for WIDGET_CLASS and WIDGET_DEFINE. If cfltk was meant to allow creation of custom wrappers that change totally broke it.
