fl_color_chooser with alpha channel?

[Gonzalo Garramuño]

Does anyone have one?  I want a widget like fl_color_chooser but that
allows picking/typing an alpha channel too.

Hmm, I have not compiled it in many years, but it may just work out of the box:

Thank you Matthias.  It works fine, with a small change to the include
fl_draw.h to fl_draw.H.

    I was able to get it to work too with 1.4.x; as gga says, just have to fix that fl_draw.h -> fl_draw.H.
    In case anyone's curious what it looks like:

    Apparently one can just call the function flmm_color_a_chooser() to open the
    chooser as a separate window dialog, and it blocks until the user picks something, e.g.

void show_chooser(Fl_Widget*w, void *data) {
    static double r=1,g=1,b=1,a=1;
    int ret;
    ret = flmm_color_a_chooser("Matt's Color Chooser",r,g,b,a);
    printf("Result: %d\n", ret);
    printf("    RGBA: %.2F %.2F %.2F %.2F\n", r,g,b,a);
}

It was meant pretty much as a drop-in replacement for fl_color_chooser(), so the APPI is almost the same.
