Hmm, yes, I can replicate in fltk2 current:
#include <fltk/Window.h>
#include <fltk/Widget.h>
#include <fltk/run.h>
using namespace fltk;
int main() {
Window *window = new Window(300, 180);
window->color(0x0);
window->show();
return run();
}
FLTK 1.x works fine, so either it's a bug,
or something odd about FLTK2.
Setting it to 0x1 makes it red (expected),
and the test/color_chooser shows the 0 color to be black,
so unless there's a weird reason, it should work.
Will wait for someone who knows FLTK2 better than I to reply.
