Thanks. This should be fixed now.

I can't get used to the fact that in "D", you can't compare pointers if one of them may be null:

class Fl_Window {
  ...
};
Fl_Window first_window, this_window;
if (first_window==this_window) ...

Now if first_window is null, I get a crash that I would not get in C++. Ah well ;-)

Heh, well, == is for value comparison (and is implemented (for objects) like
foo.equals(bar)), is for pointers :)

if (foo is null)

Thanks. Removed.

Which ones? In the Carbon headers? Or in FLTK?

Doh! Of course! Stuff like that is the reason to learn "D", but the transition time is always painful, I guess.

BTW: I added drawing of all boxtypes and a mostly working single line text input widget.

Please folks, keep on testing - and maybe even contribute fixes... .


Thanks,

Carbon. I haven't seen the FLTK code yet, but I suppose you're doing the same, so the same suggestion applies.

"boxtype" seems to be working for drawing at least

Did you have some kind of bug tracker for d-fltk ?

Try "make clean" before each new "make".

I did. But "button" still crashes, rev. 5316

Oh, yes, I had that one before. "make clean" did not clean every file. I just checked in a better attempt at the Makefile.

make clean; make

should now fix this problem.

Is there something like a "makedepend" for "D"?

Yes, Matthias ~ it's called Build, and it effectively adds each import to the compilation list. You can find Build on dsource.org
