Hi. I have some small problems with 0.4.

I'm running Mandrake 8.0, Ruby 1.6.4 (and 1.6.5), gcc 2.96

<SNIP>
g++ -fPIC -O3  -pipe -mcpu=pentiumpro -march=i586 -ffast-math

flscroll.cc:33:3: warning: pasting "::" and "BOTH_ALWAYS" does not give

</SNIP>

This all compiles, but those warnings look scary. Is this something I
should worry about?

But I also got the ol' rb_gc_mark problem.

<SNIP>
flwidget.cc: In function `void rb_fl_mark (Fl_Widget *)':
/usr/local/lib/ruby/1.6/i686-linux/intern.h:189: too many arguments to
function `void rb_gc_mark ()'
flwidget.cc:34: at this point in file
</SNIP>

But this seemed to be the GCC 2.96 fault.
I changed the intern.h of Ruby to read
	void rb_gc_mark(VALUE);
and the flwidget.cc in ruby-fltk to read
	rb_gc_mark( (long unsigned int)(userdata));

I know, I should update :-)

________________________

Now, as for something _functional_ I'm missing. FL_SYMBOL_LABEL.

I was hoping for find SYMBOL_LABEL constant in Fltk, as I want my
buttons to show those nice arrow pictures. When I didn't find, it I
tried this:

	10.times{|i|
	  upbutton = 
	    Fltk::Button.new( x, y ,butw, h/(4*3), '@#2<-' ).
	    labeltype=i
	}

and noticed that the second button (labeltype=1) doesn't show anything
(a.k.a. it is FL_NO_LABEL), but the other types don't appear to work.
(labeltype>5 all also go blank.)

These are my faults. I've fixed them on the cvs.

This is correct. Actually ruby-1.7 has
  void rb_gc_mark _((VALUE));
in the intern.h.

I've also added them.

Thank you!

With these, I've got my first running version of MasterMind in Ruby
using FLTK.
MasterMind is one of those games I write in every new language I learn,
to help me get a feel for various parts of the language, and in this
case Ruby-FLTK too. 

For the curious:
 http://www.stud.ntnu.no/~kentda/public/coding/ruby/projects/toys/
but the rules aren't explained in-game yet.

Ok, back to nagging :-)

I'm thinking of writing the example Editor FLTK application in
Ruby-FLTK. 
 http://www.fltk.org/doc-1.0/editor.html#editor

But when I tried to set up a MenuBar, I got stumped. I cannot find any
MenuItem class, but perhaps I don't need it? Are there any samples of
using menus and menubars in Ruby-FLTK?

Wrappers to Fl_Menu_Item have not been available yet.
But I think we can use Menu#add() method to do such
things simply. See also test/menu_bar.rb.

Hi again.

I've got most of the "Simple Text Editor" sample application in FLTK up
and running in Ruby-FLTK, however it does require the newest cvs (+
implementation of Fltk.input, which I sent a naive version of on the
devel list.)

One thing I haven't got working yet, is Alt-shortcuts. The samples show
"^n" which mean Ctrl+n, but I'm not sure how to do all the various
shortcuts that are shown in the tutorial. 
It has (FL_ALT + 's') and (FL_ALT + FL_SHIFT + 's')
	Ideally, I think it should be possible to have a method you pass in the
Fltk::ALT constant with the character to some "shortcut creator", so
that we don't end up with more 
regexp-look-alike magical character sequences ;-) 

Oh, and Kevin: Where is the Space Monkeys thingie available? It sounds
cool!

I'd like to provide the ruby-fltk with your editor.
Can I absorb it?

"#s" and "+s" mean FL_ALT + 's' and FL_SHIFT + 's' respectively.
But I fixed Menu_#add() so that we can pass an integer value
like this:

  @menu.add("file/exit2", FLTK::CTRL + ?q){ exit(0) }

This line is a part of test/menu_bar.rb I modified today.

Thank you for your advice.

I have just now released the Ruby/FLTK version. It's rough,
but works just as well as the GTK version ever did.
Actually, a bit better because I improved the command
interface slightly.

The zip file is now linked from my main page, or you can
grab it directly from
http://www.qualitycode.com/code/monkeys-fltk.zip

Oh, I didn't update the README, so ignore the stuff at the
bottom about a keyboard interface. The command to run the
game is: 
  ruby uigame.rb

Let me know if you actually play it!

Kevin
