[ruby-fltk-users] [REQUEST] test ruby-fltk-0.5

[Takaaki T. <tt...@kt...>]

立石です．

ruby-fltk-0.5を今週か来週にはリリースするつもりでいます．
今回は，ソースとcygwinのバイナリに加えて，mingw版バイナリも提供
するつもりです．また，OpenGLモジュールともとりあえずうまく連携
できるようになりました．
結構変更が多くなったのでcvsにアクセスできる人は一度テストして頂
けると嬉しいです．mingw対応については今回が初めてですので，一応
現時点でのバイナリを以下のURLにて公開しておきます．このruby-fltk
はOpenGLに対応させて作成し，またopengl拡張モジュールも含まれてい
ます．このため，opengl32.dll,glu32.dll というDLLが必要になります．
これらは http://www.opengl.org/ からとってくることができます．

[mingw版ruby-fltk]
http://ruby-fltk.sourceforge.net/archive/ruby-fltk-20011205.mingw.zip

時間があればよろしくお願いします．

[ruby-fltk-users] [REQUEST] test ruby-fltk-0.5

[Takaaki T. <tt...@kt...>]

Hello,

I'll release the next version 0.5 in this week or next week. So I
hope you to test latest sources on cvs.
This version can work with OpenGL extension module for ruby.

Also I will distribute binary packages for mingw and cygwin including
OpenGL extension module which is provided by the other.
There is the preview release of mingw version of ruby-fltk at:
  http://ruby-fltk.sourceforge.net/archive/ruby-fltk-20011205.mingw.zip.
  (requires opengl32.dll and glu32.dll)

Thank you.
I will release the version 0.5 after fixing this problem.
I will check it with fltk-1.0.11 and fltk-1.1.0b6.

[ruby-fltk-users] ruby fltk crash in file browser

[<sz...@t-...>]

I downloaded today the latest sources of fltk and ruby-fltk.

I am using Suse Linux 7.3 (Kernel 2.4.10), ruby-fltk-0.4, fltk-1.1.0b6 and
configured the ruby fltk with the option --disable-gl (otherwise there were
unresolved symbols in the fltk so).

I tried some of your examples, and if I click around a while in the
file browser, then it crashes with the following trace:

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

I cleaned it up, fixed the shortcuts and added some more comments.
 http://www.stud.ntnu.no/~kentda/public/coding/ruby/projects/toys/

But, it seems that the "&Search" blocks the usage of Alt+Shift+S for
"Save As". I think this is a "bug" in the original FLTK Editor sample,
thou I haven't tried it in a while.

I'm also not all sure on the usage of "setup_menubar", where I made a
helper function that makes the construction of the menubar look as much
as C++ as possible, to avoid repeating myself. ("File", "File/Open",
"File/Save"...etc)
	I think it is a nice thing, but I've been using FLTK from C++ before,
so that has made me somewhat brain-damaged :-)

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.

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

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.

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?

This is correct. Actually ruby-1.7 has

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

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.)

I guess it was caused by missing MANIFEST file.

That sounds great to me. Unfortunately, I know almost
nothing about packaging, so someone other than me would
have to take care of this.

[ruby-fltk-users] Compiling in as a static Ruby extension...

[Kent D. <ke...@st...>]

Hi.

I'm trying to get Ruby 1.6.5 up and running on my Agenda VR3, with more
extensions than last time.

I copied the ruby-fltk (v0.3) into the ext/ folder, added ruby-fltk to
the ext/Setup and ran ./configure --with-static-ext in the ruby
directory, and them make.

I noticed that Ruby-FLTK isn't configured nor compiled when I do this.
(I also added XMLParser, for which the same procedure worked.)

Also, there are some hard-codings in the Makefile, that makes it
necessary to edit the makefile to cross-compile. (I use "export
CC=mipsel-linux-gcc", which doesn't work with the current Ruby-FLTK
makefile, since it defined CC directly)

Would it be worth the effort to change the make config of Ruby-FLTK to
work "magically" with the ruby compilation configuration, such as
XMLParser aparently does?

Well, the problem was, that transactionlist is a Fltk::HoldBrowser,
which has one callback, but a list of entries.

Maybe I've misunderstood Fltk on this part, since the obvious, useful
thing for me when I have a select callback, is the structure it
represents and not some toplevel object assosiated solely with the
Browser... If I think hard about it, I realize that it would break the
way callbacks work everywhere else in FLTK where 1 widget -> 1 callback
-> 1 user data.

I'll buy that now. When I read "void * pointer can be used by callbacks"
before I just assumed that it was the closest pointer to the callback,
the one it gets as an argument... I'm off to kick myself a bit now :-)

Here is a part of FLTK manual:

  Each line contains a null-terminated string of text and a void * data pointer.
  The text string is displayed, the void * pointer can be used by the callbacks
  to reference the object the text describes.

If I don't misunderstand, I think this description mention
something like "a.data(a.value)" in your code,
and the void * pointer (= "a.data(a.value)") *can* be used
in the callback block.

  @transactionlist.callback do |a,b| 
    puts a.value.to_s + ":" + a.data(a.value).to_s + ";" + b
  end

But I don't be assure of my thought.

[ruby-fltk-users] Fltk::ListBox and Fltk::HoldBrowser

[Kent D. <ke...@st...>]

Hi.

I just started playing around and changing the ListBox to accomodate my
needs.

When I did that, I noticed something that appears to work not quite as
FLTK does when you're using C++, and confused me for a few seconds :-)

After populating the HoldBrowser with data...
	@transactionlist.add("Some text", objectItRefersTo)

And setting up a callback:
	@transactionlist.callback do |a,b| 
	    puts a.value.to_s + ":" +
	      a.data(a.value).to_s + ";" + b
	end	  
...I still get b==nil. Its not an immediate problem, as I can get the
data thru the browser object, but since most Fltk callbacks use the
idiom of a widget pointer and a void pointer as arguments in C++, this
caught me by surprise. 

Reading /ruby-fltk/doc/en/guide.txtand especially 3.2 seems to be
somewhat misleading on this subject, as it states that only the data
should be passed. I'm assuming it should say that the widget itself and
the data will be passed. (Or is this changing?)

That's a great idea (if I understand you correctly). We
could have a method, something like Fltk::default_fontsize,
which would return the default, or allow you to set a new
default. All widgets that got created could automatically
invoke fontsize with this value.

I think we would have to implement this in C++, and not in
the Ruby layer. We could easily add it to our contructor
body, since we only have a couple of them. And the Fltk
initialize could either pick a default default, or create a
raw Fltk widget, ask for the fontsize, and then destroy the
widget.

At some point, we could also add features to set default
colors and other options this way. Of course, with Fltk2,
themes should solve all of this, so we don't want to do too
much with it right now.

What do you think?

Kevin

P.S. to Kent: Thanks for the code contribution! One of our
goals was that it be quick and easy to enhance and modify.

FLTK has the fl_font() which is used for setting
the font's face and size. Is this what you want?
But Ruby-FLTK don't provide it yet.

# Thank you for Input_#textsize. I've added it now.

Fixing that wasn't too hard:
