Hello.

I have a problem with fxruby; note that plain C++ Fox works. I took a
simple example from the tutorial and here is the result:

erwan@bourricot temp $ ruby test.rb
/usr/lib/ruby/site_ruby/1.8/i686-linux/fox.so:
/usr/lib/ruby/site_ruby/1.8/i686-linux/fox.so: undefined symbol:

(LoadError)
        from test.rb:1

I read on the archives a similar problem, so I tried the following
command to check if the bindings lib fox.so is linked to fox itself:

(I use 1.0 and not 1.2 because it is required by FreeRide)

Hmmm. The reason I was asking is that if I try to decipher the name of the
undefined symbol ("_ZN2FX8FXStringC1EPKc") it sort-of looks like it's
expecting to see the FXString class in an "FX" namespace -- which wasn't
introduced until FOX 1.2.

But the short answer is, I don't know what to tell you other than "wipe out
all of your FOX and FXRuby installations (any versions) and then try again".
[I'm thinking that if this were a widespread problem we would have
discovered and corrected it by now.]

Hi,

I don't understand how to combine ImageMagick and FXImage...

The problem is that I don't get how I should tell the FXImage about my pixels...

The docs says I should either provide a FXMemoryBuffer or a String.

I've tried with all types of strings I think. Both binary (from pack)
and seperated with spaces, commas, etc, but all I get is either a grey
mass, or black with various colored pixels...

FXMemoryBuffer can't be created it seems. FXMemoryBuffer.new just blows up?!??

I guess I could save the image generated from ImageMagick and then use
the 'standard' FXJpgImage class, but I rather not...

You could create an FXImage with the right dimensions, and then
set its pixel data:


	image=new FXImage(app,pixels,IMAGE_OWNED|IMAGE_KEEP,width,height);


After which FXImage assumes ownership of the pixel array [which must have
been allocated with FXMALLOC()].  If the pixel array is not to be owned
by FXImage, then, of course, you can just omit the IMAGE_OWNED flag.

The pixel array, incidentally, is just a rectangular array of colors. 
Each color is RGBA, in that order, from low to high memory.  The FXRGB
macros are adjusted based on the machine's byte order so if you use
these macros then the memory layout of your colors will be automatically
correct.

Hope this helps,

I'm using fxruby, so it looks like this for me:

# This should create a either very dark magenta or very bright
magenta, depending on internal bitcolors:
buf = []
100.times {
  100.times {
     buf << 255
     buf << 0
     buf << 255
   }
}

transformed_buf = buf.join(" ")     # Doesn't work
# transformed_buf = buf.pack("i")   # Doesn't work either

image = FXImage.new(getApp(), transformed_buf, 0, 100, 100)

imageView = FXImageView.new(self, nil, nil, 0, LAYOUT_FILL_X|LAYOUT_FILL_Y)
imageView.image = image


All I get is a small, scrollable window in very dark grey.

> The pixel array, incidentally, is just a rectangular array of colors.

Documentation for FXRuby says it should be FXMemoryBuffer or String. :(

FXMemoryBuffer doesn't work though:
fx_image_test.rb:20:in `new': allocator undefined for
Fox::FXMemoryBuffer (NoMethodError)

And I can't figure out how to transform my Array to a proper String...

> Hope this helps,

Sadly not, I'm using the Ruby interface...

But that's not your fault. :)

I don't know how/why my message ended up on the foxgui-users mailing
list, though...

It always helps to post code to realize that you've done a mistake. :/

buf.pack("c*") works EXACTLY like I wanted it to.

Sorry for the noise... :(

Hi

any hints/suggestions for my problem of installing the 1.2.2 binary on  
windows? I have downloaded the 1.2.2 gem

http://rubyforge.org/frs/download.php/1613/fxruby-1.2.2-mswin32.gem

but it seems to be incomplete .. if I tray to do a

gem install fxruby-1.2.2-mswin32.gem it complains not finding the fox12  
library in the ext directory (see my previous email) .. I've tried to  
manually open the gem file (renamed it as a tar file and open it with  
winzip) .. it contains two other archives, one called metadata and the  
other data ..

in the data archive it appear to be the fox installation, it contains  
directories for doc, examples, lib, rdo-sources, tests and web, but no ext  
directory and no fox12.so anywhere .. in fact the gem file seems also much  
smaller than the 1.2.1 one ..

Probably I'm doing something wrong .. any help will be really appreciated,  
since I'm stuck on this problem

Thanks a lot, Riccardo

P.S.
I'm using gem 0.8.1 ..

Sorry for the delayed response. I've just uploaded a corrected version 
of the Gem file; the file size is now about 2.3 Mb.

Thanks very much for the heads-up about this problem!

Message-ID: <418DC26A.9050805@hypermetrics.com>

Question -- has anyone lately tried Tycho (tycho.rubyforge.org)
with Fox 1.2 and the corresponding latest fxruby?

I haven't tried it yet -- as I've been scared to -- but a couple
of people have told me it crashes immediately.

Latest news I have is that it crashes around line 766 in tycho.rb,
at the call to super in MyMain#create (which should of course call
FXMainWindow#create).

Any hints welcome.


Thanks,
Hal

Subject: [fxruby-users] Creating widgets after initialize of the main window
Message-ID: <opshhzvitznm4fay@mail.invitel.hu>

Hello there

I have just got into learning FXRuby, and have a problem I can not solve - last night at #ruby-lang could not help either. I'm sure you can easily solve it :)

Unfortunately I don't have the actual source code here, but the point is the following:

def ininialize(app)
   ...

   @frame = new FXVerticalFrame.new self, ...
   @btn1 = new FXButton @frame, ...
   @btn2 = new FXButton @frame, ...

   @btn1.connect(SEL_COMMAND) do |a,b,c|
     @btn3 = new FXButton @frame, ...
     puts "i'm here"
   end

   ...
end

My problem: @btn1 and @btn2 buttons are created/shown well, but the @btn3 (which I create in the select event handler of @btn1) is not shown at all, but the execution gets there ("i'm there" is printed).

I tried the following - without success:
- creating FXListBoxs instead of FXbuttons
- calling @btn3.create explicitly
- playing around with update, repaint, forceRefresh, ...

Thank you in advance.

Regards,
   Krisztian Kaldi

Calling @btn3.create should have done the trick. If you have a short example
program (not a code fragment) that demonstrates the problem, we can take a
look to see what might be going on.

Message-ID: <419C4743.3020501@hypermetrics.com>

Duh...

I installed Fox 1.2.11 and then the 1.2.2 gem -- and all seemed OK.

Then when my code did a
   require "rubygems"
   require_gem "fox"

this is what I got:

   [hal@dhcppc2 tycho]$ ruby tycho.rb
   /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:116:in `activate':  (Gem::LoadError)
   Could not find RubyGem fox (> 0.0.0)
           from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:34:in `require_gem'
           from tycho.rb:3

So I thought: I guess the gem name is fxruby?

But then I got:

   [hal@dhcppc2 tycho]$ ruby tycho.rb
   /usr/local/lib/ruby/gems/1.8/gems/fxruby-1.2.2/ext/fox12/fox12.so: libFOX-1.2.so.0:

     `require'
           from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:148:in `activate'
           from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:34:in `require_gem'
           from tycho.rb:3

So... how am I being stupid here?


Thanks,
Hal

I think the problem is that the extension module (fox12.so) can't find 
the FOX library (libFOX-1.2.so); but to check this theory, can you tell 
me the output of this:

	ldd /usr/local/lib/ruby/gems/1.8/gems/fxruby-1.2.2/ext/fox12/fox12.so

Thanks,

Lyle

Do you perhaps have an old FXScintilla, compiled against FOX 1.0, 
installed? Check to see if you have a file like:

	/usr/local/lib/libfxscintilla.so

(that may not be the exact name). If that installation of FXScintilla 
was built in the past, against FOX 1.0, that might be the conflict. In 
that case I think you'd need to rebuild FXScintilla against FOX 1.2. 
Seems like someone else has run into that problem recently.

I suspect what is happening is that when you build FXScintilla, it's 
seeing the FOX 1.0 installation (i.e. /usr/local/lib/libFOX.so) and 
linking against that instead of your FOX 1.2 installation (i.e. 
/usr/local/lib/libFOX-1.2.so). Can you send me a copy of the config.log 
file that should be sitting in your FXScintilla build directory? It's 
the file that shows what kinds of decisions the "configure" script 
while it was configuring the FXScintilla build, and it should resolve 
the question of which FOX library your FXScintilla is linked to.

Yes; this was done intentionally to distinguish between applications 
written for FXRuby 1.0 and applications written for FXRuby 1.2. See the 
change history:

	http://www.fxruby.org/1.2/doc/changes.html

and technically those instructions are not quite right; for the gem 
installation, you need to do this:

	require 'rubygems'
	require 'fox12'

A different approach (recommended by the RubyGems folk) is to just add 
"-rubygems" to your RUBYOPT environment variable so that the "rubygems" 
module is always automatically loaded when the Ruby interpreter starts 
up. If you've done that then you'd only need to do:

	require 'fox12'

> Do I have to "kill" 1.0 somehow?

You don't have to, no. They should be able to co-exist.

As of the the latest version of RubyGems, you should be able to use 
either of the following forms:

	require 'rubygems'
	require_gem 'fxruby'

or:

	require 'rubygems'
	require 'fox12'

I suppose I'd recommend the latter since that should work whether 
they've installed the code from a Gem or from some other source (like 
the source tarball, or RPA, or whatever).

I apologize for the confusion, but RubyGems has been a bit of a moving 
target over the last few months. There's still a pretty significant bug 
in RubyGems 0.8.1 that affects gem-based installations of FXRuby (or 
any other compiled extension) on Mac OS X. In retrospect it was 
probably a mistake to try to shift things over to RubyGems at the time 
that I did, but hopefully things will settle down as they head into the 
home stretch towards a RubyGems 1.0 release.

Thanks,

Lyle

OK, that confirmed my suspicion: If the FXScintilla configure script 
sees both FOX 1.0 and 1.2 installed, it goes with FOX 1.0 by default. I 
checked my FXScintilla build directory (also for FXScintilla 1.61) and 
it looks like his configure script has this option:

	./configure --with-fox-1-2

(I got this by doing "configure --help"). So I think what you might 
have to do at this point is:

  1. Re-configure FXScintilla using this switch; rebuild it and 
re-install it.
  2. Re-install the FXRuby gem, so that it links against this build of 
FXScintilla and not the old one.

Hope this helps,

Lyle

Message-ID: <41A465DA.7000201@hypermetrics.com>

I've just gotten 1.2 properly installed with Lyle's help.

I can now confirm what others have told me: My code segfaults with 1.2.

Here's an abbreviation of the code:

   class MyMain < FXMainWindow

      # other methods...

      def create
        super      # <--   [BUG] Segmentation fault on line 768
        # other code...
      end
   end

In addition, there are several hundred warnings output before that,
all of this form:

   /usr/local/lib/ruby/site_ruby/1.8/fox/glgroup.rb:17:
   warning: already initialized constant FLT_MIN


Any idea what goes on here?

If Lyle or anyone else wishes to try the code, it's downloadable
from http://rubyforge.org/projects/tycho

I don't pretend this has any urgency -- it's just a side project of
mine, if a pet one -- but I do want to move it forward eventually.


Thanks for any insight...
