fxruby users - May 2006 - FXRuby 1.6.0 Now Available

All,

FXRuby version 1.6.0 is now available for download from this page:

	http://rubyforge.org/frs/?group_id=300&release_id=5497

This is the first release of FXRuby that is compatible with the FOX 1.6 
library. Although FXRuby 1.6 has undergone a good bit of pre-release 
testing, this should still be considered an "unstable", 
not-ready-for-production-use release. Also note that you should be 
using FOX 1.6.5 or later due to some important changes made in that 
release of FOX.

For a summary of the changes in this release of FXRuby, please see this 
page:

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

As usual, the code is provided as a Win32 installer or a binary Gem 
(both compatible with the latest One-Click Installer for Ruby 1.8.4), 
as a source gem, and as a source tarball. For instructions on compiling 
FXRuby from source, please see:

	http://www.fxruby.org/doc/build.html

And as always, the FXRuby home page is here:

	http://www.fxruby.org

Enjoy,

Lyle

Remember to change any require statements to point to ''fox16''
instead
of ''fox14''. Otherwise, you''ll still be using FXRuby
1.4!

As usual, please use the bug tracker at RubyForge to report any bugs or 
make feature requests.

My bad. Check it again (may require a browser refresh).

For some reason, Jeroen hasn''t updated the FOX home page download links
with this one -- but it''s there in the usual place.

I wasn''t aware there was a FOX 1.6.5 out there... !?

lyle,

i have a problem installing fxruby 1.6 gem on linux. the fox16.so
compiled fine. everything seems to be in its place but require "fox16"
doesn''t seem to work.

henon at golem:~$ irb

here are the last lines of the gem installation process. it says that
there is nothing to do for make install. is this ok?

fxruby 1.6 compiled without errors too.
just the require fails to load the library somehow...

any clues?

I just did a fresh install on Fedora Core 4 and everything works as 
expected. Could you send me a copy of the file:

	/usr/local/lib/ruby/gems/1.8/gems/fxruby-1.6.0/ext/fox16/gem_make.out

It may be in a slightly different location, depending on where you''ve 
installed Ruby. I''m not sure what I''m looking for, but I can
at least
see if there are any obvious differences between my copy of 
gem_make.out and yours.

Thanks,

Lyle

Charles, I don''t think this difference is significant; it just 
indicates that your Ruby is installed under /usr instead of /usr/local.

I''ve compared both yours and Henon''s gem_make.out files to
mine (which
was for a build under FC4) and the only obvious differences are:

+ For the Debian builds, the "platform" part is "i486-linux"
instead of
"i686-linux"
+ For the Debian builds, "-lruby1.8" is included in the final link
step
(the one that builds fox16.so). It''s not included in mine.

Neither of these differences are ringing any bells for me, and so I 
don''t know what to tell you to do. I suspect that there''s
something
"interesting" about how the version of Ruby that''s bundled
with Debian
is built, but I don''t have access to that operating system.

Are any other Debian users reading this? Any clues?

Well, if you just did "configure; make; make install", then FOX got 
installed in /usr/local/lib and not /usr/lib.

If that''s the case, the solution to your problem can be found on this 
page from the FXRuby User''s Guide:

	http://www.fxruby.org/doc/gems.html

Hope this helps,

Let me be sure I understand this (I also did a "make intall").
The files are in:
/usr/local/lib/libFOX-1.6.a
/usr/local/lib/libFOX-1.6.la
/usr/local/lib/libFOX-1.6.so
/usr/local/lib/libFOX-1.6.so.0
/usr/local/lib/libFOX-1.6.so.0.0.4
Isn''t this one of the "few standard places"?

I''m sorry, I don''t understand the question. A "standard
place" for what?

Yeah, that''s talking about looking for the include files (e.g. in 
/usr/include/fox-1.6, /usr/local/include/fox-1.6, etc.) so that it can 
build the FXRuby extension.

Right, the FXRuby installation process doesn''t attempt to automatically
"fix" your ld.so.conf file settings that control how shared libraries 
are loaded.

Have you filed a bug report about this yet? I''m not remembering this 
one and I don''t (think) I see it in the list at:

	http://rubyforge.org/tracker/?atid=1223&group_id=300&func=browse

If you''re pretty sure it''s some kind of FXRuby bug, please do
go ahead
and file a bug report for it.

Thanks,

Lyle

I''m trying to develop a GUI that combines features of
the foursplit.rb and shutter.rb examples.
So there is a bar of ShutterButtons to the left,
and a set of four FX4Splitter elements to the right
of the screen. 
Thanks to expert help from Lyle, it''s now possible to
''expand'' any of these elements to full size of the
right pane.
Now, I need to add the possibility to switch between
different layers of the right pane, just like in the
shutter.rb application, where you press one of the
ShutterButtons on the left to have that behaviour.

In my code, I set a variable @shutter.current =0, etc..,
like this

...
big_splitter = FXSplitter.new(self, (LAYOUT_SIDE_TOP|LAYOUT_FILL_X|
      LAYOUT_FILL_Y|SPLITTER_TRACKING))
...    
@shutter = FXShutter.new(big_splitter, nil, 0,
      FRAME_SUNKEN|LAYOUT_FILL_X|LAYOUT_FILL_Y,
      0, 0, 0, 0, 0, 0, 0, 0, 0, 0)
...
@switcher = FXSwitcher.new(big_splitter,
      FRAME_SUNKEN|LAYOUT_FILL_X|LAYOUT_FILL_Y, 0, 0, 0, 0, 0, 0, 0, 0)
splitter = FX4Splitter.new(@switcher,
      LAYOUT_SIDE_TOP|LAYOUT_FILL_X|LAYOUT_FILL_Y|FOURSPLITTER_TRACKING)
shutterItem = ShutterItem.new(@shutter, "Files, data, and pictures",
nil, LAYOUT_FILL_Y)
    ShutterButton.new(shutterItem.content, "Expand dirlist",
big_folder).connect(SEL_COMMAND){
     @switcher.current=0
     splitter.handle(self,FXSEL(SEL_COMMAND, FX4Splitter::ID_EXPAND_TOPLEFT),
nil)}
    ShutterButton.new(shutterItem.content, "Expand cell file editor",
pens).connect(SEL_COMMAND){
     @switcher.current=0
     splitter.handle(self,FXSEL(SEL_COMMAND, FX4Splitter::ID_EXPAND_BOTTOMLEFT),
nil)}
    ShutterButton.new(shutterItem.content, "Expand tuning curve plot",
messypaint).connect(SEL_COMMAND){
     @switcher.current=1
     splitter.handle(self,FXSEL(SEL_COMMAND, FX4Splitter::ID_EXPAND_TOPRIGHT),
nil)}
    ShutterButton.new(shutterItem.content, "Expand reconstruction
plot", drawing).connect(SEL_COMMAND){
     @switcher.current=2
     splitter.handle(self,FXSEL(SEL_COMMAND,
FX4Splitter::ID_EXPAND_BOTTOMRIGHT), nil)}
    ShutterButton.new(shutterItem.content, "Show all four",
monitor).connect(SEL_COMMAND){
     @switcher.current=3
     splitter.handle(self,FXSEL(SEL_COMMAND, FX4Splitter::ID_EXPAND_ALL), nil)}
    
Then, I get the error below.
What is the problem here ?

Thank you very much in advance,

Axel

it''s normal to get some errors when writing a program. but a
programmer must know how to deal with them. i give you some help so
that you can help yourself in future:

have a look at the error msg: it tells you exactly where in your
source code the error happened. then add some lines that output the
values to see what''s going on.

in your case you set the current item of the switcher to an index that
does not exist. so just output the index with puts to see what is the
error in your program.

try that first. if you have more questions i will answer them.
hope that helps,
