Hi everybody, I''m Reginaldo (from Brazil), and this is my first message at fxruby-users list (actually, I''m "digging" FXRuby and its API only four days ago). My interest is to popularize desktop development with Ruby here in my region and I think FXRuby will help me very much in this task. So, starting it, how could I translate FXRuby constant messages (texts of buttons and labels of a FXPrintDialog, for example) from english to any other language (portuguese, spanish, french, italian, german)? Should I use a FXTranslation instance? How can I use it? Thanks in advance, Reginaldo Francisco naldo_ds at yahoo.com.br

Reginaldo, I do the same thing Paul does, slightly differently. I have a yaml
file with the different languages describing a two-levels hash :
language => {name => string}
Then I read the file, build @strings = hash[language], and then use
@strings[name].
Paul, I always work in ruby 1.9 and UTF8 (code file and data files), and my
files contain accented letters of all kinds. Why do you need bother with U+? ?

Hello Reginaldo, I faced a similar problem when designing an app a few months
ago. I solved it using 2 tricks.
The first was to take ALL the strings out of the app script/code and put them
into a separate strings file. Then from the main app I call the strings file
and all of the elements use the variables instead. This way I can change the
strings and labels to be whatever I want (in whatever language I want) and I
don''t have to update the app - just change the strings file.
The second problem was how to print special characters. I don''t know
what FXTranslation instance is, so I didn''t use that. In the FXRuby
examples folder I found a script called "unicode.rb". On my windows
box, the path is: C:\ruby\lib\ruby\gems\1.8\gems\fxruby-1.6.12-mswin32\examples
I copied the module from unicode.rb into my app and modified the strings files
to include a ''u'' at the start of the lines with unicode
characters. There might be other ways to do this, but I''m okay with
this solution for now. The strings aren''t so easy to read with the
"U+0000" for every accented character, but it worked so I moved on.
I''ve included some sample scripts below. Try them to see if it works
for what you want to do.
Hope this helps. Let me know if you find a different way to do this.
Cheers. Paul.
------- File 1: strings_PT_BR.rb -------
$app_title = u"OlU+00E1"
$button_label = u"&OlU+00E1 mundo!"
$another_label = "This string has no accented characters and so it
doesn''t have a ''u'' before the quotation marks."
# end of file
------- File 2: hello_i18n.rb -------
require ''fox16''
include Fox
# Accented Unicode characters need special handling to display correctly in the
UI:
require ''jcode''
$KCODE = ''UTF8''
module Kernel
def u( str )
String.new
str.gsub(/U\+([0-9a-fA-F]{4,4})/u){["#$1".hex
].pack(''U*'')}
end
end
# load the strings:
require "strings_PT_BR"
application = FXApp.new($app_title, "FoxTest")
main = FXMainWindow.new(application, $app_title, nil, nil, DECOR_ALL)
FXButton.new(main, $button_label, nil, application, FXApp::ID_QUIT)
application.create()
main.show(PLACEMENT_SCREEN)
application.run()

I don''t think that''s what Reginaldo meant.> constant messages (texts of buttons and labels of a FXPrintDialog, for example)(I don''t know how to do it myself, just pointing out) -- Matma Rex - http://matma-rex.prv.pl/
This was an interesting question, what it looks like happens (atleast for
FXPrintDialog) is use the FXTranslator object.
--- C++ snippets ---
/* FXPrintDialog.cpp */
FXGroupBox *dest = new FXGroupBox(contents, tr("Print Destination"),
GROUPBOX_TITLE_LEFT|FRAME_RIDGE|LAYOUT_FILL_X|LAYOUT_FILL_Y,0,0,0,0,
10,10,5,5 10,5);
---- Looking through the tr() functions appears to do this: ---
/* FXWindow.cpp */
const FXchar *FXWindow::tr(const FXchar *message, const FXchar* hint) const
{
FXTranslator *translator = getApp()->getTranslator();
if(translator){
return translator->tr(getClassName(), message, hint);
}
return message;
}
--- Translator tr() ---
/* FXTranslator.cpp */
const FXchar *FXTranslator::tr(const FXchar* context,const FXchar* message,
const FXchar* hint) const {
FXTRACE((200,"tr context ''%s'' message:
''%s'' hint:
''%s''.\n",context,message,hint?hint:""));
return message;
}
------------------------------------
Ok, so looking through that it doesn''t seem to actually map anything...
(This was fox-1.6.35 source code.)
So, I''m not really sure how to do translations on const values. Someone
with
more experience in the Fox/FXRuby libraries might be able to guide you
though. Glancing through the FXRuby source I don''t see anything
additional
or different being done for the FXTranslator object. but that''s just a
glance.. Further investigation could yield something else.
I hope this helps in some way.
Thanks,

Thanks Paul and Michel, your resource string file solutions are very interesting and i''ll certain use them at some moment in my projects, but what i really want (thanks Bartosz) is to modify the content of a FXPrintDialog (e.g. I''d like to change english caption texts of buttons, labels, groups like "Print", "Pages", "Size" to portuguese expressions "Imprimir", "P?ginas", "Tamanho"). The problem is that I don''t have access to those widgets on the FXPrintDialog public interface (In the file C:\Program Files\Ruby\lib\ruby\gems\1.9.1\gems\fxruby-1.6.20-x86-mingw32\swig-interfaces\FXPrintDialog.i they seem to be private attributes) Is there any manner to do that? P.S. in my last post i was trying to mention FXTranslator, and not FXTranslation. Does anybody know something about it?

Further investigation could yield something else.It''s that Joey, I did not find anything to do that, even how to use a FXTranslator! Reginaldo Francisco naldo_ds at yahoo.com.br
After further investigation, it''s as easy as this:
require ''fox16''
include Fox
# Create a Translation Class
class ExampleTranslator < FXTranslator
# tr() is called to translate the text
# c = context
# m = message
# h = hint
def tr(c, m, h)
# here you would probably do something like Paul did with a file to map
stuff, but for an example I just matched on
# one string.
if(m == "Print Destination")
# if text matches "Print Destination" translate to
"Something totally
different"
return ("Something totally different")
end
# otherwise we just return the message.
return (m)
end
end
# End example Translation class.
# Basic stuff..
app = FXApp.new("Test", "Test")
# Set the translator for our application to be our Translator
app.translator = ExampleTranslator.new(app)
# More basic stuff.
win = FXMainWindow.new(app, "Test App", :opts => DECOR_ALL)
pd = FXPrintDialog.new(win, "Test")
app.create
win.show
pd.show
app.run
--------------------------------------------
I realized after sending my email that the tr() function in FXTranslator was
virtual, and intended to be overwritten
by self-written algorithms.
Good luck :)

Hello Michel, I don''t want to bother with the unicode table codes. I just followed the example from the unicode.rb script (from Ruby 1.8) and since it worked I moved on. I''m still working on getting the main guts of the app working, so i haven''t had a chance to go back to the strings and find a better way of doing it. I have taken a break from working on my app for a few weeks now. I am interested in your yaml solution. Could you please send me some simple examples - like the "hello world" one I sent in my previous post? That would be great. I''d like to avoid using the unicode character codes in my strings file if I can. Thanks. Cheers! Paul. (P.S., Sorry Reginaldo that I didn''t understand your problem correctly.)

Paul,
First I have a labels.yaml file looking like
## YAML
---
fr:
:entry: ''Marche/Arr?t''
:pages: ''Pages''
<more>
en:
:entry: ''GO/STOP''
:pages: ''Pages''
<more>
I load it with
labels = nil
File.open(this_file,?r:utf-8?){ |f| labels = YAML.load(f) }
I fix the language
@strings = labels[?fr?]
Then I use for instance FXLabel(@strings[:entry] ?.)
Actually, the chosen language also comes from a user config file (another YAML
file)
@strings = labels[config[?language?]]
Two comments on YAML.
First, you always can choose between Strings and Symbols for keys and values. As
you see, I mixed Symbols for labels and Strings for the language key. It looks
strange. The reason is that *I* write the label file and Symbols are neater and
more rubyesque, but *the user* has to write his config file and is seems simpler
to have him write
language: en
than
language: :en
or even
:language: :en
The second remark is a small trick. I always forget the precise syntax of a YAML
file. So I open irb, type for instance
{ a => { :b => c}}.to_yaml and look.
By the way, you may have to ?require ?yaml??.
A last word. I have been using FXRuby for more than two years. One thing to
remember : when after a change, suddenly nothing appears on the screen when you
start your app, it means you forgot to ?create? something (font.create,
canvas.create, image.create ?).
I hope this helps.
Michel
