I'm working on enabling/disabling controls, and I keep getting
exceptions like the following:

mysource.rb:262:in `enable': Expected argument 1 of type bool, but got
NilClass nil (TypeError)
        in SWIG method 'Enable'
        from mysource.rb:262

        from app.rb:188

Is there an (easy) way to help WxRuby follow Ruby's notion of truth,
i.e. everything but +nil+ and +false+ are true?

The current best workaround I have is 

  enable(... ? true : false)

but that's clunky, and I obviously keep forgetting to use it. :-)

Thanks!

These exceptions come from SWIG's default way of wrapping C/C++ methods 
that require a C boolean type.

Globally, it could be changed by altering the standard way that wxRuby 
SWIG translates methods that require a boolean. It is a pretty simple 
%typemap statement but obviously requires the whole SWIG+compiler 
set-up. However it's a change I'd be open to adding for future versions, 
as I think SWIG's approach is sometimes too class-strict for Ruby style.

For the time being, the only way would be either to add your workaround 
to a subclass of the control, so that its enable method looked like 
super(input ? true : false). Or you could do some reflection and find 
methods called 'enable' in all wxRuby classes at start-up and redefine 
them. But from experience (at least with Ruby 1.8) it does take a little 
time to cycle through all the 200+ classes.

I'm already a bit over-budget; I won't have time to set up the full
environment now.  Is there a bug-tracking system I can enter this as an
enhancement request?

That's a good idea.  For now I'll override Window#enable, and that
should take care of it for my use.

Thanks!

Subject: [wxruby-users] Expanding a flex grid sizer horizontally
Message-ID: <8AB9A8D5-84F2-4CDF-8A22-5D29EA47BDDF@simonszu.de>

Hi there,

i am trying to expand a flex grid sizer horizontally. I have a 2x2 sizer, in the left column are two StaticTexts and in the right column two TextCtrls. I'd like to expand this grid sizer so that the TextCtrls reach the right border. This is my code:

	settingsLayout = BoxSizer.new(VERTICAL)
	settingsRow = FlexGridSizer.new(2,2,10)
	settingsRow.add(consumerSecretLabel, 0, ALL, 0)
 	settingsRow.add(@consumerSecretInput, 1, EXPAND|ALL, 0)
      	settingsRow.add(consumerKeyLabel, 0, ALL, 0)
      	settingsRow.add(@consumerKeyInput, 1, EXPAND|ALL, 0)
	settingsLayout.add(settingsRow, 1, EXPAND|ALL, 3)
	self.set_sizer(settingsLayout)

Right now it is so that the TextCtrls have the same width as the StaticTexts. Can you tell me how to expand them horizontally?

Thank you.

Alex:

Thanks for the RubyForge tracker pointer.  I'll add this to the list.

FYI, I just squashed a related bug.  I was returning +nil+ when a
drag-drop operation failed, and it would crash my application.  I just
added the 

<expression> ? true : false

trick on my return value, and the crash is gone.  I assume the SWIG
solution would handle this case, too.

Thanks!

Thanks for the info. Standard SWIG covers straightforward cases (e.g. 
Ruby arguments to C++ methods). Some stuff like drag-drop where C++ code 
calls Ruby then back to C++ is more tricky and there may be unsafe 
conversions. So it would be great if you could add a couple of details 
in a bug report.

Not tested, but I think you ought to specify that the second column of 
the FGSizer should take up extra space

settingsRow.add_growable_column(1)

I realize I'm a bit late and not really solving the core issue, but: one of
the common ways to approach forcing a boolean datatype, in the rails world
at least, is to double up your boolean not operators: !!<expression>. It's a
little weird looking at first but gets the same results as (<expression> ?
true : false) with less typing.

Subject: [wxruby-users] Standard icon in custom dialog
Message-ID: <BA8CB6550BF0814CB7E3CB0F6827465CCBCE4E@SLXCG03.csw.l-3com.com>

Is there any way to grab a standard icon for a custom dialog?  I have a
message box with Wx::ICON_ERROR, and I want to add a check box to it.
The only way I know to do this is to create a custom dialog.  Then I can
use a standard button sizer to get the proper buttons, but I can't find
the error icon.

Any hints are appreciated.  Thanks!

Subject: [wxruby-users] Handling Unicode in WxRuby
Message-ID: <4E24D516.8040108@smart.net>

If I am using Ruby 1.8.7, what are some recommended practices for 
supporting Unicode within a WxRuby application?  My understanding, based 
on web research, is that I should use the multibyte module of Active 
Support in order to add Unicode support to Ruby 1.8.7 (Ruby 1.9 includes 
Unicode support natively).

Generally, I have read the recommendation that it is best to do 
everything in UTF-8.  I can try to do so, but am wondering how WxRuby 
handles strings that are passed to set properties, e.g., the text of a 
label.  Does this library expect strings to be in a certain encoding? 
How can UTF-8 be specified to WxRuby?

I'd highly recommend using Ruby 1.9. It's much more painless.
Back in times before I switched to Ruby 1.9, I used the Iconv module
(stdlib) to convert all my strings to UTF-8. If I remember correctly, it
worked like this:

require "iconv"
ary = Iconv.iconv("UTF-8", "yoursourceencoding", "1st_string", "2nd_string")

wxRuby expects your strings to be UTF-8-encoded, there's no way to tell
wxRuby you want to use another encoding AFAIK. wxRuby just passes the
strings directly to the underlying wxWidgets, resulting in incorrect
characters being displayed in the final GUI.

bonjour.
J'utilise "HtmlEasyPrinting.new()" pour imprimer des pages via "htmlwindow".
Quand je visualise mes pages avec "preview_text", la mise en page apparait correctement et les urls aussi.
Mais par contre quand j'imprime les pages, les urls n'apparaissent pas sur les photocopies.
Que faire pour que les urls soit pr?sent lors de l'impression des pages?
merci
