Apparently, there is a JAWS bug that causes a weird lockup when the
console version of the Ruby interpreter is run, ruby.exe. This does not
happen, for example, with NVDA. Try running the GUI-only version of the
interpreter, rubyw.exe. For example,
Rubyw.exe test.rb
Or if the .rbw extension is associated with ruby.exe, try just entering
Test.rbw
If anyone has ideas on how to resolve this JAWS problem, e.g., via a
scripting change, please let us know. I am copying this to the JAWS
scripting list in case anyone there has suggestions as well.

Subject: accessible wxruby
Hi,
If wxruby is accessible why might this program not talk?I'm using JFW
11.
require "rubygems"
require "wx"
class MyFrame < Wx::Frame
def initialize
super(nil, #Parent
:title => "RadioBox Example", #Displays on top of window
:pos => [150, 25], #or Wx::DEFAULT_POSITION
:size => [300, 200] #or Wx::DEFAULT_SIZE
#For the position and size arguments, you don't need to specify
Point and Size
#objects anymore. See: wxRuby Overview on the doc page
wxruby_intro.html
)
panel = Wx::Panel.new(self) #Parent = self = this Frame
drink_choices = ["coffee", "tea", "juice", "milk"] #labels for radio
buttons
radios = Wx::RadioBox.new(
panel, #Parent
:label => "Drinks", #Label for box surrounding radio
buttons
:pos => [20, 5],
:size => Wx::DEFAULT_SIZE,
:choices => drink_choices, #The labels for the radio buttons
:major_dimension => 1, #Max number of columns(see next
line)--try changing it to 2
:style => Wx::RA_SPECIFY_COLS #:major_dimension value applies to
columns
#The :major_dimension and :style in combination determine the
layout of the
#RadioBox. In this case, the maximum number of columns is 1,
which means
#there can only be one radio button per line. Because there are 4
radio buttons,
#that means there will be 4 lines, with one radio button per line.
)
evt_radiobox(radios.get_id()) {|cmd_event| on_change_radio(cmd_event)}
#When there is an event of type evt_radiobox on the widget with the id
radios.get_id(),
#the block is called and an "event object" is passed to the block. The
block calls
#the method on_change_radio(), defined below, relaying the event
object to the
#method. The event object contains useful information about the radio
button
#that was selected.
@text_widget = Wx::StaticText.new(
panel, #Parent
:label => "coffee",
:pos => [150, 25],
:size => Wx::DEFAULT_SIZE
#Store a widget in an instance variable when other
#methods, like the one below, need access to it.
)
show #equivalent to self.show, makes the frame visible
end
def on_change_radio(cmd_event)
selected_drink = cmd_event.string #Selected radio's label
#Instead of calling cmd_event.get_string() or cmd_event.set_string(),
you can
#now call an accessor method with the same name as the property you
are trying
#to get or set. See: wxRuby Overview on the doc page wxruby_intro.html
@text_widget.label = selected_drink
end
end
class MinimalApp < Wx::App
def on_init
MyFrame.new
end
end
MinimalApp.new.main_loop #main_loop() tells wxruby to start reacting
#to radio button selections, button clicks,
etc.
#on your App.
