Error: ...uninitialized constant Wxruby2

I have already installed the wx package with ruby gem:

gem install wxruby and now I am trying to run a gui sample program. As
follow:

require ‘wx’
include Wx
class MyFrame < Frame
def initialize()
super(nil, -1, ‘My Frame Title’)
@my_panel = Panel.new(self)
@my_label = StaticText.new(@my_panel, -1, ‘My Label Text’,
DEFAULT_POSITION, DEFAULT_SIZE, ALIGN_CENTER)
@my_textbox = TextCtrl.new(@my_panel, -1, ‘Default Textbox Value’)
@my_combo = ComboBox.new(@my_panel, -1, ‘Default Combo Text’,
DEFAULT_POSITION, DEFAULT_SIZE, [‘Item 1’, ‘Item 2’, ‘Item 3’])
@my_button = Button.new(@my_panel, -1, ‘My Button Text’)
end
end

But anytime i try to run the code, I get following error message:

/ruby/lib/ruby/gems/1.8/gems/wxruby-1.9.8-x86-mingw32/lib/wx.rb:50:
uninitialized constant Wxruby2::THE_APP (NameError)

Does anybody knows how to solve this problem?

Thanks. Bou

You need to add some code at the end of your sample to actually show one
of these frames. Something like

App.run do
frame = MyFrame.new
frame.show
end

That should do the trick. You can get more help on the wxruby-users
mailing list: http://wxruby.rubyforge.org/wiki/wiki.pl?MailingLists

The error message you’re getting at the moment is a minor bug in 1.9.8,
it’s already fixed in Subversion for the upcoming 2.0 release.
