Menu.append\_check\_item(), like Menu.append(), is supposed to return a  
reference to the created menu item. Here is a test code which seems to  
show  
that this behavior works for append(), but fails for  
append\_check\_item().  
This is the output I get:

% ruby test-menu.rb  
#Wx::MenuItem:0xb74c036c  
nil

Am I missing something or is this a bug? Both menu items are created  
and  
work as expected. I am running the 1.9.2 tarball.

#!/usr/bin/env ruby

begin  
require ‘wx’  
rescue LoadError =\> no\_wx\_err  
begin  
require ‘rubygems’  
load ‘wx’  
rescue  
raise no\_wx\_err  
end  
end  
include Wx

class MinimalFrame \< Wx::Frame  
def initialize(title)  
# The main application frame has no parent (nil)  
super(nil, :title =\> title, :size =\> [700, 400])

```
menu_bar = Wx::MenuBar.new

menu_file = Wx::Menu.new
item1 = menu_file.append(1000, "Test Item 1")
item2 = menu_file.append_check_item(1001, "Test Checked Item")

puts item1
puts item2

menu_bar.append(menu_file, "Test1")
self.menu_bar = menu_bar

```

end  
end

Wx::App.run do  
self.app\_name = ‘Minimal’  
frame = MinimalFrame.new(“Minimal wxRuby App”)  
frame.show  
end

Thanks,  
Bob

It’s now fixed by SVN:1486 for the next release. If you need to work  
around n the interim, you should can use the long form of append\_item  
and give Wx::ITEM\_CHECK as the fourth parameter.

Beautiful. Thanks for the confirmation, fix, and work-around.
