Here is some code to demonstrate that
"==" doesn''t seem to work completely for colour.
The only problem I''ve noticed is when testing
against nil.
#---------------------------------------------------
require ''wx''
include Wx
class Demo
def try(arg)
if (arg == nil)
result = "Nil"
elsif (arg.is_a?(Array))
result = "Array"
elsif (arg.is_a?(Colour))
result = "Colour"
elsif (arg.is_a?(String))
result = "String"
else
result = "Unclassified"
end
puts result
end
end
bd = Demo.new
n = nil
bd.try(n)
array = %w(one two)
bd.try(array)
string = "abc"
bd.try(string)
colour = Colour.new(0, 0, 0, 255)
bd.try(colour)
An interesting work-around is to put the
Colour test *first*. However, it sure
would be nice if Colour worked like the
other objects.

It''s fixed by SVN:1990 http://rubyforge.org/pipermail/wxruby-svn-commit/2009-January/000846.html a
