[Kde-bindings] problem with calling signals in block associated with Class.new and rspec

[Stefano Crocco]

I wanted to write a method which generates a Qt::Object-derived class which 
defines signals determined at runtime. The definition of the method is the 
following:

def MyModule.create *sigs
  Class.new(Qt::Object) do
    signals( *sigs)
  end
end

This is called this way:

MyModule.create 's1(QString)', 's2(QObject*, QPoint)'

and returns a new class, derived from Qt::Object, which has the two signals 
passed as argument.

When used by itself, this method works correctly, and returns a class which, 
has a 's1' and a 's2' method among its instance methods. The problem is that I 
want to test this code using RSpec. I do something like this:

describe 'MyModule.create' do
  it 'should work' do
    cls = MyModule::Signaler.create 's1()', 's2(QString)', 's3(QObject*)'
    cls.instance_methods.should include('s1')
    cls.instance_methods.should include('s2')
    cls.instance_methods.should include('s3')
  end
end

but it doesn't work. Indeed, looking at the contents of cls.instance_methods, 
one can see that 's1', 's2' and 's3' aren't there. Now, I know it's very 
likely you won't know RSpec and its internals, but I was wandering if you know 
of some edge cases which can lead to the above behaviour. I tried to look at 
the source for the signals method in the qtruby4.rb file, but I couldn't find 
any hint on what may be failing.

Thanks in advance
