Re: [ruby-gnome2-devel-en] Gtk::TreeViewColumn initialization with area not possible

[cedlemo <ce...@gm...>]

We could use this trick

irb(main):001:0> def myfn(*args)
irb(main):002:1> puts args.size
irb(main):003:1> end
=> :myfn
irb(main):004:0> myfn("arg1","arg2","arg3")
3
=> nil
irb(main):005:0> myfn(:arg1 => "arg1", :arg2 => "arg3")
1
=> nil

If args size is equal to one then you use your code else you use the 
previous code. This way allows us to implement the has form while
we keep the compatibility with the previous code. We have done done this 
already in some of the ruby-gnome class but Kou would offer you
a better answer than me.
