Hi all,

Finally, I changed my mind about Gtk.init.

Since next release, you don’t need to call Gtk.init by yourself.

# Of course, backward compatibility is remained.

If you need to call Gtk.init by yourself for some reason,  
require ‘gtk2/base’ instead of require ‘gtk2’.

(this is the smallest sample)

require ‘gtk2’  
Gtk::Window.new.show\_all  
Gtk.main

Hi Masao!

> 

I may miss something but is it really backward compatible then ?

My programs require ‘gtk2’ and call Gtk.init. Won’t it be a problem ?

Yes.

No. You can call Gtk.init twice or more. And first one is defined  
in gtk2.rb.

# Only first Gtk.init call is effective.
