Hello,

recently I tried porting an application to GTK3  
([Homepage of Dr. Stefan Salewski](http://www.ssalewski.de/PetEd.html.en))

using Ruby 2.0 and ruby-gnome2-2.1.0 shipped with Gentoo-Linux (AMD64)  
in default configuration.

Basically it works fine, I got some warnings about deprecated stuff  
which I fixed.

Unfortunately use of deprecated Gtk::Widget#pointer raised an exception.

/usr/lib64/ruby/site\_ruby/2.0.0/glib2/deprecatable.rb:136:in `block in __define_deprecated_method__': pet/peted.rb:588:in `distribute\_events’:  
‘Gtk::Widget#pointer’ has been deprecated. Use  
‘Gdk::Window#get\_device\_position’.

Following a recent discussion on GTK mailing list

it is difficult to avoid window.get\_pointer() when keyboard input for  
CAD applications require mouse coordinates. GTK-Developers consider  
continuing using window.get\_pointer(). So it would be nice if  
Ruby-Gnome2 would not raise an exception and abort the program in  
default setup.

Best regards,
