Description of problem:

Exploring the migration of an application from perl-Gtk2 to perl-Gtk3, I have a problem to access a Gdk::Rectangle obtained as return value from a call of the 
"get_iter_location method of Gtk3::Textview.

Although the return value looks like a valid hash with the expected keys (x, y, width, height), an access to the hash elements (for example the "x" key) fails with.

   Can't call method "x" on unblessed reference at ./win.pl line 23.

My impression is that the method is missing because there is no Gtk3::Gdk module (I had a similar problem with Pango::TabArray, but simply using Gtk2::Pango appears a valid workaround). In this case, I have not found a workaround.

Version-Release number of selected component (if applicable):
perl-Gtk3-0.8.0-1.mga3
