Gtk::Entry, how to get the cursor coordinates

[Angelo <angelo70 gmail com>]

I need a widget-relative x and y coords of the cursor, or even screen 
absolute coordinate of it
I've try trough the associated Pango::Layout, using get_cursor_pos, 
get_cursor_weak_pos. get_cursor_strong_pos.
As documentation say, i've convereted the Entry index in Pango index 
(tha value remain the same).

But i only get "Rectangles" structs with all zero values.


Every help is appreciated.
