GtkAda Tree_View properties

["Dr. Adrian Wrigley" <amtw@linuxchip.demon.co.uk.uk.uk>]

Hi guys!

Sorry this is not strictly a language question, but I figure people
here will know the answer.

Using GtkAda, I was to set properties for a Gtk_Tree_View.

The lines in the widget have rather excessive vertical spacing.
I think if I set "ypad" and/or "vertical-separator" properties,
I could reduce the spacing. (this seems to be a perennial problem
with gtk programs now. I though I had solved it, but it became unsolved)

Can't I set the properties in a gtkrc file? (this had no effect)

Thanks for any input!

                       Model   : out Gtk_Tree_Store) is

      Tree          : Gtk_Tree_View;
 
   begin

      Gtk_New (Model,
               (Age_Column        => GType_String,
 -- stuff deleted
                Strike_Column     => GType_Boolean,
                Editable_Column   => GType_Boolean,
                Active_Column     => GType_Boolean,
                Foreground_Column => GType_String));

      Gtk_New (Tree, Model);

--  What goes here?
      Set_Property (Tree, "ypad", 0); -- This does not compile
