Re: Tooltips for Gtk::TreeView rows

[Simon Fuhrmann <NightSlayer gmx de>]

Hello!

I changed the function from

  Gtk::TreeView::get_path_at_pos()

to

  Gtk::TreeView::get_dest_row_at_pos()

This function seems to work as expected and returns the right path.
Nevertheless, the behaviour of get_path_at_pos() is not intuitive and in
my opinion it's a bug. The get_dest_row_at_pos() is intended for drag
and drop, it's only a "workaround" to use it.

Regards,
Simon
