listbox: add support for :first-child, :last-child and others

Desktop / GNOME / GTK - Christian Hergert [hergert.me] - 29 May 2015 22:03 UTC

This applies the proper CSS child ordering semantics using GtkCssNode to GtkListBox. You can now use :first-child, :last-child, :nth-child(), and :last-nth-child() selectors.

For example, this allows styling row separators using CSS while ignoring the separator on the last row.

GtkListBoxRow { border-bottom: 1px solid @borders; } GtkListBoxRow:last-child { border-bottom: none; }

When the sort ordering of the listbox changes, we also update the CSS node ordering.
