2.19.6 (unstable): Gtk: * Action: Do not deprecate connect_proxy(), disconnect_proxy(), block_activate_from() and unblock_activate_from(), because we cannot yet derive existing classes from Activatable until we can break ABI. Bug #608109 (David Trowbridge) * EntryBuffer: Actually use GtkEntryBuffer. * Paned: Added get_handle_window(). * ToolTip: Added set_icon(Gio::Icon). * Widget: - Added set/get_realized(), set/get_mapped() and style_attach(). - get_requisition(): Reimplemented with the new gtk_widget_get_requisition() function. - Un-deprecate get_action() because we cannot yet derive existing classes from Activatable until we can break ABI. * Use Glib::wrap() instead of ->gobj() in some places, so we are generally more forgiving of null RefPtrs<>.
