2008-04-02 Christian Neumair <cneumair@gnome.org> * libnautilus-private/nautilus-icon-container.c (nautilus_icon_container_update_scroll_region), (lay_down_icons_horizontal), (get_max_icon_dimensions), (lay_down_icons_vertical), (nautilus_icon_container_start_renaming_selected_item), (nautilus_icon_container_is_layout_vertical): * libnautilus-private/nautilus-icon-container.h: * src/nautilus-window.c (nautilus_window_set_initial_window_geometry): Subtract 1 from icon rectangle's x2/y2 positions before setting scroll area since the entire canvas codes requests 1 px more than it needs. Wrap when the icon hits the canvas, rather than wrapping to late. Fixes most of the "text besides icons" glitches. Add container padding on the RHS for vertical layout, and consider max. emblem rectangles when deciding whether to wrap. This may wrap slightly to early in some (high zoom level) situations, but we will never get scroll glitches. svn path=/trunk/; revision=14025
