2005-05-18 Anders Carlsson <andersca@imendio.com> * gtk/gtktextview.c: (gtk_text_view_flush_scroll), (gtk_text_view_update_adjustments), (gtk_text_view_value_changed): * gtk/gtktextview.h: If the horizontal adjustment changes because of a change in the layout width, then do a complete redraw. This is because there might be right-aligned or centered text that needs to be redrawn.
